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, ...

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.

Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their blueprint—the genetic information. Here, the basic building blocks of proteins, ...

Milk-derived extracellular vesicles (mEVs) are promising drug carriers because they can survive the digestive tract, be engineered to avoid immune rejection, and deliver therapeutic cargo to the body.

Neutrino detectors, particle calorimeters and some dark matter detectors require dense and massive active materials. An extremely fine segmentation is desirable to achieve precise three-dimensional ...

NTA mainly uses the principle of scattering of light by a particle to locate it in real-time. The particle movements are tracked, and the size is measured using a high-speed video recording. 2 A laser ...
