Abstract:

Penetration and reaction of tanning agents in leather greatly influence tanning performance and leather quality. Aldehyde tanning agents are widely used in leather manufacture, but their penetration and reaction in leather cannot be detected easily. Considering the fact that aldehyde can form a fluorescent Schiff base with amino groups of collagen, we visualized the distribution and reactivity of typical aldehyde tanning agents in leather during tanning process using a fluorescence microscope. The results showed that glutaraldehyde in leather was easily observed under the fluorescein isothiocy

Abstract:

A facile green method to synthesize fluorescent Ag nanoclusters (NCs) has been developed by employing glutathione (GSH) as capping agent as well as reducing agent. The fluorescent nanocomposites powder possesses strong emission and excellent stability. By changing the mole ratios of glutathione to silver precursor, nanoclusters with different emissions are obtained. The as-synthesized GSH-Ag nanocomposite is well characterized by fluorescence spectroscopy, HRTEM, XPS, and IR spectroscopy. The green synthesis procedure has also been used to synthesize fluorescent GSH-Au nanoclusters with good s

Abstract:

Comprehensive method for determining the fluorescent agents was studied through studying the fluorescence spectra of different concentration of VBL. The emission and excitation wavelength in the measurement was 275nm, and 434nm, respectively. When the concentrations of VBL are changing from 0 to 1.0 μg/mL, they have a linear relationship with the emitted fluorescence intensity. In this interval, the calibration curve is y= 1 6.713x+0.7879, showing strong correlation (correlation coefficient R2 is 0.9979). The average percentage of recovery is 89.9%, which meets the measuring requirements. The

Background and Aims: Accurate endoscopic detection of premalignant lesions and early cancers in the colon is essential for cure, since prognosis is closely related to lesion size and stage. Although it has great clinical potential, autofluorescence endoscopy has limited tumor-to-normal tissue image contrast for detecting small preneoplastic lesions. We have developed a molecularly specific, near-infrared fluorescent monoclonal antibody (CC49) bioconjugate which targets tumor-associated glycoprotein 72 (TAG72), as a contrast agent to improve fluorescence-based endoscopy of colon cancer.

Abstract:

A fluorescent agent was used instead of slurry to visualize the flow of slurry, the polishing liquid solution supplied in Chemical Mechanical Polishing (CMP). Under ultraviolet irradiation, the fluorescent agent emits light, which performs the flow of the slurry under the quartz glass, which is applied as a photomask substrate in Flat-Panel Display (FPD) manufacturing. The emitted light was observed with a digital camera. Compared to a round shape of quartz glass substrate, a large amount of fluorescent agent supplied was taken away by the straight edges of the quadrilateral geometry of the su

Abstract:

In this paper, the influence of the fluorescent bleaching agent, UVITEX BHT optical bleach, on the degree of whiteness of cotton fabric was examined. In the first phase of the test, the bleaching of cotton with hydrogen peroxide, as the bleaching agent, was done. In the second phase, the effect of fluorescent bleaching agent on the whiteness of cotton wool bleached in the first phase was tested. Moreover, the color strength (K/S) and CIE L*a*b* were determined using Coloreye - 3000 spectrophotometer. The whiteness degree achieved with bleaching agent UVITEX BHT was almost twice larger than the

Abstract:

In vivo optical imaging methods have become a cornerstone of pre-clinical cancer research. Genetically modified cells with fluorescent or bioluminescent reporters allow researchers to non-invasively study tumour proliferation and biochemistry over time. Target-specific fluorescent probes may be used to reveal specific tumour properties such as growth patterns, neovasculature formation, and compartmental probe absorbance. Herein, we demonstrate the simultaneous optical imaging of these tumour properties in a human neuroblastoma model. We used luciferase-positive cancer cells, a neovasculature s

Abstract:

The major challenge in the fabrication of fluorescent silica nanoparticles (FSNs) based on dye-doped silica nanoparticles (DDSNs) is aggregation-caused fluorescence quenching. Here, we constructed an FSN based on a double emission enhancement (DEE) platform. A thio-reactive fluorescence turn-on molecule, N-butyl-4-(4-maleimidostyryl)-1,8-naphthalimide (CS), was bound to a silane coupling agent, (3-mercaptopropyl)-trimethoxysilane (MPTMS), and the product N-butyl-4-(3-(trimethoxysilyl-propylthio)styryl)-1,8-naphthalimide (CSP) was further used to fabricate a core–shell nanoparticle through the

Abstract:

A novel fluorescent reagent for determination of ammonium, 4-methoxyphthalaldehyde (MOPA), was successfully synthesized in this study. Under alkaline conditions, MOPA could reacted with ammonium rapidly at room temperature, producing fluorescent substance which had maximum excitation at 370 nm and emission wavelength at 454 nm. Based on this, a novel fluorescence analysis method was established for the determination of trace ammonium in natural water. Experimental parameters including reagent concentration, pH, reaction equilibrium time, and metal ions masking agent were optimized. The results

Abstract:

The purpose of the study was to obtain luminescent serum based on highly purified anthracoid globulins to diagnose anthrax agents in animals. To date, there are plenty diagnostic agents that allow rapid and accurate diagnostics of infectious diseases of animals. One of them is the luminescent microscopy of the fluorescent antibody method, which is used as an express method and provides for diagnostics within 3-5 hours. Hyperimmune serum globulins prepared on two types of antigens – protective from strain 55 (VNIIVViM) and capsular from Lange-2 strain at five-fold scheme of introduction of thes
