Optofluidic Microscopy (OFM)

Optofluidic microscopy (OFM) is a new compact and lensless microscopic imaging technique invented in our lab. It abandons the conventional microscope design, which requires expensive lenses and large space to magnify images, and instead utilizes microfluidic flow to deliver specimens across array(s) of micrometer-size apertures defined on a metal-coated CMOS sensor to generate direct projection images. The size of our OFM prototype device is as small as a US quarter, and yet can render images comparable in quality to those of a microscope with 20X objective.
