Research on Covid-19 is underway throughout the world. The knowledge recently brought to light by the University of Maryland School of Medicine is surprising. Though the entire thing is still in the experimental phase. This time, however, the coronavirus can be seen in 10 minutes with the naked eye, not under a microscope.

In other world countries like India, the lockdown has been eased in order to revive the economy. Corona infections are thus on the rise worldwide. The virus spreads really quickly during this period. The experiment was invented by the School of Medicine at the University of Maryland to detect the virus' presence within a short time. Experiments reportedly used a particular molecule that binds itself to gold nanoparticles for the first time. This helps to identify a particular protein in the compound. That makes it very easy to find out about the virus' genetic sequence. Recently, the investigators published the entire method in the ACS Nano Journal.
How does this test work?
To perform this test no microscope or instrument is needed. Second, saliva should be taken from the patient. The gold nanoparticles in the sample are then turned into a mixture. If this mixed solution turns blue the patient should be understood to have a virus in his body. And if the color does not change or it transforms into a purple mixture, then it should be known that there is no Saras-Cove-2 virus present. And if the color does not change or it transforms into a purple mixture, then it should be known that there is no Sars-Cove-2 virus present.
"Based on our preliminary findings, we conclude that this new test can detect the RNA of the virus," said Dipanjan Pan, a UMSM professor of diagnostic radiology and nuclear and pediatric medicine, according to a press release issued by UMSM. However, a couple of tests are needed to confirm this further.
How different is it from other tests for coronavirus?
This method is quicker than any other test. This is because the traditional RT-PCR test requires specialized laboratory research. That is not necessary in this case. The RNA virus was first converted, by reverse transcription, to DNA in the PCR test.Copying the DNA is then multiplied by the sum. It takes 9 to 10 hours to get the report through PCR testing. And then, it takes about a day to use so many methods to do the whole thing with the sample. This is because the family of the virus is often recognized when taking saliva samples. The remainder of the study is then performed only if it belongs to the novel coronaviruses family.
