The rate of adsorption of aqueous emulsions of DMAEMA-MMA copolymers to calcium alginate substrates was examined using ATR FT-IR spectroscopy. This work was undertaken as part of the development of a hybrid artificial pancreas. Aqueous DMAEMA-MMA copolymer emulsions containing < 25 mol% DMAEMA were slowly adsorbed to calcium alginate substrates; emulsions of 50 mol% DMAEMA-MMA copolymer were adsorbed rapidly to calcium alginate gels. The adsorption of 50 mol% DMAEMA-MMA copolymer emulsions to calcium alginate gels was attributed to electrostatic rather than simple van der Waals' attractive forces.
