Four-dimensional multi-particle tracking in living cells based on lifetime imaging
Nanophotonics, 2022 Research on dynamic events in living cells, such as intracellular transportation, is important for understanding cell functions. As movements occur within cells, the microenvironment of the moving vesicles or biomacromolecules may affect the behavior of ...

Tracking single particles for hours via continuous DNA-mediated fluorophore exchange
Nature Communications, 2021 The length of single-particle tracking experiments are limited due to photobleaching. Here the authors achieve long-term single-particle tracking with continuous fluorophore exchange in DNA-PAINT and use this to observe DNA origami on lipid bilayers for ...

Single-Particle Tracking Porcine Epidemic Diarrhea Virus Moving along Microtubules in Living Cells
Proceedings, 2020 Porcine epidemic diarrhea virus (PEDV), a member of the genus Alphacoronavirus, has caused severe damage to the swine industry. Although viruses are believed to hijack the microtubule-based transport system, the exact manner of PEDV moving along ...

Single-Particle Tracking of Human Lipoproteins [PDF]
Analytical Chemistry, 2015 Lipoproteins, such as high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very-low density lipoprotein (VLDL), play a critical role in heart disease. Lipoproteins vary in size and shape as well as in their apolipoprotein content. Here, we developed a new experimental framework to study freely diffusing lipoproteins from human blood ...

Targeted single-particle tracking with upconverting nanoparticles
ACS Applied Materials & Interfaces, 2023 Abstract Single-particle tracking (SPT) is a powerful technique to elucidate the behavior of biomolecules inside or on the surface of living cells in real time. SPT is based on labeling the component of interest with a phosphor or a light-scattering gold nanoparticle, and visualizing its motion by real time microscopy.

Trajectory data of antero- and retrograde movement of mitochondria in living zebrafish larvae
Data in Brief, 2020 Recently, a large number of single particle tracking (SPT) approaches have been developed. Generally, SPT techniques can be split into two groups: ex post facto approaches where trajectory extraction is carried out after data acquisition and feedback ...

The single particle tracking system [PDF]
SPIE Proceedings, 2010 In an optical tweezers system, the force measurement with a resolution less than pico-Newton can be achieved by precise measurement and analysis of the trapped particle trajectory. Typically, this single particle tracking technique is realized by a quadrant position sensor which detects the scattering lights of the trapping laser beam from the ...
