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
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
Tiny sensor technique reveals cellular forces involved in tissue generation
A team of researchers developed a technique that uses tiny polymer spheres to sense the forces at play as body tissue forms and grows
Tissue-engineered implants provide new hope for vocal injuries
New technology may one day help patients who suffer devastating vocal injuries from surgery on the larynx. A collaborative team consisting of biomedical engineers and clinicians has tissue-engineered component tissue replacements that support reconstruction of the larynx
