Scientists at UCLA's California Nano Systems Institute have molded a mobile phone into a portable blood tester capable of monitoring diseases like HIV, malaria, leukemia and other infectious disease.Sony Ericsson mobile phone has been molded into a LUCAS imager. LUCAS is a selective acronym for Lensfree Ultrawide-?eld Cell-monitoring Array platform based on Shadow imaging.
A new MacGyver-esque cell phone hack could bring cheap, on-the-spot disease detection to even the most remote villages on the planet.
Blood test today requires either refrigerator-sized machines that cost tens of thousands of dollars or a trained technician who manually identifies and counts cells under a microscope.
But the new invention just uses a LED, plastic light filter and some wires, these systems are cheap and require dedicated labs to function. And soon they could be a thing of the past.
UCLA researcher Dr. Aydogan Ozcan image thousands of blood cells instantly by placing them on an off-the-shelf camera sensor and lighting them with a filtered-light source. The filtered light exposes distinctive qualities of the cells, which are then interpreted by Ozcan's custom software.
By analyzing the cell types present in a much larger sample, a more accurate diagnosis can be made in a matter of minutes.
The bulge on the back is the filtered light source that illuminates the sample. This low-cost hack could revolutionize disease detection in the field.
