What is Nanotechnology?

Nanotechnology is the science, engineering, and application of materials and devices with structures sized between 1 and 100 nanometers. At this scale, materials often exhibit unique physical and chemical properties that are leveraged for a variety of applications. The field is inherently interdisciplinary, combining aspects of Physics, Chemistry, Biology, Materials Science, and Engineering.

How does Physics contribute to Nanotechnology?

Physics plays a crucial role in understanding the fundamental principles that govern the behavior of materials at the nanoscale. Phenomena such as quantum mechanics, electron tunneling, and surface plasmon resonance are central to the design and application of nanomaterials. Techniques like scanning tunneling microscopy and atomic force microscopy are essential tools that physicists use to visualize and manipulate nanoparticles.

What is the role of Chemistry in Nanotechnology?

Chemistry is vital for the synthesis and functionalization of nanomaterials. Chemical methods such as sol-gel processes, chemical vapor deposition, and self-assembly enable the creation of nanoparticles with specific properties. Chemists also study the surface chemistry of nanomaterials to enhance their reactivity and compatibility for various applications, including drug delivery and catalysis.

What biological applications are there in Nanotechnology?

Biology intersects with nanotechnology primarily in the field of nanomedicine. Nanoparticles are being designed for targeted drug delivery, where they can deliver therapeutic agents directly to diseased cells, minimizing side effects. Additionally, biosensors that use nanomaterials can detect biological markers at extremely low concentrations, improving the early diagnosis of diseases. The study of nanotoxicology is also crucial to understand the safety and environmental impact of nanomaterials.
