Glucose-sensitive hydrogels were prepared by the copolymerization of diethylaminoethyl methacrylate (DEAEM), poly(ethylene glycol) monomethacrylate (PEGMA) and functionalized glucose oxidase (GOD) and catalase in solution. Tetra(ethylene glycol) dimethacrylate (TEGDMA) was used as the crosslinking agent. The equilibrium and dynamic swelling properties were studied to investigate the pHsensitive...

Polymeric networks that have inherent capabilities to recognize different molecules and chemical changes in their environment are the next generation of materials that will aid in the diagnosis and treatment of diseases. We have prepared new networks based on star polymers that were designed to be responsive and recognitive. Using molecular imprinting with D-glucose and crosslinking with poly(e...

Copolymerization of racemic alpha-olefins with ethylene and propylene was carried out in the presence of enantiopure C1-symmetric ansa metallocene, {1,2-(SiMe2)2(eta5-C5H-3,5-(CHMe2)2)(eta5-C5H3)}ZrCl2 to probe the effect of the polymer chain end on enantioselection for the R- or S-alpha-olefin during the kinetic resolution by polymerization catalysis. Copolymerizations with ethylene revealed t...

Copolymerization of racemic -olefins with ethylene and propylene was carried out in the presence of enantiopure C1-symmetric ansa metallocene, {1,2-(SiMe2)2( -C5H-3,5-(CHMe2)2)( -C5H3)}ZrCl2 to probe the effect of the polymer chain end on enantioselection for the Ror S-olefin during the kinetic resolution by polymerization catalysis. Copolymerizations with ethylene revealed that the polymer cha...

Convenient methods for the rapid, parallel synthesis of diversely functionalized nanoparticles will enable discovery of novel formulations for drug delivery, biological imaging, and supported catalysis. In this report, we demonstrate parallel synthesis of brush-arm star polymer (BASP) nanoparticles by the "brush-first" method. In this method, a norbornene-terminated poly(ethylene glycol) (PEG) ...
