Electrical Properties: At the nanoscale, materials can exhibit quantum confinement, leading to discrete energy levels and altered electrical conductivity. Mechanical Properties: Nanomaterials often demonstrate increased strength and flexibility due to the reduced likelihood of defects. Optical Properties: Nanoparticles can exhibit plasmon resonance, which can be tuned by changing their size and shape. Chemical Properties: Increased surface area enhances the reactivity of nanomaterials, which can be advantageous in catalysis and sensors.
