Mobile phones have become one of the most universal pieces of advanced technology in the world, and they are about to become even more vital. Aydogan Ozcan of UCLA has developed a microscope attachment for a cell phone – turning the device into a sort of mobile medical lab. It’s both lightweight (~38g or 1.5 oz) and cheap (parts cost around $10). As described in the journal Lab on a Chip, the cellphone microscope can analyze blood and saliva samples for microparticles, red blood cells, white blood cells, platelets, and water borne parasites.

Now that is some clever voyving.
