Synonyms Nanovid microscopy ; Single-molecule methods ; SPT Definition Single Particle Tracking is a microscopy technique whereby the motion trajectories of individual particles or molecules are visualized. Basic Characteristics Single Particle Tracking (SPT) is a fluorescence microscopy technique developed ...

Single-particle tracking (SPT) is a powerful method for analysing these behaviours directly and in live cells. However, SPT is confounded by multiple sources of experimental noise and biases. Interpreting tracks in terms of quantitative models thus remains a challenging task. We start this Primer ...
2.3. Single Particle Tracking experiments Cells were plated on coverslips previously incubated with 0.1 mg/ml poly-L-lysine for 5 min. For a homogenous attachment of the cells, a gentle centrifugation (50g, 7 min) was performed. The CD4 receptors were labeled for 15 min with 0.03 nMbiotin-...
DNA-PAINT based single-particle tracking (DNA-PAINT-SPT) has recently significantly enhanced observation times in in vitro SPT experiments by overcoming the constraints of fluorophore photobleaching. However, with the reported implementation, only a single target can be imaged and the technique cannot ...
Aggregation of casein micelles (CM) was followed with single-particle tracking using fluorescence microscopy. Initial concentrations of up to a mass fraction of 3% (w/w) were studied. A small fraction of the CMs was labelled with Atto 488 fluorescent dye to achieve sufficient dilution to ...
The single particle tracking method, based on observations of the trajectories of individual particles, is compared with methods that characterize the motions of a large collection of particles such as fluorescence photobleaching recovery. Determination of diffusion coefficients or transport velocities either...
To overcome this, here we combine genome editing and single particle tracking (SPT) to quantify and dissect chromatin binding of PRC1 in live mouse embryonic stem cells (ESCs). This reveals that PRC1 is highly dynamic, with a small number of molecules displaying stable binding to chromatin. ...
Single-particle tracking techniques enable investigation of the complex functions and interactions of individual particles in biological environments. Many such techniques exist, each demonstrating trade-offs between spatiotemporal resolution, spatial and temporal range, technical complexity, and information conte...
