|January 1, 1978
Abstract:
Oxygenator membranes, polydimethylsiloxane elastomer, exposed to flowing heparinized canine blood in a perfusion system have been studied with respect to the platelet activation and the morphology of the membranes. Utilizing Fourier transform infrared spectroscopy couple with attenuated total reflection technique (ATR) and laser Raman spectroscopy, no obvious differences in morphology and composition of the membranes have been detected while electron microscopic study shows difference in platelet aggregation.
