Lensless fluorescence detection system provides highly sensitive water quality assessment

Researchers have shown that a fluorescence detection system that doesn't contain any lenses can provide highly sensitive detection of deadly microorganisms in drinking water. With further development, the new approach could provide a low-cost and easy-to-use way to monitor water quality in resource-limited settings such as developing countries or areas affected by disasters. It could also be useful when water safety results are needed quickly, such as for swimming events, a concern highlighted during the Paris Olympics.

New technique tracks blood sugar with light

Diabetes is a very prevalent disease that, unfortunately, still has no treatment. People with diabetes need to monitor their blood glucose levels (BGLs) regularly and administer insulin to keep them in check. In almost all cases, BGL measurements involve drawing blood from a fingertip through a finger prick. Since this procedure is painful, less invasive alternatives that leverage modern electronics are being actively researched worldwide.
