Philadelphia-based biotech company LIV Process unveiled a new “microbial visualization” technology at IDWeek 2025 that lets healthcare workers see pathogens like Clostridioides difficile on surfaces without a microscope. The patented solution binds to spores and makes them fluoresce under a specific light, helping hospitals evaluate cleaning effectiveness in real time and improve infection prevention. The company says this tool fills a gap in current hygiene practices and is being validated with major health systems.
