NanoFCM has developed the NanoAnalyzer platform that now enables true flow-cytometry measurement at the sub-micron scale, and down to particle sizes unreachable by any other flow cytometers (10-40nm depending on the nature of the substrate). Nano-flow cytometry, the technology that underpins the NanoAnalyzer, removes bias and uncertainty stemming from the use of fluorescence signal triggering by using its highly sensitive side-scatter channel to trigger particle events. The single-particle nature of the measurement prevents uncontrolled swarming events, reinforcing data integrity. High resolution of both scatter and fluorescence channels allows the assessment of subpopulations, based on size or on bio-chemical properties.
