During this past 2021, the research group has developed different types of sensors to detect SARS-CoV-2 virus in saliva. The first one was a photoelectrochemical aptasensor and the second one was based on the MIP (molecular imprinted polymer) technique. Both works have been led by Mahmoud Amouzadeh Tabrizi in the framework of his CONEX-Plus project. These sensors are capable of detecting the SARS-Cov-2 virus in a saliva sample in a matter of minutes with greater sensitivity and specificity than antigen-based sensors, and faster and cheaper than PCR tests. These new sensors can be incorporated into portable, easy-to-use diagnostic systems.
