What is Nanotechnology?
Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale. It involves the design, production, and application of structures, devices, and systems by controlling shape and size at the nanometer scale (1 to 100 nanometers).
Why is Ease of Fabrication Important?
The ease of fabrication is crucial in nanotechnology because it determines the feasibility of scaling up from laboratory research to real-world applications. Simplified and cost-effective fabrication techniques can significantly impact the
economic viability and widespread adoption of nanotechnological innovations.
Top-down approach: Techniques like lithography and etching to create nanoscale patterns.
Bottom-up approach: Self-assembly and chemical vapor deposition for building structures atom by atom or molecule by molecule.
Molecular Beam Epitaxy (MBE): A method for creating high-purity crystalline materials.
Electrospinning: A technique to produce nanofibers from polymer solutions.
Material Properties: The physical and chemical properties of materials determine the suitability of various fabrication methods.
Process Complexity: Simpler processes are generally more scalable and cost-effective.
