Comicellization of a star block copolymer poly(ε-caprolactone)-block-poly(diethylamino)ethyl methacrylate (S(PCL-b-PDEAEMA)) and a linear block copolymer methoxy poly(ethylene glycol)-block-poly(ε-caprolactone) (mPEG-b-PCL) was developed to enhance the stability and lower the cytotoxicity of micelles. The two copolymers self-assembled into mixed micelles with a common PCL core surr...

关键字：silver nanoparticles; star-shaped copolymers; poly(ε-caprolactone); coordination reduction; nanoreactors; catalytic activity.
Silver nanoparticles (Ag NPs) were prepared via in-situ reduction of silver nitrate (AgNO3) using polymeric micelles as nanoreactors without any additional reductant. The micelles were constructed from the amphiphilic star-shaped copolymer composed of poly(ε-caprolactone) (PCL) segment, 2-(Dimethylamino)ethyl methacrylate (DMAEMA or DMA) units and oligo(ethylene glycol)monomethyl ether met...

Interfacial Curvature Effects in The Self-assembly and Responsiveness in Polypeptide-based Star and Triblock Copolymers
This study involves the bottom-up design and tunability of responsive, peptide-based block
opolymers. The self-assembly of amphiphilic block copolymers is dictated primarily by the alance between the hydrophobic core volume and the hydrophilic corona. In these studies,mphiphilic triblock and star copolymers containing poly(lysine) (PK) and poly(glutamic acid) (PE)were synthesized and their sol...

Nanogel Star Polymers as Interesting Soft Colloid Materials for Biomedical Applications: No Assembly Required
Polymers have numerous biomedical applications including delivery of therapeutic materials,
imaging applications, tissue regeneration, antimicrobial action and others. We have developed a
route to nanogel core star polymer amphiphiles with control over size, arm number, functionality,
end groups and molecular architecture. Variants of these materials were originally developed to
serve as sacri...
