Scientists develop fluorescent dye-loaded nanosized, irregularly-shaped microplastics to track their movement in real time.

Harmless, fluorescent proteins allow scientists to track blood flow in mice. The advance could help researchers monitor and understand disease progression. The corresponding study was published in ...

Accurately modeling irregularly-shaped particles isn’t easy, but a new study found a way to improve a century-old idea.

An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...

Go with the flow: tracing 1-micron-diameter fluorescent particles using the twin-Airy-beam technique produces a 3D map of blood flow in a zebrafish. Each colour represents a different particle. The ...
