hackingbear shares a report from CNN: A team of researchers from Zhejiang University School of Medicine in Hangzhou, China, created a gel composed of a network of proteins, inspired by the matrix composition of human connective tissues, and other molecules. The product, which requires ultraviolet light to activate, can adhere within seconds and then bond to wet biological tissue surfaces without suturing. In pigs, the bio-glue sealed a punctured carotid artery, a major blood vessel in the neck, in less than a minute and also filled holes in the cardiac wall. The Chinese researchers monitored their post-surgical pigs for a two-week recovery period and saw natural healing with no abnormalities or unusual inflammation. Around the globe, more than 234 million surgeries are performed each year, the World Health Organization estimates. Additional research confirming the safety of this product is needed before experiments can begin in humans, according to the authors of a study published Wednesday in the journal Nature Communications.
