A recent study published in the International Journal of Scientific Reports, researchers from Imperial College London have developed a new device for detecting HIV in a USB flash drive that can be detected with a single drop of blood. The existence of HIV, and then the researchers used computers and handheld devices to read the electrical signals generated by the device. This one-time detection method can be used to monitor the condition of HIV patients.

In addition, the technology can help HIV patients in remote areas to manage the disease effectively. The new equipment developed by the researchers is not only very accurate, but also can produce results within 30 minutes; it can monitor the amount of HIV in the blood, which It is essential to reflect the patient's treatment indirectly. Current methods of routinely carrying out viral load in HIV patients often take several days, sometimes even longer, including the time from transporting a patient's blood sample to the laboratory, in many parts of the world. Especially in areas with high HIV-infected areas, routine testing methods are simply unable to meet the disease monitoring needs of everyday patients.

At the same time, current antiretroviral therapy for HIV infection can reduce the virus content in the patient's body to almost zero. However, this therapy will not work in some patients' bodies, perhaps because the HIV virus is produced. The tolerance of the therapy, which may indirectly indicate an increase in the level of virus in the patient's blood. In addition, routine monitoring of HIV levels can help health care teams test whether patients can benefit from therapy, and blocking therapy seems to promote HIV resistance to drugs, a problem that has now become a global threat. A big problem with public health.

The level of HIV virus is not detected by routine HIV antibody testing, and this method only tells patients if they are infected with HIV. Researcher Graham Cooke said that over the past 20 years, HIV therapy has significantly improved the health of many patients, and many patients are able to live like normal people and achieve their expected lifespan. However, monitoring the viral load of the patient's body is critical to predicting the success of HIV therapy, so the detection of HIV load on HIV often requires expensive and complicated equipment to take days, many researchers use this way. To monitor the viral load of HIV patients' bodies, it is now possible to accomplish such a large monitoring task with a small USB flash drive.
