At the nanoscale, the properties of materials can differ dramatically from those at larger scales. For example:
Electrical Properties:Nanowires and quantum dots exhibit quantized conductance and discrete energy levels, respectively. Mechanical Properties: Nanomaterials can be significantly stronger and more flexible due to fewer defects. Chemical Properties: Increased surface area enhances reactivity, making nanoparticles effective catalysts. Optical Properties: Nanoparticles can exhibit unique optical behaviors such as surface plasmon resonance.
