Microneedle Skin Patch Measures Cancer Biomarkers

Researchers at the Harvard Wyss Institute have developed a technique that lets clinicians to characterize and monitor melanoma. The system involves using a microneedle patch that can draw deep interstitial fluid into itself through a series of penetrating hyaluronic acid needles. The needles can later be dissolved to release the biomarkers into a t (Read more...)

Microneedle Patch for Antibiotic-Free Acne Treatment

Researchers at the University of Hong Kong have developed a microneedle patch for the drug-free treatment of skin infections, such as acne. Acne is often treated using antibiotics, but these have limited effectiveness over the long term and can result in drug-resistant bacteria. In an effort to develop a drug-free alternative, these researchers hav (Read more...)

Terahertz Spectroscopy to Assess Severity of Skin Burns

Scientists at Stony Brook University in New York have developed a hand-held scanner that uses terahertz time-domain spectroscopy and neural network data analysis to non-invasively assess the severity of skin burns. At present, it is difficult to visually assess the depth of a burn injury, which could negatively influence treatment outcomes. The dev (Read more...)

3D Printed Light Sensor for Light-Sensitive Disease

At the University of Minnesota a team of researchers has developed a 3D printed light sensing wearable that can help people with light-sensitive diseases, such as lupus, to understand more about the types of light that can exacerbate their symptoms. Many people with lupus are sensitive to light, such as sunlight or even regular indoor […]

Tough Ultrasound-Controlled Bioadhesives

Scientists from McGill University in Canada created a technique of using ultrasound-mediated cavitation to make bioadhesives better stick to body’s tissues, including wet surfaces that are typically challenging for such materials. The new method involves ultrasound to create microbubbles within the adhesive. The bubbles burst, which then temp (Read more...)
