Researchers in Michigan have developed a novel nitric oxide sensing device, providing new insight into the causes of diabetic foot ulcers and possible avenues for treatment … Approximately 9 to 26 million diabetic patients around the world develop foot ulcers every year. These ulcers can double the risk of death for diabetic patients and may take up to 120 days to heal. Previous research has suggested that the impaired healing associated with diabetic foot ulcers is caused by unregulated levels of nitric oxide. Measuring live concentrations of this compound has posed a significant challenge due to its highly reactive nature. Previous studies have used nitrite, a stable byproduct, to measure nitric oxide levels indirectly … read more
