Smartphone attachment detects viruses and bacteria

Researchers at UCLA have developed a portable smartphone attachment that can be used to perform field testing to detect viruses and bacteria.

This cellphone-based imaging platform could be used for specific and sensitive detection of sub-wavelength objects, including bacteria and viruses and therefore could enable the practice of nanotechnology and biomedical testing in field settings and even in remote and resource-limited environments,’ Aydogan Ozcan, professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, said in a statement.

Using this device, which attaches directly to the camera module on a smartphone, Ozcan’s team was able to detect single human cytomegalovirus (HCMV) particles.
