Abstract

The aim of this study was to investigate the interaction of mouse embryonic cortical neurons on P(L)LA and PLGA substrates, which were partially hydrolysed using potassium hydroxide (KOH). The chemical and topographical properties of the surfaces were characterized, and it was discovered that there was a decrease in the hydrophilicity for the P(L)LA with increasing concentration of KOH. This was due to chemical modifications to the surfaces of the substrates. Alternatively for the PLGA substrate, only the 0.1 M KOH treated sample had a significantly different hydrophilicity highlighting that surface erosion resulted at higher concentrations. The morphology of the neurons grown on the two sub..
