Outline of Research at the Start

A poly(ethylene glycol) (PEG) gel-based molecularly imprinted polymer (MIP) is studied aiming at enhanced separation performance for proteins. The gel-based MIP is promising in separation science but suffers from low reproducibility. For solving this issue, a novel PEG gel with enhanced mechanical property will be investigated.

Outline of Annual Research Achievements

The poly(ethylene glycol) (PEG) based molecularly imprinted hydrogel (MIH) was fabricated for the molecular recognition of the target protein. Copoly(PEG acrylate/PEG diacrylate) (copoly(PEGA/PEGDA)) hydrogel was employed in the preparation of MIH for cytochrome c recognition. A highly specific molecular recognition was realized when using the MIH as a sorbent, evidenced by (1) the MIH showed adsorption to the cytochrome c target while the non-imprinted hydrogel showed no adsorption to the target, and (2) the MIH hydrogel showed higher adsorption to the cytochrome c target than to the other unspecific proteins. When tested as the affinity substance in electrophoresis, the MIH retarded the migration of cytochrome c to a higher extent compared with the other unspecific proteins.
