The multifunctional nanoparticles constructed from triphenylamine-poly(lactide-co-glycolide)-poly(ethyleneglycol)-poly(lactide-co-glycolide) (TPA-PEP) and folate-poly(2-ethyl-2oxazoline)-poly(D,L-lactide) (folate-PEOz-PLA) were developed in this study. Iron oxide nanoparticles (IOP) and paclitaxel (PTX) were coencapsulated in the nanoparticles with diameter less than 200 nm. The drug-loaded nanoparticles emit fluorescence peak at

Polymeric micelles based on poly(L-lactide)-b-poly(2-ethyl-2-oxazoline)-b-poly(L-lactide) (PLLA-PEOz-PLLA) ABA triblock copolymers were designed as intracellular drug carriers. The PLLA-PEOz-PLLA micelles adopt a "flower-like" arrangement with A-blocks at the core and a B-block on the shell under neutral condition. The deformation of the

A new series of cationic, thermo-sensitive, and biodegradable poly(L-lactide)-poly(2-ethyl-2-oxazoline)-poly(L-lactide) (PLLA-PEOz-PLLA) triblock copolymers were synthesized by ring-opening polymerization. With increasing molecular weight and crystallinity of hydrophobic PLLA blocks, the critical micellization concentrations (CMC) occurred at lower concentration. The PLLA-PEOz-PLLA aqueous solution

Poly(2-Oxazoline)S: The Versatile Polymer Platform for Biomedicine

The introduction of polymers into the biomedical field has opened new avenues in tissue engineering, implant design, biosensing, and drug delivery.

Polyelectrolyte Multilayer Films and Membrane Functionalization

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
