Outline of Final Research Achievements

We successfully developped the versatile CO2/N2 responsive polymer particles as described below.
(1) CO2/N2-triggered stability-controllable gold nanoparticles (AuNPs) grafted with poly(2-(diethylamino)ethyl methacrylate) (PDEAEMA) layers (PDEAEMA-g-AuNPs) were synthesized by the surface-initiated atom transfer radical polymerization of DEAEMA with AuNPs bearing initiator groups. (2) Core-shell type moleculary imprinted polymer (MIP) particles bearing protein recognition cavities in the shell layer with switchable molecular recognition capability responding to CO2 and N2 gas. (3) Effects of comonomer and polymerization temperature on the switchable molecular recognition capability of MIP particles was investigated.
