Abstract:
In this study, a new and rapid spectrofluorometry and high performance liquid chromatography (HPLC) methods were developed for determination of metoprolol in pure and pharmaceutical dosage forms. The solvent system, wavelength of detection and chromatographic conditions were optimized in order to maximize the sensitivity of both the proposed methods. The linearity was established over the concentration range of 50-4000 ng ml-1 for spectrofluorometry and 5.0-300 ng ml-1 for HPLC methods. The intra- and inter-day relative standard deviation (RSD) was less than 4.14 and 3.86% for spectrofluorometry and HPLC, respectively. Limit of quantitation was determined as 30 and 5.0 ng ml-1 for spectrofluorometry and HPLC, respectively. No interference was found from tablet excipients at the selected assay conditions. The methods were applied for the quality control of commercial metoprolol dosage forms to quantify the drug and to check the formulation content uniformity.

Abstract:
ABSTRACT Two differentially labeled bacterial strains were monitored in near-real time during two field-scale bacterial transport experiments in a shallow aquifer in July 2000 and July 2001. Comamonas sp. strain DA001 and Acidovorax sp. strain OY-107 were grown and labeled with the vital fluorescent stain TAMRA/SE (5 [and -6]-carboxytetramethylrhodamine, succinimidyl ester) or CFDA/SE (5 [and -6]-carboxyfluorescein diacetate, succinimidyl ester). Fluorescently labeled cells and a conservative bromide tracer were introduced into a suboxic superficial aquifer, followed by groundwater collection from down-gradient multilevel samplers. Cells were enumerated in the field by microplate spectrofluorometry, with confirmatory analyses for selected samples done in the laboratory by epifluorescence microscopy, flow cytometry, and ferrographic capture. There was general agreement in the results from all of the vital-stain-based enumeration methods, with differences ranging from <10% up to 40% for the analysis of identical samples between different tracking methods. Field analysis by microplate spectrofluorometry was robust and efficient, allowing thousands of samples to be analyzed in quadruplicate for both of the injected strains. The near-real-time data acquisition allowed adjustments to the predetermined sampling schedule to be made. The microplate spectrofluorometry data sets for the July 2000 and July 2001 experiments allowed the transport of the injected cells to be related to the site hydrogeology and injection conditions and enabled the assessment of differences in the transport of the two strains. This near-real-time method should prove effective for a number of microbial ecology applications.

Abstract:
<p> The use of spectrofluorometers to examine nanomaterials is quite popular using either fluorescence or synchronous measurements. However, understanding how a material&rsquo;s optical properties can influence spectral acquisition are of great importance to accurately characterize nanomaterials. This dissertation presents a series of computational and experimental studies aimed at enhancing the quantitative understanding of nanoparticle interactions with matter and photons. This allows for more reliable spectrofluorometer based acquisition of nanoparticle containing solutions. </p><p> Chapter I presents a background overview of the works described in this dissertation. Correction of the gold nanoparticle (AuNP) inner filter effect (IFE) on fluorophore fluorescence using PEGylated AuNPs as an external reference method is demonstrated in Chapter II. The AuNP IFE is corrected to quantify tryptophan fluorescence for surface adsorbed proteins. We demonstrate that protein adsorption onto AuNPs will only induce ~ 20% tryptophan fluorescence reduction instead of the commonly assumed 100% reduction. </p><p> Using water Raman intensities to determine the effective path lengths of a spectrofluorometer for correction of fluorophore fluorescence is discussed in Chapter III. Using Ni(NO3)2 and K2Cr2O7 as Raman IFE references, the excitation and emission path lengths are found to exhibit chromophore and fluorophore independence, however path lengths are spectrofluorometer dependent. </p><p> Finally, ratiometric resonance synchronous spectroscopy (R2S2) is discussed in Chapter IV. Using a combination of UV-vis and R2S2 spectroscopy, the optical cross sections of a wide range of nanomaterials were determined. Also on-resonance fluorescence in solution is demonstrated for the first time. The nanoparticles discussed range from photon absorbers, scatterers, simultaneous photon absorbers and scatterers, all the way to simultaneous photon absorbers, scatterers, and emitters.</p>

Full text
Abstract:
Spectrofluorometric probe methods are developed and examined regarding their ability to model preferential solvation around probe molecules in binary solvents. The first method assumes that each fluorophore is solvated by only one type of solvent molecule and that each fluorophore contributes to the emission intensity. Expressions for this model are illustrated using fluorescence behavior of pyrene, benzo[e]pyrene, benzo[ghi]perylene, and coronene dissolved in binary n-heptane + 1,4-dioxane and n-heptane + tetrahydrofuran mixtures. The second method treats the solvational sphere as a binary solvent microsphere, with the fluorophore's energy in both the ground and the excited states mathematically expressed using the "nearly ideal binary solvent" (NIBS) model. Expressions derived from this model are illustrated using fluorescence behavior of 9,9'-bianthracene and 9,9*-bianthracene-10-carboxaldehyde in binary toluene + acetonitrile and dibutyl ether + acetonitrile.

