Scientists and researchers from the Center for Research and Advanced Studies (Cinvestav) Monterrey Unit, of the National Polytechnic Institute (IPN), the Optical Research Center (CIO) Aguascalientes Unit, and the Yucatan Scientific Research Center (CICY), They are developing a microchip that helps detect COVID-19 in 30 minutes. Currently the results of tests that are carried out to determine if a person infected with the virus takes up to 24 hours.
The instrument would perform a blood test to determine if the body has been exposed to certain microorganisms, and as a result will find antibodies (immunoglobulins) produced by the body specifically when a person is infected with COVID-19. This is a serological test.
The technology has microchannels, which are the diameter of the size of a hair, through which the serum obtained from the patient's blood sample will be introduced, which through a biosensor will recognize the antibodies produced for the coronavirus.
Subsequently, this sample will be incubated for 20 minutes, washed and placed in a special molecule, from which they will obtain a fluorescent signal that will indicate if the person is infected.
The microchip is expected to deliver the results in half an hour, however it will need to be validated with a large number of samples.
The cost of this test would be low, since the researchers donate their time to perform it. Although it is not possible to calculate it for these conditions, it is expected that its price will be 90% lower than the cheapest pregnancy test performed in Mexico, according to information from Milenio .
