Nano Technology By Dr. Marjan Assefi
Nanotechnology is the branch of technology that deals with the design, manipulation, and application of materials and devices with dimensions in the nanometer scale range (typically between 1 and 100 nanometers). Nanotechnology has been an active field of research for several decades and has led to the development of numerous techniques and applications that have transformed various industries, including electronics, medicine, and energy.
Some recent techniques in nanotechnology include:
DNA origami: This technique involves the use of DNA molecules to create nanoscale structures with precise shapes and sizes. These structures can be used in various applications, such as drug delivery and biosensing.
Carbon nanotubes: Carbon nanotubes are nanoscale cylindrical structures made of carbon atoms. They have unique properties, such as high tensile strength and electrical conductivity, and can be used in various applications, such as electronics and energy storage.
Graphene: Graphene is a two-dimensional material made of carbon atoms arranged in a hexagonal lattice. It has exceptional mechanical, electrical, and thermal properties, and can be used in various applications, such as flexible electronics and water filtration.
Quantum dots: Quantum dots are nanoscale particles that exhibit unique optical and electronic properties. They can be used in various applications, such as solar cells and biomedical imaging.
Nanoparticle synthesis: There are various techniques for synthesizing nanoparticles, such as chemical precipitation, sol-gel synthesis, and laser ablation. These techniques enable the production of nanoparticles with precise sizes and shapes for various applications, such as drug delivery and catalysis.
These are just a few examples of recent techniques in nanotechnology. The field is constantly evolving, and new techniques and applications are being developed all the time.
