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.

The measurement of particles in cell therapy production has long presented challenges, particularly since the drug product itself is composed of particles, compounding the complexities in the process.

Aim: This study examines the absolute quantification of particle uptake into cells. Methods: We developed a novel method to analyze stacks of confocal fluorescence images of single cells interacting ...

Stem cells are particularly interesting for researchers as they are initially undifferentiated and differentiate into specialized cells over time. In recent years, significant research has been ...
