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.

A Medical Lab in the Palm of Your Hand

Sure, your cell phone can take pictures and send text messages, but can it detect malaria?

UCLA scientists have found a way to bring medical diagnostic tests to resource-poor areas by transforming cell phones into cheap, portable gadgets that can monitor and detect diseases like malaria and HIV.

As Wired explains:

UCLA researcher Dr. Aydogan Ozcan images thousands of blood cells instantly by placing them on an off-the-shelf camera sensor and lighting them with a filtered-light source (coherent light, for you science buffs). The filtered light exposes distinctive qualities of the cells, which are then interpreted by Ozcan's custom software. By analyzing the cell types present in a much larger sample, a more accurate diagnosis can be made in a matter of minutes.

Currently, the software to analyze these images runs on a desktop computer, but Ozcan’s team is working to create software that runs on the cell phone device itself.

This technology is still in developmental stages, and skeptics are already lighting up online discussion boards. But the promise of quick, accurate and low-cost blood testing in the world's most remote areas is definitely exciting. And if this idea does become a widespread reality, here’s hoping that effective treatment for those diagnosed follows quickly on its heels.
