Artificial membranes with selective nanochannels for protein transport

Abstract

Membranes based on poly(styrene-<italic>b</italic>-4-hydroxystyrene-<italic>b</italic>-styrene) were prepared with nanochannels for preferential transport of proteins with molecular weight 14.3 kg mol⁻¹and rejection of neutral polyethylene glycol molecules with molecular size of 10 kg mol⁻¹.
