Mobile phone transforming microscope to quickly deal with pathogens

Scientists at the University of California, Los Angeles (UCLA) have recently successfully developed a low-cost "mobile phone microscope," which is expected to replace bulky and expensive optical microscopes and become the leading portable digital diagnostic instrument in the future.

Aydogan Ozcan, an associate professor of electrical engineering at the University of California, Los Angeles, and a member of the Institute of Nanotechnology, used self-designed software and $ 10 off-the-shelf hardware to successfully transform an ordinary mobile phone into a disease. Digital microscope with screening function.

Simply insert the blood sample slide into the phone via the camera sensor and read the hologram in seconds.

The sensor detects the content of the slide and sends a wireless signal to the hospital or regional medical center. Under normal circumstances, the mobile phone can detect abnormal blood cell deformation or white blood cell infection signs.

Ozcan ’s new invention undoubtedly opened a new path for rapid processing of pathogen samples. Bahram Jalali, an applied physicist at UCLA and a professor of electrical engineering, believes that users no longer need to pass through The narrow field of view of the microscope lens performs a mechanical scan of all kinds of details, but uses holograms to capture the information of all cells at the same time. In just a few seconds, you can pull out the culprit of disease in a large number of healthy cells. The retrieval program has also become easy.

It is worth mentioning that the device is especially suitable for remote areas where there are no hospitals, technicians or diagnostic laboratories. Ordinary people can also collect medical information on the spot through mobile phone microscopes, which is especially beneficial for the diagnosis and prevention of malaria.
