Present state of MIP-based sensors for SARS-CoV-2

The need for fast, selective, accurate, and cost-effective in situ analysis in various fields like medical diagnosis, environmental, food, or pharmaceutical analysis has pushed the development of biosensors. Due to their fragility, lower stability under harsh conditions such as high/low pH, organic solvents, high pressure, or temperature, the biological recognition elements have been substituted by fully synthetic counterparts like aptamers and molecularly imprinted polymers (MIPs). MIPs have recently found applications for the detection of SARS-CoV-2. Herein we describe the potential and challenge of application in this field.
