Nanovesicles

Part of speech: noun

Definitions

1. Tiny spherical particles with dimensions measured on the nanometer scale used to transport molecules within biological systems ; minute vesicular structures functioning as carriers of biochemical substances in cells ; extremely small membrane-bound compartments facilitating targeted delivery of materials at the molecular level
2. Nanometer-sized fluid-filled sacs that play roles in intercellular communication or drug delivery ; diminutive vesicles employed to encapsulate and transfer therapeutic agents ; submicroscopic capsules aiding in the efficient movement of bioactive compounds across membranes
3. Microscopically small, membrane-enclosed units instrumental in cellular transport and communication ; nano-scaled vesicular bodies that serve as vectors for molecular transfer and signaling ; minuscule bubble-like structures designed for distributing substances within organisms or synthetic systems

Etymology: "Nanovesicles" is the plural of "nanovesicle", a compound of two parts. The first, "nano-", comes from the Greek "nanos", meaning "dwarf", and entered scientific use as a prefix meaning one billionth (10 to the power of minus nine) of a unit, as in "nanometre" and "nanosecond". The second part, "vesicle", comes from the Latin "vesica", meaning "bladder" or "bubble", and in biology names a small membrane-bound sac inside or around a cell. Put together, the word describes vesicles so small that they are measured on the nanometre scale, typically tens to a few hundred nanometres across. Cells release them to carry proteins, nucleic acids and other molecules between one another, which is why researchers study them closely.

Synonyms: nanoparticles, liposomes, exosomes, microvesicles
