Tiny
microscope goes with the flow
Position
a series of microscopic pinholes over digital camera pixels and you have
a microscope-on-a-biochip without the bulky lenses of traditional microscopes.
The microscope captures images of cells and microorganisms as they flow
across the chip. The optofluidic microscopy biochip was used to characterize mutant strains of the microscopic worm C. elegans and take images of single cell organisms.
The microscope biochip could be used for medical and biological research.
