What are Tailored Nanomaterials?
Tailored nanomaterials are engineered at the nanoscale to exhibit specific properties and functions. These materials are designed to leverage the unique characteristics that emerge at scales typically less than 100 nanometers, such as increased surface area, quantum effects, and enhanced chemical reactivity. This precision allows for the creation of materials with customized physical, chemical, and biological properties that can be applied in various fields.
How are Tailored Nanomaterials Created?
Creating tailored nanomaterials involves several techniques, including
bottom-up synthesis and
top-down fabrication. Bottom-up synthesis builds materials atom by atom or molecule by molecule, often via chemical vapor deposition or self-assembly processes. Top-down fabrication, on the other hand, starts with bulk materials and scales them down using methods like lithography or etching.
