Wound

Getting a bandage to stick to your skin can sometimes be difficult, particularly if that skin is wet. This isn't a problem with an experimental new wound dressing however, which uses ultrasound-induced microbubbles to better bond with the skin.

Chronic skin ulcers are notoriously slow to heal, but an otherwise-wasted material may soon help change that. Scientists at Singapore's Nanyang Technological University have developed a new regenerative wound dressing, and it's made from frog skin.

Mussels have long been known for the adhesive they produce, which allows them to cling to rocks. The protein responsible has now been utilized in a new skin grafting technique, which reportedly results in little to no scarring.

Scientists at Brown University have developed a new material that can release drugs only when pathogenic bacteria are around. When used as a bandage, the hydrogel could deliver medication on-demand when infection begins to take hold.

For some time now, it's been known that the application of electricity can help heal wounds. The experimental new ePatch bandage takes that approach, plus it boosts the healing process by killing bacteria.

For some time now, blueberries have been claimed to slow the progression of memory loss. A new study now suggests that compounds found in the berries may also help heal chronic wounds such as diabetes-related skin pressure ulcers.

While antibiotics are very effective at treating infected wounds, they should definitely be used sparingly. An experimental new bandage was designed with this fact in mind, as it only dispenses medication when it detects the heat of an infection.

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, impressing judges as clever concepts designed to solve real-world problems.

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.

When removing the dressing to check on a chronic wound, you ironically often set back the healing process. A new type of "smart bandage" was designed with this problem in mind, as it transmits wound data to an app on a clinician's mobile device.

Chronic wounds such as skin ulcers can be 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 such films.

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.
