What the tool is doing

Dynamic fluorescent holotomography is presented as a multimodal live-cell imaging method for investigating nanoparticle uptake, subcellular trafficking, and cargo delivery. The abstract describes it as combining label-free holotomographic imaging with intermittent fluorescence readouts.

Source 1DOI PubMed

Resources required

The described workflow requires integrated holography and tomography and uses intermittent fluorescence microscopy. The quantitative library application also uses fluorescently tagged lipid- and polymer-based nanoformulations.

Source 1DOI PubMed

What problem it solves

It addresses technological limitations that have made it difficult to study nanoparticle-cell interactions, uptake mechanisms, and trafficking kinetics over long time windows. It also enables quantitative uptake characterization without adding cell or organelle markers.

Source 1DOI PubMed

What it does not solve

The abstract does not show that the method eliminates the need for fluorescent nanoparticle tagging in all use cases, because the library characterization is described for fluorescently tagged nanoformulations.

Source 1DOI PubMed

Alternatives

The abstract contrasts this method with approaches that rely on cell or organelle markers. It also frames intermittent fluorescence microscopy as a complementary modality rather than a replacement.
