Tuberculosis
Cellscope: There's an App for that
A team of engineers at the University of California at Berkeley are pushing the limits of cell phone technology with the development of their newly minted Cellscope.
The device is a six-inch microscope that attaches to a cell phone’s digital camera lens to take high resolution microscopic images of blood and sputum samples. The Cellscope's compact size and durability makes it ideal for use in the field, nearly eliminating the health worker's need for expensive tabletop microscopes.
The Cellscope team, led by Principal Investigator Dan Fletcher, has been able to reliably identify pathogens from two of the most prominent diseases in the underdeveloped world — malaria and tuberculosis. Combined, the World Health Organization estimates that the two diseases kill 2.7 million people each year, although both are treatable if caught early. (The vast majority of malaria and tuberculosis cases are found in sub-Saharan Africa and Asia respectively.) The Cellscope offers healthcare workers in remote areas a valuable diagnostic tool, aiding in reliable early detection of these two diseases.
Right now the Cellscope is still being tested in the field. But the UC Berkeley team hopes that in time, data captured by the Cellscope will be uploaded to a central database, allowing medical workers to track the spread of diseases more efficiently than ever before.
