Monitoring this information using a wearable...
Many people with diabetes endure multiple, painful finger pricks each day to measure their blood glucose. Now, researchers reporting in ACS Sensors have developed a device that can measure glucose in sweat with the touch of a fingertip, and then a personalized algorithm provides an accurate estimate of blood glucose levels. A hand-held device combined...
by American Chemical Society A wristwatch-like device measures cytokine levels in passive sweat. Credit: Kai-Chun Lin Early in the COVID-19 pandemic, doctors recognized that patients who developed a “cytokine storm”—a surge of pro-inflammatory immune proteins—were often the sickest and at highest risk of dying. But a cytokine storm can also occur in other illnesses, such as...
CALIFORNIA INSTITUTE OF TECHNOLOGY If someone asked you right now how stressed you are, what would you say? A little? A lot? You do not know? Those are all valid responses, but they are not especially useful to researchers and medical professionals because they are subjective and not easily quantified. Nonetheless, in lieu of a...
Researchers from Caltech, Peking University in China, Santa Clara University, and University of California, Los Angeles have developed a new wearable sensor that can detect gout-causing compounds in sweat. The device relies on novel laser-engraved chemical sensors to detect gout-causing compounds uric acid and tyrosine at concentrations much lower than previously possible. Moreover, the same device...
