Resonant Sensors Incorporated (RSI) is an Arlington, Texas biotechnology company that builds label-free optical biosensor systems based on its patented guided-mode resonance (GMR) technology. Its ResoSens Ultra-Mab Pro benchtop plate reader and disposable Bionetic microarray plates let researchers watch molecular binding interactions in real time, in a standard 96-well format, using tiny sample volumes and no fluorescent labels. RSI targets antibody discovery, epitope binning, hybridoma screening, kinetics and cell-based assays for immunotherapy, diagnostics and life-science research, and also offers analytical contract testing services.
Zafrens is a San Diego biotechnology company building an ultra-high-throughput single-cell platform that isolates, images, runs assays on, and sequences millions of individual cells per day. Its Z-Screen technology swaps the conventional 96-well plate for a credit-card-sized plastic chip holding 50,000 to 200,000 microwells, each with integrated imaging and multi-omic sequencing. By linking perturbation to genotype, phenotype and function at single-cell resolution, Zafrens compresses multiple stages of drug discovery into a single benchtop experiment - a 500x to 2,000x jump in the number of experiments a scientist can run at one timepoint.
