The ARC additionally combines MRPS with single-particle fluorescence detection (F-MRPS), enabling simultaneous measurement of fluorescent subpopulations — such as payload-loaded LNPs or labeled EVs — in up to three optical channels. The nCS2 provides fast, accurate size and concentration measurements without fluorescence capability.”","sourceUrls":["https://nanoparticleanalyzer.com/faq/"]}]}
