Scientists develop new cell phone-based tool to detect HIV
Recently, scientists have developed a low-cost and portable diagnostic tool by utilising a nanotechnology and cell phone, which can detect HIV. It can also monitor its management in resource-limited regions.
According to the Hindustan Times report, management of human immunodeficiency virus 1 (HIV) remains a major global health challenge in developing countries that lack infrastructure and trained medical professionals. This is a serious disorder that cripples the immune system by attacking healthy cells.
Hadi Shafiee from Brigham and Women’s Hospital in the US report said that early detection of HIV is critical to prevent disease progression and transmission, and it requires long-term monitoring, which can be a burden for families that have to travel to reach a clinic or hospital. She also added that this rapid and low-cost cell phone system represents a new method for detecting acute infection, which would reduce the risk of virus transmission and could also be used to detect early treatment failure.
According to the study published in the journal Nature Communications, traditional virus monitoring methods for HIV are expensive, requiring the use of polymerase chain reaction (PCR).
An affordable, simple tool has been designed by Shafiee and his colleagues that makes HIV testing and monitoring possible for individuals in developing countries with less access to medical care.
The researchers said the total material cost of the microchip, phone attachment and reagents was less than USD 5 per test.
Mohamed Shehata Draz from Brigham and Women’s Hospital reportedly said that we could use this same technology as a rapid and low-cost diagnostic tool for other viruses and bacteria as well. This platform could help a lot of people worldwide.
