New Imaging Technology To Monitor HIV And Malaria Spread Through Cell Phone
Scientists at the University of California, Los Angeles (UCLA) have created a cell phone that can monitor the condition of HIV and malaria patients and test water quality at disaster sites and undeveloped areas.
UCLA electrical engineering professor Aydogan Ozcan has constructed the new innovative imaging technology, which has been miniaturized by researchers in his lab to the point that it can fit in standard cell phones.
The imaging platform, known as LUCAS (Lensless Ultra-wide-field Cell monitoring Array platform based on Shadow imaging), has now been successfully installed in both a cell phone and a webcam. Both devices acquire an image in the same way as using a short wavelength blue light to illuminate a blood, saliva or other fluid sample.
LUCAS captures an image of the microparticles in the solution using a sensor array.
As red blood cells and other microparticles have a distinct diffraction pattern, or shadow image, it becomes easier to identify and count them almost instantaneously by LUCAS using a custom-developed "decision algorithm" that compares the captured shadow images to a library of training images.
Data collected by LUCAS can then be sent to a hospital for analysis and diagnosis using the cell phone, or transferred via USB to a computer for transmission to a hospital.
