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, ...

What do cells want to be when they grow up, and how do they get there? Intrigued by these questions, many developmental biologists try to follow the journeys of cells from when they can virtually ...

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.

Single-cell analysis is a ubiquitous laboratory technique that allows researchers to probe the myriad biomolecular states of cells. Single-cell assays can reveal gene and protein expression patterns, ...

Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers. (Nanowerk ...
