(a) Cell viability analyzed via MTS assay for NCTC L929 fibroblasts co-cultured for 24 h with the hydrogel degradation products for 10%, 10% crosslinked with GE, and 30% Cs in relation to NIPAAm. The dashed line delineates 70% viability, below which is deemed cytotoxic, as designated by the ISO 10993–5 [35]. (b) Degradation profile of Cs-g-PNIPAAm in DDW over eight weeks. (c) Release profiles of RALA/pEGFP-N1 NPs) from 5% w/v 10% Cs and 30% Cs-g-PNIPAAm hydrogels in DDW at 37 °C. Values represent mean ±SEM (n = 3).
