Verily tracks medication internally with wearable 'microscope' 
Alphabet’s life sciences division, Verily, and researchers from the University of California, Los Angeles have created a wearable microscope capable of tracking fluorescent biomarkers inside skin to detect cancers and monitor the progression of drugs in patients' bodies. The portability of the device allows cancer patients to track their condition with real-time data analysis and for doctors to track medications and chemicals in isolation; if developed further, the technology could also have other applications.

UCLA and Verily Alphabet's life sciences division , has developed a wearable microscope that could help doctors in the near future. The device is designed to track fluorescent biomarkers inside the skin, a vital tool used to detect certain cancers and to monitor the delivery of drugs inside a person's body. These biomarkers are, essentially, glow-in-the-dark dyes that medical professionals can follow as they journey around your veins.

It's possible to track these currently, but the technology isn't very portable or cost-effective for day-to-day care. By creating a device that can do the same job, but weighs just a tenth of a pound, cancer suffers could keep one strapped to their bicep for real-time tracking of their medication. It works by firing an angled laser at the skin, with the microscope then capturing the illuminated image that's produced afterward.

This data is then sent back to a computer where an algorithm filters out the noise generated by the skin itself. The resulting image can then let doctors track the chemicals in isolation, and if the tech can be developed further, might have several other applications. Slowly, and without much warning, it looks as if Alphabet's life sciences division is pushing hard to get us closer to the future we've been promised by so much sci-fi.
