Understanding nanostructures
Nanostructures are characterized by their small size, which grants them distinct physical, chemical, and mechanical properties. At the Nan scale, quantum effects become significant, resulting in altered material behaviours. Nanostructures can exist in various forms, such as nanoparticles, nanowires, nanotubes, and Nano sheets, each with its specific properties and applications [2].
Properties of nanostructures
The properties of nanostructures differ significantly from those of bulk materials due to their high surface-to-volume ratio and quantum confinement effects. These unique characteristics include enhanced mechanical strength, improved electrical conductivity, heightened catalytic activity, superior thermal conductivity, and exceptional optical properties [3]. Nanostructures also exhibit size-dependent phenomena, such as plasmonics, quantum dots, and phonon confinement, which enable precise control over their functionalities.
Fabrication techniques
Several fabrication techniques have been developed to create nanostructures with precision and control. These methods include top-down approaches, such as lithography and etching, where larger structures are progressively reduced to the Nan scale. Bottom-up methods, on the other hand, involve the assembly and manipulation of individual atoms or molecules to build nanostructures. Examples of bottomup techniques include chemical vapour deposition, molecular self-assembly, and colloidal synthesis [4]. Researchers also explore novel techniques like 3D printing at the Nano scale to construct intricate nanostructures.
