Detection of Covid-19, which continues to show its effect all over the world It gets harder because it has mutations. New species developed by scientists biosensor Thanks to it, the virus will be detected faster than obtaining results from the nose swab or blood sample.
Biosensors that alarm when encountering virus antibodies
Scientists have discovered a new way to detect the proteins that make up the coronavirus and antibodies against it. Virus components or specific Covid-19 They designed protein-based biosensors that emit light when mixed with their antibodies.
Today, most medical laboratories to diagnose this virus and have been replicated so that the genetic material of the virus can be seen. RT-PCR using a technique called. This technique requires specialized personnel and equipment. Antibody testOn the other hand, it reveals whether a person has had COVID-19 in the past. This detection path, which is also used to monitor the spread of the pandemic, also requires complex laboratory supplies and equipment.
Professor of Biochemistry from the University of Wisconsin, who strives to detect the virus directly in patient samples without the need for genetic amplification David baker a research team led by it developed a new device to design new biosensors. This protein based devices recognize certain molecules on the surface of the virus; attaches to them and through a biochemical reaction emitting light.
Head of the University of Wisconsin Department, Baker said, “Simulated version of these new sensors in the laboratory; showed that it can easily detect virus proteins or antibodies in nasal fluid or blood sample” said. Also, “Our next goal is to ensure that they can be used reliably in a diagnostic environment.” said.
