ProbiusDx

ProbiusDx is a private healthcare and life-science tools company developing a bioanalytical platform based on Quantum Electrochemical Spectroscopy (QES). The company positions QES as a label-free, reagent-free electrochemical sensing and machine-learning platform that converts small biological samples into high-dimensional digital signatures, or "digital twins," for downstream analysis. Its MiniQES system and cloud software are aimed at biomarker discovery, analyte quantitation, preclinical research, bioproduction quality control, and other bioanalysis workflows rather than drug development. ProbiusDx appears to commercialize instrumentation, consumables, and analytics services for pharma, biotech, and research users, while also running a collaborative QESLab program to generate application data and external validation. The company is focused on enabling broad-spectrum biological measurement from minimal sample volumes with simplified workflows.
