2021 James Dyson awardees take aim at plastics, glaucoma and stab wounds

A wearable sensor for eye pressure sensing, a plastic scanner and new treatment solution for stab wounds have triumphed as global winners of the 2021 James Dyson Award. The teams behind the inventions, which each earn US$40,000 to continue developing t… Continue reading 2021 James Dyson awardees take aim at plastics, glaucoma and stab wounds

Wound dressing releases silver nanoparticles when infections occur

Although silver is highly effective at killing bacteria, it can also be toxic to humans in large amounts. That’s where a new wound dressing is intended to come in, as it only releases its silver payload when infections are present.Continue ReadingCateg… Continue reading Wound dressing releases silver nanoparticles when infections occur

VeCare tech relays wound data while leaving the bandage in place

One of the ironies of treating chronic wounds lies in the fact that when removing the dressing to check the wound, you often set back the healing process. A new type of “smart bandage” was designed with this problem in mind, as it transmits wound data … Continue reading VeCare tech relays wound data while leaving the bandage in place

Microneedle patch penetrates biofilms to treat chronic wounds

Chronic wounds such as diabetic foot ulcers can be very difficult to treat, partially because of antibiotic-resistant “biofilms” that form over the affected tissue. A new type of microneedle patch, however, has been shown to deliver medication through … Continue reading Microneedle patch penetrates biofilms to treat chronic wounds

Hydrogel produces oxygen to help heal chronic wounds

Diabetic skin ulcers often take a long time to heal, sometimes even leading to complications that result in amputation. A new hydrogel is designed to help keep that from happening, by delivering oxygen directly to such wounds.Continue ReadingCategory: … Continue reading Hydrogel produces oxygen to help heal chronic wounds

Glowing antibacterial bandage sheds light on infected wounds

Bandaged wounds need to be checked for infection, yet removing the bandage to check the wound can delay its healing. Australian scientists may have a fix for this paradox, in the form of a dressing that glows if the wound is infected.Continue ReadingCa… Continue reading Glowing antibacterial bandage sheds light on infected wounds

Experimental chronic wound dressing made from human protein

If you’re trying to make a wound dressing that will be well-tolerated by the human body, you may be best off using human-derived materials. That’s the approach that German researchers have taken, creating a tropoelastin-based bandage.Continue ReadingCa… Continue reading Experimental chronic wound dressing made from human protein

“Intestinal bandage” designed to better heal digestive tract wounds

When it comes to closing incisions or other wounds in the digestive tract, sutures alone aren’t enough to keep digestive fluids or food waste from leaking out into the abdomen. A new hydrogel patch is designed to help, by thoroughly sealing such injuri… Continue reading “Intestinal bandage” designed to better heal digestive tract wounds

Internal-wound-healing wafer is powered by patients’ muscles

Although we’ve already heard how electrical stimulation can help speed the healing of wounds, electrical devices themselves often can’t be implanted in soft tissue. That could soon change, though, thanks to the development of a new “piezoelectric wafer… Continue reading Internal-wound-healing wafer is powered by patients’ muscles

New insight into how light therapy can speed up burn wound healing

A compelling new study is offering an insight into the mechanism by which a novel form of light therapy can speed the healing of burn injuries. The research indicates the experimental therapy can activate a key protein that stimulates cell growth.Conti… Continue reading New insight into how light therapy can speed up burn wound healing
