Microfluidics has emerged as a valuable tool for the high-resolution patterning of biological probes on solid supports. Yet, its widespread adoption as a universal biological immobilization tool is still limited by several technical challenges, particularly for the patterning of isolated

A Candida antarctica lipase B (CALB)-displaying yeast whole-cell biocatalyst was constructed with the integration of the CALB cell-surface display expression cassette in the yeast genome and cell fusion by mating. Lipase hydrolytic activity of the yeast whole-cell biocatalyst subsequently increased

The pre-polymer poly(but-2-ene-1,4-diyl malonate) (PBM) and a series of PBM-based materials are shown to be degradable under physiological conditions in vitro and they are therefore presented as potential materials for biomedical applications. Four different PBM-based materials are synthesized: a PBM
