What they work on

  1. Develop a disposable microchip that selectively detects HIV-1 directly from whole blood samples, rather than detecting antibodies against the virus.
  2. Make the self-test sensitive enough to detect HIV below 1,000 copies per milliliter. This would allow it to catch acute infection in the first weeks and viral rebound in patients on antiretroviral therapy.
  3. Engineer the assay to be fully automated (sample-in, answer-out), to give results within 40 minutes, and to stay stable without refrigeration.

More about the research

Today's HIV self-tests detect antibodies, proteins the body makes against the virus. These appear only three to four weeks after infection, so the tests miss new infections. They also cannot show when treatment is failing. Antiretroviral therapy (ART), the standard drug treatment for HIV, keeps the virus in check, but monitoring requires testing that most self-tests cannot provide. No self-test on the market can detect the virus itself during the first two weeks after infection, the acute phase. None can detect viral rebound, when the virus returns in a patient on ART.

Why it matters

An affordable self-test that detects HIV within weeks of infection and flags treatment failure could help people learn their status sooner and help patients on ART know when their virus is returning. Because the device would need no refrigeration, it could widen testing access in places where lab-based viral load monitoring is unavailable. It could also support HIV treatment programs worldwide, where ART coverage remains about 59%.
