Taking a closer look with a lens-free fluorescent microscope
Lenses are no longer necessary -- at least, not in the research world -- according to Rice University engineers developing FlatScope, a thin fluorescent microscope whose abilities promise to surpass those of old-school devices. The engineers' recent study describes a wide-field microscope as thin as a credit card, small enough to sit on a fingertip and capable of micrometer resolution over a volume of several cubic millimeters. The researchers claim that FlatScope, an advance on the earlier FlatCam, could be used as an implantable endoscope, a large-area imager or a flexible microscope.
