PG - 2937-45 LID - 10.1007/s10856-010-4124-3 [doi] AB - The thermoresponsive poly(N-vinylcaprolactam) (PVCl) based cryogel network were synthesized and characterized with respect to physical and biological properties. The PVCl cryogel crosslinked with polyethylene glycol-diacrylate (PEGda) was synthesized in 1% dimethyl sulfoxide containing aqueous medium at -12 degrees C for 12-14 h. The cryogel synthesized in this manner were highly spongy in nature and can absorb water in its porous network. These polymeric cryogel networks have good physical morphology as confirmed by scanning electron microscopy. The estimated porosity of these cryogels was 90% as demonstrated by various methods based on absorption of water and cyclohexane. The median pore diameter and surface area was 30 mum and 2.0253 m(2)/g, respectively as confirmed by analysis on mercury porosimeter. These materials can interact with biological system without any cytotoxic effects. Change in temperature influenced the adsorption of fetal bovine serum (FBS) on PVCl scaffold which showed maximum protein adsorption at 37 degrees C, as compared to that at 25 degrees C. Furthermore, the fibroblast cell adhesion studies showed the potential of these PVCl based cryogels as tissue engineering scaffolds.
