Researchers develop smart contact lens sensor for point-of-care eye health monitoring

A research group led by Prof. DU Xuemin from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences has developed a "smart" contact lens that can show real-time changes in moisture and pressure by altering colors.

New quick and convenient microfluidic chip to assess male fertility

Current tests for male fertility include measuring the concentration and motility of spermatozoa. However, other characteristics of sperm, such as their ability to follow a chemical trail to the egg, can influence the likelihood of fertilization.

Researchers develop new way to monitor radiation doses for cancer patients

More than half of all cancer patients undergo radiation therapy and the dose is critical. Too much and the surrounding tissue gets damaged, too little and the cancer cells survive.

New 'smart' diaper can alert caregiver when it is time to change

For some infants, a wet diaper is cause for an instant, vociferous demand to be changed, while other babies may be unfazed and happy to haul around the damp cargo for lengthy periods without complaint. But if worn too long, a wet diaper can cause painful rashes, and miserable babies -- and parents.

Novel hydrogels degrade while stem cells flourish for tissue repair

Baby diapers, contact lenses and gelatin dessert. While seemingly unrelated, these items have one thing in common -- they're made of highly absorbent substances called hydrogels that have versatile applications.

3D-printed scaffolds engraved with grooves hold promise for healing injuries

Who ever said bioengineers can't get their groove on? The Rice University team led by Antonios Mikos says otherwise with its development of a groovy method to seed sophisticated, 3D-printed tissue-engineering scaffolds with living cells to help heal injuries.

Novel approach allows SL printers to fabricate finer, more complex microfluidic networks

First introduced in the 1980s, stereolithography (SL) is an additive manufacturing process that prints 3D objects by the selective curing of liquid polymer resin using an ultra-violet (UV) light source in a layer-by-layer fashion.

Team finds a way to removes GI device without using endoscopy

Researchers at Massachusetts Institute of Technology (MIT) have potentially found a way to eliminate some of the endoscopic surgeries need to remove gastrointestinal (GI) medical devices.

Research could be starting point for wound dressings with 'built-in infection stoppers'

Infections are a dreaded threat that can have fatal consequences after an operation, in the treatment of wounds, and during tissue engineering.

Artificial ionic skin could lead to future advancements in wearable technology

University of Toronto Engineering researchers have developed a super-stretchy, transparent and self-powering sensor that records the complex sensations of human skin.

New hydrogel prevents and treats infections in wounds

Researchers at Lund University in Sweden have developed a new hydrogel based on the body's natural peptide defense.

Researchers show new potential path to improve bone-repair procedures

Researchers are moving closer to a new approach for improving spinal fusion procedures and repairing broken or defective bones that avoids an over-production of bone that commonly occurs in current treatments.

Brazilian researchers create hepatic organoids by 3D bioprinting

Using human blood cells, Brazilian researchers have succeeded in obtaining hepatic organoids ("mini-livers") that perform all of the liver's typical functions, such as producing vital proteins, storing vitamins, and secreting bile, among many others.

Biocompatible hydrogels could help heal wounds, deliver drugs and treat cancer

Hydrogels for healing, synthesized from the molecules up by Rice University bioengineers, are a few steps closer to the clinic.

Researchers develop 'scar in a dish' model to closely mimic progressive organ scarring

Every organ in the body is capable, to some extent, of repairing itself after an injury. As part of this process, scar tissue forms and then recedes to make room for normal tissue when healing is complete.

Researchers develop spray gel for frostbite injuries

Mountaineers and winter sports enthusiasts know the dangers of frostbite -- the tissue damage that can occur when extremities, such as the nose, ears, fingers and toes, are exposed to very cold temperatures. However, it can be difficult to get treated quickly in remote, snowbound areas.

Novel nanopipette pH biosensor could help with cancer diagnosis and treatment

Nanopipettes with zwitterionic membranes may offer improved monitoring of changes in pH surrounding living cells, which can indicate traits of invasive cancer cells and their response to treatment, report researchers at Kanazawa University in Nature Communications.
