(ScienceDaily, April 23, 2010) — Aydogan Ozcan, whose invention of a novel lensless imaging technology for use in telemedicine could radically transform global health care, has now taken his work a step further ― or tinier: The UCLA engineer has created a miniature microscope, the world’s smallest and lightest for telemedicine applications. The microscope, unveiled in a paper published online in the journal Lab on a Chip, builds on imaging technology known as LUCAS (Lensless Ultra-wide-field Cell Monitoring Array platform based on Shadow imaging), which was developed by Ozcan, an assistant professor of electrical engineering at the UCLA Henry Samueli School of Engineering and Applied Science and a researcher at UCLA’s California NanoSystems Institute. Instead of using a lens to magnify objects, LUCAS generates holographic images of microparticles or cells by employing a light-emitting diode to illuminate the objects and a digital sensor array to capture their images. The technology can be used to image blood samples or other fluids, even in Third World countries. “This is a very capable and yet cost-effective microscope, shrunk into a very small package,” Ozcan said. “Our goal with this project was to develop a device that can be used to improve health outcomes in resource-limited settings.” Click here to read more…
