Noncytotoxic polycaprolactone-polyethyleneglycol-ε-poly(l-lysine) triblock copolymer synthesized and self-assembled as an antibacterial drug carrier

Efficacy of ε-Poly-L-lysine as an Antibacterial Additive for Platelets Stored at Room Temperature

Multiple self-assembled nanostructures from an oligo(p-phenyleneethynylene) containing rod-coil-rod triblock copolymer.

Induced by systematic variation of the initial polymer concentration in toluene, various morphologies of aggregates including vesicles, spheres, onion-like structures, and worm-like fibers from a rod-coil-rod triblock copolymer, oligo(p-phenyleneethynylene)-polystyrene-oligo(p-phenyleneethynylene), were observed by transmission electron microscopy.

Preparation of self-assembled nanoparticles of chitosan oligosaccharide-graft-polycaprolactone as a carrier of bovine serum albumin drug.

Chitosan oligosaccharides graft polycaprolactone copolymer (PHCSO-g-PCL) has been synthesized via initiating the polymerization of e-caprolactone (CL) monomer through an amino group protection route using phthaloyl chitosan oligosaccharide (PHCSO) as intermediate. The grafting reaction was carried out in Pyridine at 120 °C with the hydroxyl group of the chitosan oligosaccharide (CSO) as initiat...

Giant tubular and toroidal vesicles from self-assembled triblock copolymer-polyaniline complexes in water.

An ABA type amphiphilic triblock copolymer was synthesized via ATRP and sulfonation. New self-assembled morphologies such as toroidal vesicles, giant tubular vesicles, and perforated spherical vesicles were observed from triblock copolymer-polyaniline complexes in water. The mechanism of morphology transformation at different compositions was discussed.

Hydrogen peroxide-responsive micelles self-assembled from a peroxalate ester-containing triblock copolymer.

A novel ABA triblock copolymer by using peroxalate esters as linkages was synthesized. In water, this amphiphilic copolymer self-assembled into micelles which were used as drug delivery carriers. When stimulated with hydrogen peroxide, the micelles disassembled to release drugs since the responsive peroxalate ester linkages would be cleaved after the reaction with hydrogen peroxide.
