The technique involves measuring brain waves using an EEG cap while a person watches a screen with a series of flashing images. Taking just two minutes, the test quantifies a person’s ability to differentiate between images based on […]

Microneedle Patch Delivers Oxygen to Chronic Wounds

A team of scientists at Purdue University created a microneedle patch that can deliver oxygen and bactericidal agents to chronic wounds. The bacterial biofilms that form over non-healing wounds, such as foot ulcers, are a formidable barrier to successful treatment. Such wounds are typically hypoxic and the bacteria within them are shielded from antibiotics within […]
