Nanotechnology is a multidisciplinary field that involves the manipulation and control of matter at the nanoscale. Many principles guide the development and application of nanotechnology, but two key principles are:

1. The principle of bottom-up assembly: This principle involves building complex structures and devices from the bottom up, assembling individual atoms, molecules, or nanoparticles into larger, functional structures. The idea is to use the inherent properties of these building blocks to create structures with specific properties and functions.

2. The Size and Area Principle: This principle recognizes that the properties of materials can change as their size decreases down to the nanoscale. Nanomaterials have a high surface-to-volume ratio, which can result in improved responsiveness, increased strength, and improved electrical and thermal properties. Understanding and exploiting the unique properties of nanomaterials is a key aspect of nanotechnology.
