Biodegradable polymeric nanoparticles (NPs) have been used frequently as nanocarriers for anticancer drugs. Linoleic acid conjugated SN38 (LA-SN38)-loaded NPs (EBNPs) were developed using biodegradable poly (ethylene oxide)-poly (butylene oxide) (PEO-PBO) diblock copolymer by titration hydration method without using a toxic

An amphiphilic block copolymer poly(ethylene oxide)-b-poly(butylene oxide) (PEO-PBO) was evaluated as a carrier for therapeutic delivery of paclitaxel (PTX). PEO-PBO and PTX form nanoparticles (NPs) by self-assembly upon hydration. The size of these NPs was about 92.71nm and the zeta

Poly(ethylene oxide)-block-poly(styrene oxide) (PEO-b-PSO) and PEO-b-poly(butylene oxide) (PEO-b-PBO) of different chain lengths were synthesized and characterized for their self-assembling properties in water by dynamic/static light scattering, spectrofluorimetry, and transmission electron microscopy. The resulting polymeric micelles were evaluated for their ability
