Spectradyne has developed and commercialized a revolutionary method of measuring sub-micron nanoparticles called microfluidic resistive pulse sensing, or MRPS. This technology allows for direct and accurate measurement of nanoscale particles on a single-particle basis, unlike other commonly used characterization techniques. Spectradyne continues to innovate, and has now combined the ease and accuracy of MRPS with single-particle fluorescence detection to create fluorescence microfluidic resistive pulse sensing, or F-MRPS. This new adaptation of MRPS allows for accurate subpopulation analysis, surface marker/target quantification, payload quantification, and much more.

Applications include characterizing nanomedicine delivery systems such as lipid nanoparticles and extracellular vesicles, the measurement of protein aggregation in the drug development industry, virology, consumer product quality control, and many others.

The goal at Spectradyne is to provide easy-to-use nanoparticle characterization tools with unparalleled accuracy to enable better science, and to foster new discoveries.
