Abstract

The near real-time detection of airborne particles of interest is needed for avoiding current and future threats. The incorporation of imprinted particles into a micelle-based electrochemical cell was shown to produce a signal when brought into contact with particle analytes (such as SARS-COV-2) previously imprinted onto the structure. Nanoamp scales of signals were generated from what appeared to be single virus-micelle interactions. The system was shown to have selectivity to the imprinted particles over others that are of similar size and configuration. The liquid-based technology was shown to be compatible with airborne aerosol sampling techniques. Overall, the application of imprinted micelle technology can provide near real-time detection methods to a host of possible analytes of interest in the field.
