Abstract

The MAESTRO instrument is a recent development that enables sensitive, spatially located, microbial detection using deep UV spectroscopy at a standoff distance up to 5m. This capability stems from prior deep UV fluorescence/Raman standoff instruments for point chemical, biological, and explosives analysis, as well as from planetary science in the form of the SHERLOC instrument on the Mars 2020/Perseverance Rover, a deep UV fluorescence/Raman mapping robotic arm-mounted instrument looking for signs of life on Mars. The MAESTRO instrument leverages these detection capabilities to enable microbial detection on environmental/natural surfaces with high-speed mapping rates with map areas <1m2 . This talk will discuss the fundamentals of the methodology for detection, the achieved sensitivity, and the analytical approach used to detect and differentiate microbial hazards from the background.
