Antibody screening-assisted multichannel nanoplasmonic sensing chip based on SERS for viral screening and variants identification.

The Omicron variants of SARS-CoV-2 have been spreading globally and have never disappeared from our sight, indicating that their coexistence with humans has become a fact, and monitoring its evolution and spread remains a current task.