Combustíveis adulterados resultam em aquecimento e aceleração do motor, além de aumentarem o consumo de combustível, a emissão de material particulado e de gases de exaustão. No Brasil, na década de 90 houve várias experiências de produção e uso de biodiesel a partir de diversas matérias-primas de origem vegetal ou animal, assim como de óleo residual. No entanto, apenas com a Portaria Nº 310 de 27/12/2001, a ANP estabeleceu as especificações para comercialização de óleo diesel e sua mistura com 2% de biodiesel e definiu obrigações dos agentes econômicos sobre o controle de qualidade do biocombustível. O trabalho visa simplificar os testes utilizados para caracterizar as misturas de biodiesel e diesel, de B00 (0%v/v de biodiesel no diesel) até B100 (100%v/v de biodiesel puro). Foi utilizada a técnica de espectrofluorimetria total 3D em combinação com Análise do Componente Principal (PCA) para identificar adulteração de bicombustível, pela mudança dos valores de concentrações de biodiesel em diesel. Os espectros de emissão fluorescente das amostras foram realizadas em um espectrofluorímetro, onde a emissão foi detectada de 230 a 800 nm em intervalos de 0,5 nm enquanto as moléculas presentes na amostra sofriam excitação em comprimentos de onda fixos na faixa de 200 a 775 nm. Outros espectros de emissão fluorescente das amostras foram obtidos excitando-se as amostras com LED de 365 nm e capturando-se a emissão na faixa de 385 a 1000 nm com incremento de 1 nm. Foram preparadas 76 amostras, todas foram analisadas através da Espectroscopia de Fluorescência Total associada à PCA e foi possível identificar adulterações de diesel em decorrência do excesso de biodiesel, ultrapassando os valores permitidos por lei.<br>Monitoring of fuel quality is important, not only because of the performance of vehicles, but due to the environmental impact of emissions of pollutants. Adulterated fuels result in heating and acceleration of the motor, besides increasing the fuel consumption, emissions and particulate matter exhaust gas . In Brazil, in the 90s there were several experiences of production and use of biodiesel from various raw materials of vegetable or animal origin, as well as residual oil. However, only with Ordinance No. 310, 27/12/2001, ANP established specifications for commercialization of diesel and its mixture with 2% biodiesel and defined obligations of economic agents about the quality control of the biofuel. The work aims to simplify the tests used to characterize mixtures of biodiesel and diesel, B00 (0% v / v biodiesel in C) to B100 (100% v / v of pure biodiesel). We used the technique of spectrofluorimetry full 3D in combination with PCA to identify adulteration of biofuel, by changing the values of concentrations of biodiesel in diesel. The fluorescence emission spectra of the samples were performed in a spectrofluorometer where the emission was detected at 230-800 nm in steps of 0.5 nm while the sample suffered excitation in wavelengths fixed at 200-775 nm. Other fluorescent emission spectra of the samples were obtained by exciting the sample with LED of 365 nm and capturing the emission in the range 385 to 1000 nm with an increment of 1 nm. Have been prepared 76 samples, all were analyzed by Fluorescence Spectroscopy Total associated with PCA and were able to identify adulteration of diesel fuel due to the excess biodiesel, exceeding the values allowed by law.

Full text
Abstract:
碩士<br>國立中興大學<br>生物化學研究所<br>90<br>The aim of this study was to characterize conformational changes in the N-terminal domain of troponin I (TnI) and to relate such changes to its regulatory functions of skeletal muscle contraction. Two Cys residues (Cys-48 and Cys-64) in the N-terminal domain of chicken skeletal TnI allow to attach conformational probes to this region. By analyzing spectrum of fluorescence probes attached at these sites, conformational changes in TnI. were characterized in association with protein-protein interactions in the presence or absence of calcium binding. Compounds which contain the pyrene group, such as N-(1-pyrene)maleimide (PM), N-(1-pyrene)iodoacetamide (PIA), and 1-pyrenemethyl iodoacetamide (PMIA) were used to study proximity relations between the two SH groups. The pyrene-labeled protein displays a characteristic fluorescence spectrum: two sharp peaks in the range from 380 to 400 nm, referred to as monomer fluorescence and one broad peak in the range from 480 to 490 nm, referred to as excimer fluorescence. The excimer fluorescence arises from the tendency of two adjacent pyrene groups to form an excited state dimmer. Thus the magnitude of the excimer fluorescence indicates the ability of the two pyrene groups to approach to within about 3~5 Å of each other. Results obtained are the followings: 1.) Two Cys residues (Cys-48 and -64) are close to each other and form pyrene excimer fluorescence. 2.) Interactions of TnI with TnT or TnC cause significant changes in excimer fluorescence, suggesting protein-protein interactions would affect the proximity of the two labeled Cys of TnI. 3.) When labeled TnI forms complex with TnT, and TnC, calcium binding causes a further decrease in excimer fluorescence (~10.7 %) and a small increase in monomer fluorescence (~6.2 %). Thus, the N terminal region of TnI may participate in the calcium-regulated skeletal muscle contraction.

