Researchers share their first steps towards growing fully transplantable human organs in a pig host
Growing human organs for therapeutics and transplantation
Biotechnology
Antioxidant nanoparticles promise osteoporosis treatment
Porous silica nanoparticles impregnated with nanoceria offer novel way to treat osteoporosis
Changing the silkworm’s diet to spin stronger silk
Researchers have produced cellulose nanofiber (CNF) synthesized silk naturally through a simple tweak to silkworms’ diet. Mixing CNF with commercially available food and feeding the silkworms resulted in a stronger and more tensile silk
DNA origami makes 3D superconducting nanostructures
Complex three-dimensional nanostructures could find use in quantum computing and magnetic field sensing
Additive manufacturing personalizes implants
Additive manufacturing offers the possibility of tailoring polyethylene implants to individual patients and improving tissue regrowth
Researchers use cutting edge technology to bioprint mini-kidneys
Researchers bioprinted miniature human kidneys in the lab, paving the way for new treatments for kidney failure and possibly lab-grown transplants
New shape-changing 4D materials hold promise for tissue engineering
New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a team of researchers
Hydrogel promotes wound healing better than traditional bandages, gauzes
Hydrogel dressings, which have advanced in recent years, are good at promoting wound healing and can better meet the demands of different situations. Many are antibacterial, biodegradable, responsive, and injectable and can fill irregularly shaped wounds
FRESH 3D-printing platform paves way for tissues, organs
Bioprinting approach solves the issue of gravity and distortion by printing within a yield-stress support bath that holds the bioinks in place until they are cured
