Brazilian researchers develop a biosensor adapted to diagnose covid-19.

Researchers at the São Carlos Institute of Physics (IFSC) develop biosensors capable of diagnosing covid-19, by inserting a DNA sequence (deoxyribonucleic acid) capable of identifying the covid-19 virus into an existing biosensor. 

The developed biosensors comprise three main components: (i) a recognition biomolecule capable of specifically interacting or capturing the target of the analysis; (ii) a device or transducer for converting a target-bioreceptor biological event into a measurable signal; and (iii) equipment to process the quantifiable signal output.

Biosensors are defined as devices capable of detecting the concentration or presence of a target using biomolecular probes, biologically derived or biomimetic materials. 

The researchers are looking for partners to couple the biosensor to portable measuring equipment and to implement large-scale production.
