Nanomanufacturing refers to manufacturing processes of objects or material with dimensions between one and one hundred nanometers. [15] These processes results in nanotechnology, extremely small devices, structures, features, and systems that have applications in organic chemistry, molecular biology, aerospace engineering, physics, and beyond.

Schematic representation of the different stages and routes of the sol–gel technology. In this chemical procedure, a "sol" (a colloidal solution) is formed that then gradually evolves towards the formation of a gel-like diphasic system containing both a liquid phase and solid phase whose morphologies range from discrete particles to continuous polymer networks.
These results suggest that inorganic nanomaterials, in general, may be better reinforcing agents compared to carbon nanotubes. Another kind of nanocomposite is the energetic nanocomposite, generally as a hybrid sol–gel with a silica base, which, when combined with metal oxides and nano-scale aluminum powder, can form superthermite materials.
Two of the most common alternatives to PLD synthesis are described below: Cellulose nanofibers (CNF) were constructed into nanofoams by: [28] (i) Recycled milk container board was pretreated with deep eutectic solvent (DES) to fibrillate it. (ii) The pretreated board was put through a simple freezing drying procedure to form a nanofoam shape.
New foods are among the nanotechnology-created consumer products coming onto the market at the rate of 3 to 4 per week, according to the Project on Emerging Nanotechnologies (PEN), based on an inventory it has drawn up of 609 known or claimed nano-products. On PEN's list are three foods—a brand of canola cooking oil called Canola Active Oil ...
Fullerene – any molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or tube. Fullerene spheres and tubes have applications in nanotechnology. Allotropes of carbon – Aggregated diamond nanorods – Buckypaper –
These products were limited to bulk applications of nanomaterials and did not involve atomic control of matter. Some examples include the Silver Nano platform for using silver nanoparticles as an antibacterial agent , nanoparticle -based sunscreens, carbon fiber strengthening using silica nanoparticles, and carbon nanotubes for stain-resistant ...
Nanomaterials can also be used in three-way-catalyst applications, which have the advantage of controlling the emission of nitrogen oxides (NO x), which are precursors to acid rain and smog. [45] In core-shell structure, nanomaterials form shell as the catalyst support to protect the noble metals such as palladium and rhodium. [46]
