A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

(a) The specific structure of a natural biological cell membrane, which owns an ultrathin structure and a dual hydrophilic-hydrophobic character. (b) Interface strain as the driving force to curl the ...

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.
