There are several techniques to tailor the properties of nanomaterials:
1. Size and Shape Control: The physical properties of nanomaterials, such as optical and electronic properties, can be significantly altered by controlling their size and shape. For example, gold nanoparticles exhibit different colors based on their size due to surface plasmon resonance.
2. Surface Modification: The surface chemistry of nanomaterials can be modified to improve their compatibility with other materials or to introduce new functionalities. This can be achieved through coating, functionalization with specific molecules, or doping with other elements.
3. Composition Adjustment: Changing the composition of nanomaterials can tailor their properties. For instance, alloying different metals can produce nanoparticles with unique catalytic properties.
