What is Rational Design?
Rational design refers to the methodical approach of designing molecules, materials, or systems with specific properties and functions. In the context of
nanotechnology, it involves the precise manipulation and control of matter at the nanoscale to achieve desired outcomes. This interdisciplinary field combines principles from chemistry, physics, biology, and engineering.
Why is Rational Design Important in Nanotechnology?
Rational design is crucial in nanotechnology because it enables the creation of nanomaterials and
nanodevices with tailored properties. This approach helps in addressing critical challenges in various sectors, including medicine, electronics, energy, and environmental science. By understanding and controlling nanoscale interactions, scientists can develop materials with enhanced performance, such as increased
efficiency, durability, and functionality.
Key Principles of Rational Design
