Microscope On A Chip

Researchers at Caltech recently developed a revolutionary new type of microscope without lenses. The device is compact enough to be put in a cell phone and can use just sunlight for illumination. This makes it very appealing for Third-World applications,

Bioengineers Develop 'Microscope On A Chip'

ScienceDaily (July 29, 2008) — Researchers at the California Institute of Technology have turned science fiction into reality with their development of a super-compact high-resolution microscope, small enough to fit on a finger tip. This "microscopic microscope" operates without lenses but has the magnifying power of a top-quality optical microscope, can be used in the field to analyze blood samples for malaria or check water supplies for giardia and other pathogens, and can be mass-produced for around $10.
