The formation of micelle-like nanosize aggregates above a critical aggregation concentration (CAC) by a water-soluble, amphiphilic, and statistical copolymer poly(SAMPS/DA) of sodium N-acrylamidomethylpropanesulfonate (SAMPS) and N-dodecylacrylamide (DA) was studied. The structural changes that result from the interactions between the polymeric

Hydrogel micropatterns of 10 approximately 200 microm in width were introduced during the polymerization of 2-acrylamido-2-methyl-propane sulfonic acid sodium salt (NaAMPS) on the surface of polyacrylamide (PAAm) gel. Behaviors of endothelial cells on the micropatterned PNaAMPS/PAAm gel surfaces were studied.

The study evaluated biological reaction of four types of novel double network gels in muscle and subcutaneous tissues, using implantation tests according to the international guideline. The implantation tests demonstrated that, although poly (2-acrylamide-2-metyl-propane sulfonic acid)/poly (N,N'-dimetyl acrylamide) (PAMPS/PDMAAm) gel

A new family of poly(NIPAAm-co-2-acrylamido-2-methyl-1-propanesulfonic acid) [P(NIPAAm-co-AMPSA)] hydrogels was synthesized by incorporating negative charged AMPSA to the backbone of the PNIPAAm-based hydrogel. The effect of polyelectrolyte (i.e., PAMPSA) on the thermosensitive property of PNIPAAm hydrogels was investigated. It was found
