Although bone has some capacity to regenerate, large bone defects cannot be healed without major medical procedures. Metallic implants are widely used, but their bioinertness poses a challenge. In Biointerphases, researchers showcase approaches that are alternatives to metallic implants and use natural polymer coatings to improve bone-implant integration, also known as osseointegration. Establishing a strong chemical interaction between a metal and a completely organic and natural polymer is a significant advancement in bone tissue engineering.
Researchers at the University of Delaware’s Center for Plastics Innovation (CPI) have developed a process called hydrocracking to convert single-use plastic waste into ready-to-use molecules for jet fuels, diesel and lubricants.

It’s what causes unwanted deposits of protein to form during some food production or on biomedical implants, causing them to fail. Researchers at Rensselaer Polytechnic Institute are harnessing this process, which is typically considered a persistent challenge, to develop a versatile and accessible approach for modifying solid surfaces.
