The Detection Unit features a thermal chamber optimized for growth of the selected pathogen once sealed in the Bio-Lock™ Detection Tube.

Bio-Lock™ Sampling Swab
Pre-Measured Selective Growth Media
Pathogen specific antibodies conjugated to magnetic and SERS particles
Incubation in Optimized Environment


The Detection Unit deploys SERS technology to monitor pathogen presence and growth.

Reading occurs every 10 minutes during enrichment
Laser interrogates pellet
SERS / Magnetic pellet elicits Raman spectra
Magnet draws particles into pellet


The CERTUS System accurately detects the target pathogen continuously as enrichment is taking place.

The strength of the Raman spectra is proportional to the bacterial load
Specified inflection point triggers alert
Algorithm monitors bacterial presence and growth versus time
