Atomic Scale Technology - Nanotechnology

What is Atomic Scale Technology?

Atomic scale technology refers to the manipulation and control of matter at the atomic and molecular level. This area of science and engineering operates on a scale of less than 100 nanometers, allowing for the creation of materials and devices with unprecedented precision and novel properties.

How is Atomic Scale Technology Related to Nanotechnology?

Nanotechnology is the application of atomic scale technology to create new materials, devices, and systems with unique properties and functions. By understanding and manipulating matter at this scale, scientists can develop innovations in a wide range of fields including medicine, electronics, and materials science.

What are the Key Techniques Used in Atomic Scale Technology?

Several advanced techniques are employed in atomic scale technology, including:

Scanning Tunneling Microscopy (STM): Allows for imaging and manipulating individual atoms on a surface.
Atomic Force Microscopy (AFM): Measures forces between a sharp probe and the surface to image and manipulate matter at the nanoscale.
Electron Beam Lithography: Uses focused beams of electrons to draw custom shapes on a surface with nanometer precision.
Molecular Beam Epitaxy (MBE): Enables the deposition of atomic layers to create high-quality crystalline structures.

What are the Applications of Atomic Scale Technology in Medicine?

Atomic scale technology has transformative potential in medicine, particularly in areas such as:

Drug Delivery: Nanoparticles can be engineered to deliver drugs directly to targeted cells, reducing side effects and improving efficacy.
