Purdue BME Researchers Create Faster, More Precise Gelatin-Norbornene for Advanced Hydrogels and Bioprinting
Purdue Biomedical Engineering researchers have developed a rapid and highly tunable method to synthesize gelatin-norbornene (GelNB)—a widely used biomaterial for 3D cell culture and bioprinting. The new approach, reported by Jonathan Bryan and Professor Chien-Chi Lin, uses microwave-assisted aqueous synthesis to drastically shorten reaction time and improve control over a key property known as the degree of norbornene conjugation.
