Aydogan Ozcan, assistant professor of electrical engineering at the University of California, Los Angeles, has developed the CelloPhone—a cell phone attachment that functions as an affordable, portable alternative to the traditional microscope. The CelloPhone, a project out of Ozcan Research Group, can analyze samples of blood, urine, and saliva without a microscope lens. Instead, the device uses the LUCAS--Lens-free Ultra-wide field Cell monitoring Array--platform to analyze samples based on shadow imaging. Instead of imaging bacteria and microbes through a series of lenses that magnify the sample, the device records the shadows of the cells or bacteria in a sample. Images are captured using a special light source and the phone's camera.
