New CRISPR-based COVID-19 Test Uses Smartphone Cameras to Spot Virus RNA

Identifying and isolating individuals who may be contagious with the coronavirus is key to limiting the spread of the disease. But even months into the pandemic, many patients are still waiting days to receive COVID-19 test results.

Medical Exams: There’s an App for That

Your cell phone can already find your car and tell you what song the restaurant is playing. How about an app to screen for eye disease? By coupling the sophisticated imaging capabilities of smart phone cameras with lenses and software for examining the retina, Daniel Fletcher and his students have developed a hand-held, user-friendly version of the optometrist’s ophthalmoscope and are teaming up with clinical collaborators to detect retinal disease caused by diabetes.
