Enhanced Strength: Nanomaterials often exhibit superior mechanical properties such as
high tensile strength and hardness. For example, carbon nanotubes are known to be stronger than steel while being lighter.
Increased Chemical Reactivity: Due to their high surface area, nanomaterials can have increased chemical reactivity. This property is particularly useful in
catalysis and chemical sensing applications.
Unique Optical Properties: Nanomaterials can exhibit unique optical properties such as
surface plasmon resonance (SPR). Gold nanoparticles, for example, can change color based on their size and shape.
Electrical Conductivity: Some nanomaterials exhibit extraordinary electrical conductivity. Graphene, a single layer of carbon atoms, is known for its excellent electrical conductivity and flexibility.
Magnetic Properties: Nanomaterials can exhibit unique magnetic properties that are size-dependent. For instance,
superparamagnetism is observed in nanoparticles of magnetic materials, making them useful for data storage and medical applications.
