ASME is built with the most modern web standards, which give you a better & more reliable experience.
Dr. Aydogan Ozcan, a professor at UCLA's School of Engineering and Applied Science, has developed a portable smartphone-based device using a 3-D printer that enables the imaging of objects at nanoscale. Weighing less than half a pound, the device can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive lab equipment, and therefore has the potential to bring diagnostic options to the developing world.
