Assessment of biocompatibility for citric acid crosslinked starch elastomeric films in cell culture applications.

This study investigates the synthesis of potato starch elastomers reinforced with silicon dioxide (SiO) and citric acid as a crosslinking agent to enhance their mechanical and barrier properties. Surface morphology analysis using optical microscopy revealed that pure potato starch films had uneven surfaces. However, higher SiO concentrations increased roughness, while citric acid crosslinked films displayed smoother surfaces overall.
