Abstract
A side-by-side diffusion cell was used to study the permeability of gl ucose through a temperature- and pH-sensitive poly(N-isopropylacrylami de-co-methacrylic acid) hydrogel membrane. At fixed temperature (37 de grees C), lowering pH in one side of the cell induced hydrogel volume collapse and strongly attenuated glucose permeation across the membran e. Hysteresis was observed in the glucose permeability versus pH chara cteristic.
