Materials that exhibit different physical properties resulting from changes at the nanoscale have already opened the door to many new applications. Many of these applications are still in various stages of research, but some are already available commercially.
For example, clothing material has been integrated with nanoparticles to create stain resistant cloth. Auto manufacturers enhanced bumpers with nanocrystals, making them stronger. Color filters and colored lamps have been created by altering the optical properties of a suspension (through varying of the size and shape of the colloidal particles in the solution). Carbon nanotubes have been designed for products such as bike frames and tennis rackets to enhance strength and reduce weight.
