A new faction has joined in the war against malaria: graduate students. A group of students developed a malaria diagnostic tool that will be rolled out in India and Ethiopia this summer.  Called, the Lifelens project, the tool uses a micro lens on the camera of mobile phones that can ultimately test for and diagnose malaria.

Created by Harvard Business School student Cy Khormaee and UC Davis doctoral student Wilson To, the lifelens product attaches a $50 micro lens to the camera of a Windows 7 enabled smartphone.

With the camera in place, the phone can then capture high-resolution images of the cells in a drop of blood that is placed on the micro lens. Windows 7 software quickly analyzes the images, confirming the presence or absence of malaria. Once the images are analyzed, the results can be sent to public health workers and other health professionals via SMS for further assessment and data collection.

Current standard practices in malaria diagnosis involve administering a rapid diagnostic test (RDT). This method takes a blood sample, usually off of the finger of the patient, and then exposed to a cotton swab containing a solution that reacts with malaria antigens that may be in the blood. However, this method is inefficient and produces many false positives, with only a 40% accuracy rate.

The lifelens tool acts as a powerful microscope and can easily be sterilized for further immediate usage. It is also more accurate than RDT since it detects malaria cells directly. To and Khormaee say that in the long run, the lifelens tool will be more cost effective than current RDT detection methods.

However, there are some obstacles. The lifelens tool only operates on a Windows 7 enabled smartphone. These phones cost hundreds of dollars and may be affordable in resource poor areas. Also, the lifelens tool is not the only novel technological tool in the malaria detection space. Disposable tests are already in wide use, and others are developing diagnosis technologies, including a DNA-based one that could, like Lifelens, test for malaria and other illnesses.

The lifelens project received an award in the Microsoft sponsored Imagine Cup competition that featured innovative technological tools that use Microsoft software. With this award in hand, To and Khormaee plan to roll out a testing phase for their tool in India and Ethiopia.

Virtually all deaths from malaria occur in the developing world with 90% occurring in Africa. Any advancement in malaria diagnosis is highly valued. The lifelens project is aiming to change the way infectious disease diagnosis is handled. “Malaria is just the beginning,” says To. “We’re building a platform.”
