This wound dressing is also highly biocompatible, biodegradable, and has a porous structure that allows cells to grow into the dressing. Author's Bio: CD Bioparticles is an established drug delivery company which provides customized solutions for developing and producing new, biocompatible drug ...
Janine Benyusrefers in her books to spiders that create web silk as strong as the Kevlar used in bulletproof vests. Engineers could use such a material—if it had a long enough rate of decay—for parachute lines, suspension bridge cables, artificial ligaments for medicine, and many other purpo...
In this approach to biomaterials, regardless of material and process, one issue is clear: the current built environment requires more than solid and static materials. It requires materials that can autonomously remodel, regenerating, growing and adapting in response to their environment. That seems li...
The definition of a biomaterial is a material thatis designed with the purpose to interact with the body, i.e. it is designed to reside in a biological environment. What is the main property of a biomaterial? Thetensile strength, yield strength, elastic modulus, corrosion, creep, and hardnes...
