pH-Sensitive doxorubicin conjugated polymeric micelles entrapped with near infrared (NIR) photosensitizer BODIPY (which works as an imaging agent at the same time) were designed and synthesized by ring opening polymerization of N-carboxyanhydride with mPEG-NH2 as the initiator, following reaction with doxorubicin to form the hydrazone-bond linker for pH responsiveness. Then the NIR dye (BODIPY)...
Micellar electrokinetic chromatography (MEKC), one of the major capillary electrophoresis (CE) modes, has been interfaced to mass spectrometry (MS) to provide high sensitivity and selectivity for analysis of chiral compounds. The research in this dissertation presents the development of novel polymeric glucopyranoside based molecular micelles (MoMs) (aka. polymeric surfactants) and their applic...
With the successful development of organic/polymeric light emitting diodes, many organic and polymeric fluorophores with high quantum efficiencies and optical stability were synthesized. However, most of these materials which have excellent optical properties are insoluble in water, limiting their applications in biological fields. Herein, we used micelles formed from an amino-group-containing ...
By combining three mutually immiscible polymeric components in a mixed-arm star block terpolymer architecture, we have observed the formation of a previously unknown class of multicompartment micelles in dilute aqueous solution. Connection of water-soluble poly(ethylene oxide) and two hydrophobic but immiscible components (a polymeric hydrocarbon and a perfluorinated polyether) at a common junc...
Dramatic advances in biological research have revealed the mechanisms underlying many diseases at the molecular level. However, conventional techniques may be inadequate for direct application of this new knowledge to medical treatments. Nanobiotechnology, which integrates biology with the rapidly growing field of nanotechnology, has great potential to overcome many technical problems and lead ...
The high incidence of bacterial infection and the growing resistance of bacteria to conventional antibiotics have resulted in the strong need for the development of new generation of antibiotics. Nano-sized particles have been considered as novel antibacterial agents with high surface area and high reactivity. The overall antibacterial properties of antimicrobial nanostructures can be significa...
Celastrol has been found to be a potent anti-inflammatory and antitumor plant derivative recently. Herein we established an accurate reverse phase HPLC (RP-HPLC) determination method of celastrol, and prepared an effective nanoscale drug delivery system from the optimized formulations of celastrol-loaded carboxyl functioned poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene ...
Biodegradable polymeric micelles, self-assembled from a di-block copolymer of poly(D,L-lactic-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG), were prepared to achieve folate receptor targeted delivery of doxorubicin (DOX). In the di-block copolymer structure of PLGA-b-PEG, DOX was chemically conjugated to a terminal end of PLGA to produce DOX-PLGA-mPEG, and folate was separately conju...
