Functionalization of GRMs with specific biomolecules for the sensing of SARS‐CoV‐2. GRMs derivatization can be done either before or after the deposition onto the substrates. Most of the sensing events described so far include the interaction of a specific biomolecule with functionalized GRMs. The first attempts mainly included sensors with electrical readout, yet other outputs (e.g., spectroscopic signal) are foreseen.
