Abstract (sommario):
The chromatographic properties of various silicone stationary phases for capillary gas chromatography have been extensively studied, yet the properties of nonsilicone phases have not been so well investigated. The most popular nonsilicone phases are the high molecular weight polyethylene glycols (HMW PEG) which are commercially available in a wide range of molecular weights, crossâ linkable and uncross-linkable (Carbowax 2OM and 4OM, the Superox series, etc.). Their most outstanding features are their unique polarity and selectivity; for this reason these phases are widely used in the analys

Nanopores have been shown to be a useful analytical tool for single molecule detection. They have been used to study the composition of DNA and other molecules of interest. These pores are usually α-hemolysin which is a toxin from Staphylococcus aureus or more recently nanoscale synthetic solid state pores. Now we are beginning to look at other molecules or proteins by sending them into the nanopores and measuring a characteristic partial current blockade. In this thesis we look at polyethylene glycol (PEG) as it enters and blocks current through a single alpha hemolysin pore. We report the ef

Abstract (sommario):
The pulmonary delivery of drugs is an attractive route of administration because of the large surface area and high permeability of the airway epithelium. The large majority of inhaled drugs are used to manage asthma and Chronic Obstructive Pulmonary Disorder (COPD), such as inhaled corticosteroids and β2-adrenergic receptor agonists. Local delivery of small molecules often results in sub-optimal pharmacokinetics characterised by short absorption times (tmax) and high systemic concentrations (Cmax). Numerous drug delivery strategies have been attempted to increase lung retention time, includin

Fluorescent carbon dots (C-dots) are well known for their low cell-cytotoxicity, biocompatibility, low preparation cost, excitation dependent photoluminescence, and excellent photostability.

In this work, we report fluorescent self-passivated carbon nanodots (CNDs) synthesized from PEG by using it as a carbon source as well as a passivating agent. Importantly, the addition of graphene

However, quantification of PEGylated proteins with protein-specific sandwich enzyme-linked immunosorbent assay (ELISA) is not sensitivity due to the shielding effect of PEG that prevents the binding of protein-specific antibody. To overcome this problem, an optimized anti-PEG sandwich ELISA developed with anti-PEG antibodies (AGP4 and biotinylated 3.3) was used to measure PEGylated protein drugs as well as PEG (12kDa)–interferon α-2b (PEG-IntronR) and PEG (40kDa)–

碩士<br>國立成功大學<br>化學工程學系<br>86<br>Abstract We attempted to synthesize a series block copolymers of Polystyrene-(Polyethylene glycol) by two methods：One is iniferter system and the other is macroazoinitiator system. Block copolymers involved different PEG''s molecular weights ,600、2000、4000, in the polymer chains. The prepared polymers thus contained 34∼89 wt% of PS hard segments obtaining from elemental analysis (EA). Gel permeation chromatography (GPC) was used to determine th

Abstract (sommario):
<p>Intervertebral disc (IVD) disorders and age-related degeneration are believed to contribute to low back pain. There is significant interest in cell-based strategies for regenerating the nucleus pulposus (NP) region of the disc; however, few scaffolds have been evaluated for their ability to promote or maintain an immature NP cell phenotype. Additionally, while cell delivery to the pathological IVD has significant therapeutic potential for enhancing NP regeneration, the development of injectable biomaterials that retain delivered cells, promote cell survival, and maintain or promote an NP

Abstract (sommario):
碩士<br>國立臺北科技大學<br>有機高分子研究所<br>105<br>Sulfated monooleate polyethylene glycol polyester is an anionic surfactant, which can be produced by the reaction of monooleate polyethylene glycol (PEG300MO) with sulfamic acid. The sulfation efficiency is usually influenced by the water content of PEG300MO, as well as the mole ratio of reactants. Theoretically, the lower the water content and the higher the sulfamic acid, the better the sulfation efficiency. However, it takes a lot of energy and time to obtain low-moisture PEG300MO in an industrial scale. Using a high proportion of sulfamic acid also incr
