MChip
mChip is a portable blood test device which is capable of diagnosing an infection of HIV or Syphilis within 15 minutes and could be used effectively against HIV/AIDS in developing countries. The mChip costs about US$ 1 and the entire diagnostic kit costs about US$ 100. mChip was developed so that people in regions with poor health facilities can access portable diagnosis for HIV/AIDS rather than travelling long distances to go to clinics for diagnosis.
