What are Tailored Properties?
Tailored properties refer to the specific characteristics of materials that are engineered at the nanoscale to achieve desired behaviors and functionalities. These properties can include mechanical strength, electrical conductivity, optical behavior, and chemical reactivity, among others. By manipulating materials at the nano level, scientists can create substances with novel and enhanced properties not found in their bulk counterparts.
1.
Nanostructuring: Manipulating the structure of materials at the nanoscale, such as creating nanoparticles, nanowires, and
nanotubes.
2.
Surface Functionalization: Modifying the surface of nanomaterials to change their interaction with other substances, which can enhance properties like solubility, biocompatibility, and chemical reactivity.
3.
Doping: Introducing trace amounts of foreign elements into a nanomaterial to alter its electrical, optical, or magnetic properties.
4.
Self-Assembly: Utilizing the natural tendency of molecules to organize themselves into structured arrangements, which can be used to create complex nanostructures with specific properties.
