Abstract

Temporal analytical techniques to track nanoparticles in live cell would provide rich information to well understand the biologic properties of nanoparticles in molecular level. Significant advances in fluorescence microscopy techniques with high temporal and spatial resolution allow single nanoparticles to label biomolecules, ions, and microstructures in live cells, which will address many fundamental questions in cell biology. This review highlights the real time tracking techniques for monitoring the movement of nanomaterials such as carbon nanotubes (CNTs), quantum dots (QDs), metal clusters, upconver-sional nanomaterials, and polystyrene (PS) nanoparticles etc. in live cells. The biological properties of nanoparticles in live cells are also briefly summarized according to fluorescence microscopy studies. The technique to track nanoparticles would provide rich information to well understand their behaviors in live cell, this because such techniques could disclose the nanoparticles in high spatial resolution in situ. This review highlights these techniques and their applications in monitoring the nanoparticles in live cells, and the biological properties of nanomaterials are summarized according the temporal techniques.
