Scientists turned Nokia Lumia 1020 into a DNA scanner
Nokia Lumia 1020 smartphone announced in 2013 was equipped with one of the best cameras in the market with a record resolution of 41 megapixels, optical stabilization and xenon outbreak. Manufacturers have long completed the megapixel race, but it is too early to throw the development of the Finnish brand to the landfill of history. At the University of California at Los Angeles, a portable microscope for DNA research was created on the basis of a camera. It allows you to analyze far beyond the laboratory.
How did they do it
For the first time about this invention it became known back in 2015, but then Nokia Lumia 1020 was mentioned simply as a smartphone on Windows Phone. Scientists printed the optical-mechanical basis of the microscope on the 3D printer, and the gadget camera became its central element. The analysis is carried out according to the fluorescent method. Two laser diodes make DNA molecules emit light, and a bright white LED is used as a backlight.

Having involved machine learning algorithms, using such a microscope, you can diagnose cancer diseases. For example, the authors of development have successfully examined the tumor of the large intestine. The scanner is compared with a tricoder from the Star Way, with the help of which the heroes of the series could remotely diagnose.
There are analogues?
Google has been working on such a device since 2013, but for all this time the search giant has not shown a single prototype. The ISS uses an Oxford Nanopore portable analyzer worth $ 500, although experts have doubts exactly its measurement. Whether a new microscope works with less resolution mobile cameras, scientists do not report.
