Determining the properties of biomolecules—particularly of proteins—in their natural environment is a critical step in analyzing their functions and elucidating the mechanisms behind cellular and ...

Researchers studying the movement, interactions and microenvironments of intracellular molecules often need to analyze information on the patterns and rates with which molecules diffuse within the ...

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on ...

Recent studies have revealed that within cells of both yeast and bacteria, the rates of diffusion of RNA proteins - complex molecules that convey important information throughout the cell - are ...
