Rice bioengineers pioneer techniques for knee repair
...replacement transplant tissues involved the use of biodegradable implants that are seeded with donor cells and growth factors. These implants, which engineers refer to as scaffolds, foster the tissue growth process by acting as a template for new growth, but they always present a risk of toxicity due to the fact t...ICCL and CI launch global mapping project to protect sensitive marine areas

...ts and others seeking perpetual youth. Catgut, the biodegradable sutures made from cow or horse intestines and used in surgery to minimize scarring, is also a form of collagen. But for such a commonplace and useful protein, collagen has defied the efforts of biomedical researchers who have tried mightily to synth...FDA approves first medical device using Rutgers biomaterial
...dical device for hernia repair that incorporates a biodegradable technology developed at the university. This action signals a paradigm shift in the application of biomaterials from permanent prosthetic replacements toward regenerative medicine, in which materials help the body to repair itself and are then resorb...New biomimetic process used to grow artificial bone for better implants and prosthetics
...r implant materials such as tantalum, alumina, and biodegradable polymer composites. Excellent results are being achieved with a new biomimetic process that involves immersion in simulated body fluid (SBF). This leads to the spontaneous formation of a bone-like apatite layer on the alloy. However, the apatite form...Targeted drug delivery achieved with nanoparticle-aptamer bioconjugates