Abstract:
Aflatoxin is a potent biological toxin produced by fungi Aspergillus flavus and A. parasiticus. Current quantification methods for aflatoxins are mostly established on immunoaffinity columns which are both costly and labor intensive. Inspired by smectites’ high aflatoxin adsorption capacity and affinity, a novel aflatoxin quantification sensor based on smectite-polyacrylamide (PAM) nanocomposite was fabricated. First, a smectite-PAM nanocomposite film was synthesized on flat silicon substrates which assembled smectite particles from the clay suspension. A layer-by-layer assembly process was developed to achieve uniform morphology and thickness of the nanocomposite films. During the aflatoxin quantification process, positive correlations between the fluorescence intensity from the aflatoxin B1 (AFB1) adsorbed smectite-PAM nanocomposite films and the AFB1 concentration in the test solutions were obtained. The smectite-PAM nanocomposite film has shown similar AFB1 adsorption capabilities as the smectite. Second, the smectite-PAM nanocomposite film was optimized in order to achieve the aflatoxin quantification at ppb level (below 20ppb) in corn extraction solutions. The smectite was modified by Ba2+, which had demonstrated to be able to improve its aflatoxin adsorption capacity. PAM aqueous solutions with the mass concentration ranging from 0.8% to 0.001% were tested. The results showed that the nanocomposite synthesized from 0.005% concentration of PAM solution generated the best properties. After the optimization, the smectite-PAM nanocomposite films achieved the detection of aflatoxin B1, B2, G1 and G2 (AFB2, AFG1 and AFG2) in 10 ppb corn extraction solution. Aflatoxin quantifications in AFB1 and AFB2 mixture solution, AFB1 and AFB2 mixture solution and AFB1 and AFG1 mixture solution were conducted, and the recoveries of last test ranged from 90.52% to 110.11% at low aflatoxin concentration (below 20 ppb). Third, in order to shorten the quantification duration and simplify the detection process, a novel aflatoxin detection array based on smectite-PAM nanocomposite and an improved fluorometric quantification method were developed. Through a microfluidic chip, the reaction time was reduced to 10~20min. Two concentration levels (20~80ppb/5~15ppb) of aflatoxin B1 spiked corn extraction solutions were tested. In the fluorometric quantification step, a common lab-use 365 nm ultraviolet lamp replaced the spectrofluorometer which simplified and accelerated the process.

Abstract:
Abstract This paper presents the development of a prototype automated device designed to monitor sea water quality and provide early warnings of potential harmful algal bloom (HAB) outbreaks. HABs pose a significant threat to aquaculture operations and marine ecosystems due to their ability to cause mass mortalities of fish and shellfish. The device integrates a low-cost custom spectrofluorometer capable of measuring absorption and fluorescence spectra of liquid samples, and an automated plankton imager adapted from an open-source design. Key aimed sensing parameters include nutrients, chlorophyll, water temperature, and phytoplankton presence. The affordability of the device is targeted by using low-cost components and integrating the spectrofluorometer and plankton imager into a single unit driven by an embedded computer. Machine learning algorithms are employed for real-time anomaly detection from the multivariate sensor data streams to provide early alerts of potential HAB events. Initial results demonstrate the device’s ability to detect low concentrations of fluorescent dyes and phytoplankton, and the effectiveness of an adaptive anomaly detection approach on real aquarium data.

Abstract:
Mineral fertilizers lose their effectiveness. It improved by adding microbiological fertilizers. Six bacterial strains were isolated and characterized, and their agronomic potential was studied. A dense nutrient medium was optimized. Two strains were found to enter into antagonistic relationships with P. chlororaphis 449. Spectrofluorometry showed the accumulation of siderophores. Strains were determined using spectrometry and Sanger sequencing methods.

Abstract:
The effectiveness of photodynamic therapy (PDT) as an adjuvant treatment for diverse malignant tumors has been investigated in numerous studies. The therapeutic success and extent of side effects of PDT is mainly determined by the applied photosensitizer (PS) and laser energy. Adjuvant intraoperative photodynamic therapy (AIOPDT) using the PS mTHPC (meso-Tetrahydroxyphenylchlorin) causes selective tumor cell death when combined with laser irradiation of a PS specific wavelength (652 nm). Our study proved AIOPDT as an efficient modality to significantly increase postoperative recurrence-free survival after R1/R2 resection of a subcutaneously implanted soft tissue sarcoma in mice. We used mTHPC in a dose of (0,3 mg/kg BW) and a laser light energy of 5 Joule (irradiation time: 50 seconds). First results showed an increase of postoperative recurrence-free survival (Median: 103 days) in 5 animals treated with AIOPDT compared to a control group of 7 animals (Median: 20 days). The tissue specific accumulation of mTHPC was determined by point spectrofluorometry and showed a 2.28 higher PS-accumulation in the tumor center, tumor bed (1.5) and overlying skin (3.8) compared to muscle tissue (1.0) as reference parameter. Our first experimental data recommend AIOPDT to be an efficient adjuvant method to prolonge recurrence-free survival after tumor resection.
