This is a list of notable computer programs that are used to model nanostructures at the levels of classical mechanics [1] and quantum mechanics. Furiousatoms [2] - a powerful software for molecular modelling and visualization; Aionics.io [3] - a powerful platform for nanoscale modelling; Ascalaph Designer; Atomistix ToolKit and Virtual NanoLab ...
Due to this, acoustics are especially widely used in the biomedical industry to manipulate droplets, cells and other molecules. Acoustic waves are generated by a piezoelectric transducer controlled from the pulse generator. These waves are able to then manipulate droplets of liquid and move them together, in order to form a packed assembly.
Lithography techniques can also be used to controllably manipulate the diameter and position of the droplets (and as you will see below, the resultant nanowires). One-dimensional crystalline nanowires are then grown by a liquid metal-alloy droplet-catalyzed chemical or physical vapor deposition process, which takes place in a vacuum deposition ...
The tip of a scanning probe can also be used to manipulate nanostructures (positional assembly). Feature-oriented scanning may be a promising way to implement these nano-scale manipulations via an automatic algorithm. [56] [57] However, this is still a slow process because of low velocity of the microscope.
The top-down approach is breaking down of a system into small components, while bottom-up is assembling sub-systems into larger system. [15] A bottom-up approach for nano-assembly is a primary research target for nano-fabrication because top down synthesis is expensive (requiring external work) and is not selective on very small length scales, but is currently the primary mode of industrial ...
Liquid phase exfoliation is different from other liquid exfoliation methods, for example the production of graphene oxide, because it is much less destructive, leaving minimal defects in the basal planes of the nanosheets. It has recently emerged that LPE can also be used to convert non-layered crystals into quasi-2D nanoplatelets. [12]
Solvent vapor annealing (SVA) is a widely used technique for controlling the morphology and ordering of block copolymer (BCP) films. [1] [2] [3] By controlling the block ratio (f = NA/N), spheres, cylinders, gyroids, and lamellae structures can be generated by forming a swollen and mobile layer of thin-film from added solvent vapor to facilitate the self-assembly of the polymer blocks.

The wettability of a polymer surface at the nanoscale [1] [10] has been modified, and nanostructures of poly(p-phenylene vinylene) (an electroluminescence conjugated polymer) have been created. [11] Nanoscale templates on polymer films for the assembly of nano-objects such as proteins and DNA have also been created [ 12 ] and crystallization of ...
