Biodegradability
New hydrogels wither while stem cells flourish for tissue repair
Hydrogels, programmed to biodegrade at an optimum pace, create a fertile environment for bone stem cells to thrive and proliferate vigorously
Light activation offers non-invasive removal of medical implants
Devices incorporating a light-sensitive hydrogel break down inside the body when exposed to light from an ingestible LED capsule
Nanosize device ‘uncloaks’ cancer cells and reveals them
Scientists report they have designed and successfully tested an experimental, super small package able to deliver molecular signals that tag implanted human cancer cells in mice and make them visible for destruction by the animals’ immune systems
Researchers regrow damaged nerves with polymer and protein
Researchers have created a biodegradable nerve guide — a polymer tube — filled with growth-promoting protein that can regenerate long sections of damaged nerves, without the need for transplanting stem cells or a donor nerve
Light-activated biomimetic hydrogel for infection-beating wound dressings
The work is a good starting point for making wound dressings with “built-in infection stoppers”
Researchers use eggshell particles to grow bone tissue in the lab
Technique can be used for bone grafts and regenerating cartilage, teeth, tendons
A better way to stop bleeding
Modifying starch creates a biocompatible, biodegradable and inexpensive material that stops bleeding
Mussel glue can help heal nerves
A glue extracted from mussels and bio-active peptide molecules can help repair damaged nerves
