Low-dimension Structures

Nanotechnology is a field of science and technology focused on the manipulation of matter at the nanoscale, typically ranging from 1-100 nanometers (nm). This enables the design and fabrication of structures and materials with unique physical, chemical, and biological properties that are not possible with larger scale structures. Low-dimension structures, such as nanowires, nanoparticles, and nanotubes, are important components of Nanobiotechnology and nanodevices used in a wide range of applications, from energy production to medical diagnostics and therapeutics. Nanowires are one-dimensional structures consisting of a single crystal core with a diameter of 1-100 nm. These structures have very high aspect ratios (length/diameter), which enable excellent electrical and thermal conductivity. They have been studied for use in various electronic and optoelectronic devices, including transistors, solar cells, and light-emitting diodes (LEDs). Additionally, nanowires have been used for biosensing and drug delivery applications due to their small size and high surface area. Nanoparticles are two-dimensional structures with diameters ranging from 1-100 nm. These structures have been studied for a variety of applications, including drug delivery, catalysis, and materials science. Nanoparticles possess unique optical, electrical, and magnetic properties that can be tailored to the specific application. For example, they can be used to improve the efficiency of solar cells or create more efficient catalysts.
