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.

Precision medicine aims to transport therapeutic agents, such as molecules, proteins or RNA, to the exact place where they need to act within the body. One of the most promising strategies is the use ...

What is Nanoparticle Tracking Analysis? Nanoparticle Tracking Analysis (NTA) is a powerful technique for characterizing nanoparticles in solution. It combines laser light scattering microscopy with a ...

HIV-1 remodels the spatial organization of its co-receptor, CXCR4, on T cell membranes, showing that viral entry requires receptor clustering rather than simple receptor binding.

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 ...
