In the light of hope to identify asymptomatic people, US researchers have found that low-cost, low-cost, potential to enable home diagnosis of COVID-19 infection through rapid analysis of small amounts of saliva or blood. We have developed a new test with a sensor. In less than 10 minutes without the involvement of a medical professional.

When connected to an electronic device that supports the sensor, it can wirelessly send data to the user’s mobile phone via Bluetooth technology.

An important part of the global effort to stop the pandemic epidemic is the development of tests that can quickly identify infections in asymptomatic people.

A team at the California Institute of Technology developed this multiplexing test (a test that combines multiple types of data) with a low-cost sensor developed in the laboratory of Andrew and Peggy Cherng, an assistant professor of biomedical engineering. ..

The sensor, named “SARS-CoV-2 RapidPlex,” contains antibodies and proteins that can detect the presence of the virus itself, antibodies made by the body to fight the virus, and chemical markers of inflammation. COVID 19 infection.

“This is the only telemedicine platform I’ve seen that can provide information about three types of data infections with a single sensor,” Gao said in a paper published online, in the December issue of Journal Matter. It will be published in.

“In just a few minutes, you can check these levels at the same time, giving you a complete picture of your infection, including early infection, immunity, and severity.”

Established COVID-19 inspection techniques typically take hours or days to produce results. Gao’s systems are simple and compact, but these technologies also require expensive and complex equipment.

So far, this device has only been tested in the lab using a small number of blood and saliva samples taken for medical research purposes from individuals who tested positive or negative for COVID-19.

Preliminary results show that the sensor is very accurate, but “you need to perform a large test on a real patient, not a laboratory sample, Gao decisively determines its accuracy. I warn you to. “

“Our ultimate goal is really home use,” he said.

“The following year, we plan to mail it to high-risk individuals for home testing. In the future, we may change this platform for other types of home testing.”
