Structures found on meteorite fragment Allan Hills 84001. Nanobacterium (/ ˌ n æ n oʊ b æ k ˈ t ɪər i əm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌ n æ n oʊ b æ k ˈ t ɪər i ə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally ...
A nanobe (/ ˈ n æ n oʊ b, ˈ n eɪ n oʊ b /) [1] is a tiny filamental structure first found in some rocks and sediments.Some scientists hypothesize that nanobes are the smallest form of life, 1 / 10 the size of the smallest known bacteria.
For example, by adding this peptide to pyruvate decarboxylase and alcohol dehydrogenase, researchers have engineered an ethanol bioreactor. [102] Strategies for encapsulating proteins into synthetic shells using various adaptor domains [ 103 ] and fusions to termini of shell proteins [ 104 ] have also been successful.
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes).

For example, L-forms of the rod-shaped bacterium Bacillus subtilis appear round when viewed by phase contrast microscopy or by transmission electron microscopy. [8] Although L-forms can develop from Gram-positive as well as from Gram-negative bacteria, in a Gram stain test, the L-forms always colour Gram-negative, due to the lack of a cell wall.
Microfauna (from Ancient Greek mikros 'small' and from Latin fauna 'animal') are microscopic animals and organisms that exhibit animal-like qualities and have body sizes that are usually <0.1mm. [ 1 ] [ 2 ] Microfauna are represented in the animal kingdom (e.g. nematodes , small arthropods ) and the protist kingdom (i.e. protozoans ).
A nanostructure is a structure of intermediate size between microscopic and molecular structures. Nanostructural detail is microstructure at nanoscale. In describing nanostructures, it is necessary to differentiate between the number of dimensions in the volume of an object which are on the nanoscale.
The most important objectives that are frequently found in nanobiology involve applying nanotools to relevant medical/biological problems and refining these applications. Developing new tools, such as peptoid nanosheets, for medical and biological purposes is another primary objective in nanotechnology. New nanotools are often made by refining ...
