Western-Massachusetts based angel network River Valley Investors (RVI) has completed an investment in QSM Diagnostics.

QSM Diagnostics provides the only diagnostic instrument-sensor method for identifying and monitoring biomarkers produced by common bacteria in ear pus. In under 2 minutes, electronic sensors are used to detect the unique quorum sensing molecules that each bacteria produces and secretes. Their Pseudomonas sensor has been shown to be effective in pre-clinical human and animal studies, as well as with initial dog ear swabs.

This is River Valley Investors’ first investment in ApprentiScope.

River Valley Investors is the premier angel investor group in western Massachusetts.
