Tunable red to green emissions in upconversion nanoparticles allow precise identification of single particles, enabling accurate, long-term multicolor tracking in complex live cell environments.

Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their blueprint—the genetic information. Here, the basic building blocks of proteins, ...

(Nanowerk Spotlight) The field of drug delivery has long been challenged by the need for precise, targeted methods to transport therapeutic agents within the body. Traditional approaches often ...

Using a precisely aligned pair of laser beams, scientists can now hold a single aerosol particle in place and monitor how it charges up. The particle’s glow signals each step in its changing ...
