Researchers at University College London have shown that tiny magnetic nanoparticles could enhance cancer treatment. The particles can deliver chemotherapy drugs to cancer cells and also produce a mild heating effect when stimulated with an...
Though immune cells have the capabilities to kill cancer cells, they're often thwarted by cancer's ability to evade detection. Researchers at Pennsylvania State University have now developed engineered natural killer cells that have a much...
When fighting cancerous tumors, all too often the very drugs that can destroy a lesion tend to have significant negative effects on the rest of the body. Doses have to be maintained at moderate levels to avoid side-effects that are even worse...
Researchers at Harvard's Wyss Institute have developed a way to deliver immune-stimulating agents to lung metastases. Their system involves nanoparticles loaded with an immune-stimulating agent that are attached to red blood cells. When injected...
Researchers at the University of Pittsburgh have developed a new antibody-type therapy for SARS-CoV-2, the causative virus for COVID-19. The treatment exploits “nanobodies” – tiny antibody fragments – that are harvested from llama...
Biomedical sensors typically perform their best when they're placed in close proximity to the body. While wearables, such as wrist-worn heart rate monitors, are common these days, they are very limited by where they can be placed on the body,...
Microrobotics researchers have been working for decades, in a seemingly futile attempt, to keep up with the miniaturization that has been achieved in the field of microelectronics. Although rudimentary microscopic robots have been developed,...
Wearable medical devices such as continuous heart rate monitors, insulin pumps, and neural stimulators usually need access to an electric power source in order to function. While there's a great deal of wasted energy that our body emits that...
Electrical stimulation and chemical pharmaceuticals are the two ways that doctors and scientists routinely use to manipulate neural cells. Chemicals have their side effects, are slow to take effect, and are usually systemically delivered, while...
Wet age-related macular degeneration and a number of other eye diseases, including congenital conditions, are related to mutated genes that result in blood vessel abnormalities. These can be treated with gene therapy, but delivering genetic...
Peripheral artery diseases and injuries to tissue reduce the amount of oxygen that reaches the affected muscles. Such ischemia is difficult to treat, as new vessels are required to carry more oxygen into damaged tissues. Stem cells derived from...
