Redox-Responsive Polyphosphate Nanosized Assemblies: A Smart Drug Delivery Platform for Cancer Therapy
Novel redox-responsive polyphosphate nanosized assemblies based on amphiphilic hyperbranched multiarm copolyphosphates (HPHSEP-star-PEPx) with backbone redox-responsive, good biocompatibility, and biodegradability simultaneously have been designed and prepared successfully. The hydrophobic core and hydrophilic multiarm of HPHSEP-star-PEPx are composed of hyperbranched and linear pol...

[RSC Advances] Au Nanoparticles-Loaded PDMAEMA Brushes Grafted Graphene Oxide Hybrid Systems for Thermally Smart Catalysis
A novel smart catalytic system was successfully constructed by using poly[(dimethylamino)ethyl methacrylate] (PDMAEMA) brushes grafted graphene oxide (GO) to load gold nanoparticles (Au NPs). The catalytic activity of Au NPs was finely tuned by temperature, which can control the inclusion and ‘exposure’ of Au NPs inside PDMAEMA brushes via the phase transition of grafted PDMAEMA chain triggered ...

[Chem Commun] A Smart Hybrid System of Au Nanoparticles Immobilized PDMAEMA Brushes for Thermally Adjustable Catalysis
A smart hybrid system was prepared by introducing the temperature responsive PDMAEMA brushes and Au NPs to silica NPs through self-initiated photografting and photopolymerization (SIPGP) and reduction of HAuCl4. The obtained SiO2@PDMAEMA/Au hybrid system was investigated to have a thermal adjustable catalytic activity for the reduction of 4-nitrophenol.

Biodegradable Poly(ε-caprolactone)-g-Poly(2-hydroxyethyl methacrylate) Graft Copolymer Micelles as Superior Nano-Carriers for “Smart” Doxorubicin Release
Biodegradable micelles were prepared from poly(ε-caprolactone)-g-poly(2-hydroxyethyl methacrylate) (PCL-g-PHEMA) graft copolymers and investigated for controlled release of doxorubicin (DOX). PCL-g-PHEMA copolymers were readily obtained by controlled ring-opening copolymerization of acryloyl cyclic carbonate and ε-caprolactone, Michael-type conjugate addition reaction with cysteami...

Smart Assembly Behaviors of Hydroxypropylcellulose-graft-poly(4-vinyl pyridine) Copolymers in Aqueous Solution by Thermo and pH Stimuli
Thermo- and pH-sensitive graft copolymers, hydroxypropylcellulose-graft-poly(4-vinyl pyridine) (HPC-g-P4VP), were synthesized via atom transfer radical polymerization (ATRP) and characterized. The thermo- and pH-induced micellization and stimuli-responsive properties of HPC-g-P4VP graft copolymers in aqueous solution were investigated by transmittance, 1H NMR, dynamic light scattering (DLS), and s...
