One method for visualizing dynamic biological processes is single particle tracking, a localization microscopy method. For this technique to be successful, several factors need to be considered, ...

Single-particle optical sensing (SPOS) was originally developed for the field of particulate contamination analysis. Particles in a liquid suspension flow through a small "photozone", a narrow, ...

Tunable red to green emissions in upconversion nanoparticles allow precise identification of single particles, enabling accurate, long-term multicolor tracking in complex live cell environments.

Inside living cells, molecules are constantly on the move—binding, diffusing, interacting. An international competition, the 2nd AnDi Challenge, has now delivered a systematic comparison of analytical ...
