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

Liquid-metal energy harvester works underwater – and on dry land

Although there are now a number of devices that generate electricity via movement, most of them only work in dry environments. A new one, however, also functions underwater – meaning it could be used in aquatic settings, implants, or wearables that reg… Continue reading Liquid-metal energy harvester works underwater – and on dry land

Sunflower pollen may find use in a better, stronger 3D-bioprinting ink

When it comes to the 3D bioprinting of replacement body parts or other implanted items, the material that’s used needs to be strong yet flexible, and also biocompatible. According to new research, sunflower pollen may be the way to go.Continue ReadingC… Continue reading Sunflower pollen may find use in a better, stronger 3D-bioprinting ink

“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

Hydrogel for the heart may prevent a common post-surgical complication

After open-heart surgery has been performed, the scar tissue that forms on the heart will sometimes stick to the tissue surrounding it. Such complications are known as adhesions, and a new hydrogel may help keep them from occurring.Continue ReadingCate… Continue reading Hydrogel for the heart may prevent a common post-surgical complication

Gel patch may one day deliver MS drugs through the nose into the brain

Getting traditionally administered drugs into the brain can be challenging, due to the body’s protective blood-brain barrier. There may be new hope, however, in the form of a patch that gets shoved up the patient’s nose.Continue ReadingCategory: Medica… Continue reading Gel patch may one day deliver MS drugs through the nose into the brain

AquaDust gel reveals water levels of plant leaves

If you want to know how much water a plant is taking up, one of the best places to look is in its leaves. A new material known as AquaDust could help scientists more easily do so, without harming the plant.Continue ReadingCategory: ScienceTags: Cornell… Continue reading AquaDust gel reveals water levels of plant leaves

“Micro-tree” hybrid harvester purifies water and wrings it out of air

Water scarcity is one of humanity’s most pressing problems. Now engineers at Caltech have developed a new system that can tap into two different sources to produce fresh drinking water, by purifying dirty water during the day and collecting droplets fr… Continue reading “Micro-tree” hybrid harvester purifies water and wrings it out of air

Hydrogel wound dressing uses immune system proteins to kill bacteria

It’s no secret that the more we use antibiotics, the greater the chances that bacteria will develop a resistance to them. A new antibacterial wound dressing is designed to get around that problem, by using proteins instead of conventional antibiotics.C… Continue reading Hydrogel wound dressing uses immune system proteins to kill bacteria
