Measuring concentration of nanoparticles in polydisperse mixtures using interferometric nanoparticle tracking analysis (iNTA)

This paper introduces iNTA to measure nanoparticle concentrations in polydisperse mixtures without calibration, validated on known samples and SARS-CoV-2 supernatants.

Interferometric nanoparticle tracking analysis enables label-free discrimination of extracellular vesicles from large lipoproteins

This study applies interferometric nanoparticle tracking analysis to distinguish extracellular vesicles from lipoproteins in plasma and artificial mixtures, showing its superior accuracy over conventional NTA.

Precision size and refractive index analysis of weakly scattering nanoparticles in polydispersions.

This paper introduces iNTA, a method combining interferometric scattering and nanoparticle tracking analysis to precisely measure size and refractive index of nanoparticles in suspensions, demonstrating its application to extracellular vesicles and urine nanoparticles.

The formation of the bacterial RNA polymerase-promoter open complex involves a branched pathway

This study uses single-molecule fluorescence microscopy to show that bacterial RNA polymerase-promoter open complex formation follows a branched pathway with varying stability.
