DOI: 10.1016/j.polymer.2018.06.037

Abstract: Abstract In this contribution, shape memory polymers (SMPs) of chemically-crosslinked zwitterionic polyurethanes (CZPUs) were fabricated by crosslinking of the N,N-bis(2-hydroxyethyl) isonicotinamide (BINA)/hexamethylene diisocyanate (HDI) polyurethanes system by using pentaerythritol (PER), followed by zwitterionization with 1,… read more here.

DOI: 10.3390/biom10050754

Abstract: Hydrogel-supported neural cell cultures are more in vivo-relevant compared to monolayers formed on glass or plastic substrates. However, there is a lack of synthetic microenvironment available for obtaining standardized and easily reproducible cultures characterized by… read more here.

DOI: 10.3390/biomedicines11030706

Abstract: Linear polyethyleneimine (L-PEI) was obtained from the acidic hydrolysis of poly(2-ethyl-2-oxazoline) and employed in the synthesis of physically crosslinked L-PEI hydrogel, PC-L-PEIH, chemically crosslinked L-PEI hydrogel, CC-L-PEIH, and cryogels, CC-L-PEIC. The preparation of L-PEI-based hydrogel… read more here.
