What is the difference between Nanotechnology Nanochemistry and Nanoengineering?

Nanotechnology is the overarching field that involves the manipulation and application of materials at the nanoscale, typically between 1 to 100 nanometers. Nanochemistry focuses specifically on the chemical properties and processes associated with nanoscale materials, including their synthesis and reactivity. Nanoengineering, on the other hand, involves the application of engineering principles to design and create systems and devices that utilize nanomaterials for practical applications. Together, these fields contribute to advancements in various industries, including medicine, electronics, and materials science.
