New material can protect against resistant bacteria

13/05/2021

Researchers at Chalmers University of Technology, Sweden, have developed a new material that prevents infections in wounds – a specially designed hydrogel, that works against all types of bacteria, including antibiotic-resistant ones. The new material offers great hope for combating a growing global problem.

Wireless, injectable chips use ultrasound to monitor body processes

12/05/2021

Columbia Engineers develop the smallest single-chip system that is a complete functioning electronic circuit; implantable chips visible only in a microscope point the way to developing chips that can be injected into the body with a hypodermic needle.

Microneedle patch delivers antibiotics locally in the skin

11/05/2021

MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers at Karolinska Institutet in Sweden are developing a microneedle patch that delivers antibiotics directly into the affected skin area.

Radiological images confirm 'COVID-19 can cause the body to attack itself'

26/02/2021

Muscle soreness and achy joints are common symptoms among COVID-19 patients. But for some people, symptoms are more severe, long lasting and even bizarre, including rheumatoid arthritis flares, autoimmune myositis or "COVID toes." A new Northwestern Medicine study has, for the first time, confirmed and illustrated the causes of these symptoms through radiological imaging.

Neural network could help clinicians look for pre-cancerous skin lesions

26/02/2021

A neural network system that analyzes photographs can rank and distinguish suspicious, potentially precancerous skin lesions, which can turn into the deadly skin malignancy melanoma if not caught and removed early.

Wearables: skin patch as an all-in-one health monitor

17/02/2021

Engineers at the University of California San Diego have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer's levels of glucose as well as lactate, alcohol or caffeine. It is the first wearable device that monitors cardiovascular signals and multiple biochemical levels in the human body at the same time.

Regenerative medicine: helps the body healing

03/02/2020

Severe wounds heal slowly and leave scars. This is why we have been using regenerative therapies for some time now to accelerate and improve healing. They also help to avoid permanent damage. Still, complex applications like replacing organs or limbs will rather remain vision than become reality for a long time.

Regenerative medicine: creating a new body?

03/02/2020

Regenerative medicine aims to repair the human body after injuries, accidents or major cancer surgery. Unfortunately, we are still not at a stage where this process can achieve optimal results for every conceivable situation. Having said that, various new methods are on the cusp of breakthrough.

Early detection: Tattoo signals cancer – and more

09/07/2018

People who are not ill and do not show any symptoms typically do not visit the doctor. And while most people know that preventive medical checkups for cancer, for example, are important, they still avoid them. They tend to be very hesitant because the doctor might detect a serious illness. In the future, a new type of implant could make it easier to go to a screening test.

A startup makes melanin glow: skin cancer diagnostics with Magnosco

09/04/2018

When a skin lesion is suspected to exhibit malignant changes, it is usually promptly removed. However, not all cases require an excision of the affected tissue. The startup company Magnosco has developed a procedure that uses a laser to support the diagnosis and early detection of malignant melanoma.
