Here is a wearable microscope that can detect and monitor fluorescent biomarkers inside the skin for medical diagnostics and tracking biochemical reactions. It weighs less than one-tenth of a pound and could prove useful for cancer detection and drug delivery.
The microscope uses a laser to hit the skin at an angle. It captures images and sends them to a computer for processing. As Aydogan Ozcan, UCLA’s Chancellor’s Professor of Electrical Engineering and Bioengineering explains:
We can place various tiny bio-sensors inside the skin next to each other, and through our imaging system, we can tell them apart … We can monitor all these embedded sensors inside the skin in parallel, even understand potential misalignments of the wearable imager and correct it to continuously quantify a panel of biomarkers.
The research was published in the journal ACS Nano.
