A UCLA researcher worked on a hack to a cellphone which can image blood cells instantly using off-the-shelf camera sensor, an LED as filtered light source and custom software.
This new invention has potential to help proliferate affordable testing devices for various field conditions including those in developing countries.
Quoted Wired news:
“A new MacGyver-esque cellphone hack could bring cheap, on-the-spot disease detection to even the most remote villages on the planet. Using only an LED, plastic light filter and some wires, scientists at UCLA’s California NanoSystems Institute have modded a cellphone into a portable blood tester capable of monitoring HIV, malaria, leukemia and detecting diseases.”
