Inexpensive ultrasensitive HIV sensor

Inexpensive ultrasensitive HIV sensor

Researchers at the Instituto de Microelectrónica de Madrid have developed a tiny, cheap, portable sensor potentially capable of detecting HIV in people within a week of infection. Although nucleic acid amplifications is the clinical standard these days, it’s also too expensive for many places around the world. Besides preventing early detection, not being able to screen blood for HIV hinders blood donation efforts. With the development of an immunoassay that combines nanomechanical and optoplasmonic transduction methods, the P24 capsid protein that HIV immunoassays’ looks for can be detected.
