A group of California scientists has developed small, inexpensive attachments that allow high-definition cellphone cameras to perform microscopy and spectroscopy in the visible region. Although the resolution of the device is not as good as dedicated commercial equipment, it is good enough to distinguish between healthy and diseased blood samples and to detect fluorescent dyes, according to Sebastian Wachsmann-Hogiu of the University of California Davis Medical Center’s Center for Biophotonics, U.S.A.
