Low molecular weight chitosan-coated polymeric nanoparticles for sustained and pH-sensitive delivery of paclitaxel.
Low molecular weight chitosan (LMWC) is a promising polymer for surface modification of nanoparticles (NPs), which can impart both stealth effect and electrostatic interaction with cells at mildly acidic pH of tumors. We previously produced LMWC-coated NPs via covalent conjugation to poly(lactic-co-glycolic) acid (PLGA-LMWC NPs). However, this method had several weaknesses including inefficienc...
متن کاملDevelopment of pH Sensitive Nanoparticles for Intestinal Drug Delivery Using Chemically Modified Guar Gum Co-Polymer
The aim of the research work was to chemically modify guar gum(GG) as a pH sensitive co-polymer and formulating intestinal targeting ESO nanoparticles (NPs) using the synthesized co-polymer. Poly acrylamide-grafted-guar gum (PAAm-g-GG) co-polymer was synthesized by free radical polymerization. Chemical modification of PAAm-g-GG by alkaline hydrolysis results in formation of a pH-sensitive co-po...

متن کاملpH-Sensitive Core-Shell Nanoparticles for Intracellular Drug Delivery
Therapeutics such as proteins, DNA, or siRNA, can only exert their function in the cell cytosol or nucleus. However, most of them are cell membrane impermeable molecules that can only be taken up by cells via endocytosis or phagocytosis. Such drug molecules are thus confined in endolysosomes, where reduced pH and degradative enzymes may destroy them without therapeutic gain. Efficient escape of...
متن کاملInfluence of Solution Temperature and pH on Size and Morphology Improvement of Chitosan Nanoparticles as Protein Delivery Vehicles
In recent years, utilization of chitosan /tripolyphosphate nanoparticles has been considered greatly as protein delivery vehicles. Effects of a variety of factors on final characteristics of nanoparticles have been studied by many investigators. Although, the objective of this study was to achieve smaller chitosan nano carriers via changing fabrication parameters such as pH and temperature and ...
