The Industry Need and Solution: This comprehensive solution includes a new multispectral fluorescence-based handheld inspection tool for real time detection of saliva and respiratory droplets that may be contaminated with viruses and infections. We call this the Contamination, Sanitation Inspection and Disinfection (CSI-D) system. These respiratory droplets may be deposited on surfaces exposed to human contact such as seating, tables, handrails, fabrics, doors, water coolers, etc. The worst cross-contamination takes place through surfaces. The virus survives for up to 3 to 17 days on surfaces such as metal, ceramics and plastics. That means things like doorknobs, tables, or elevator buttons can be terrible infection vectors. The CSI-D solution includes using the handheld system to identify suspicious areas and then immediately remediating the potential threat (bacteria, virus) with UV light commonly used to disinfect air, water and surfaces. This protects the safety of cleaning staff. If desired, the contamination can be sampled using a swab-based collection system for further inspection purposes, prior to disinfection. These samples can be sent to a laboratory for pathogen analysis. The CSI-D system seamlessly documents traces of contamination videographically, for more detailed follow-up investigation and cross-contamination tracing.
