Hydrogels composed of PVP, PEG and agar, produced by simultaneous crosslink
ing and package sterilization by ionizing radiation, are used mainly as wou
nd dressing. In this study, membranes prepared in different conditions were
tested for their properties including in vitro biocompatibility. The resul
ts showed that the mechanical properties were in an acceptable range of val
ues and that the membranes can be considered as non toxic and non hemolytic
to the cells. (C) 1999 Elsevier Science Ltd. All rights reserved.
