What is Covalent Synthesis?
Covalent synthesis refers to the method of creating nanomaterials by forming strong covalent bonds between atoms. This process is fundamental in
Nanotechnology for constructing stable, highly-functional materials at the nanoscale. Covalent synthesis is generally employed to produce
nanomaterials with specific properties tailored for applications in electronics, medicine, and energy.

Chemical Vapor Deposition (CVD):
CVD is widely used to produce
carbon nanotubes and other nanomaterials. It involves the decomposition of a precursor gas to form a thin film of material on a substrate.
2.
Sol-Gel Process:
This method involves the transition of a system from a colloidal solution (sol) to a solid (gel) phase. It is useful for creating
nanoparticles and thin films.
3.
Self-Assembly:
Molecules spontaneously organize into stable, well-defined structures through covalent bonding. This approach is highly effective for creating
molecular nanostructures.
