Figure 1 Rayleigh light-scattering of metallic nanostructures of different sizes and shapes. This example shows the simplicity of creating structures with unique properties, simply by changing the structure’s dimensions.

Figure 2 Schematics of nanostructures integrated with biological molecules and structures. A, Schematic of a semiconductor nanostructure called quantum dots (sphere) with a protein on its surface. This quantum dot/protein system can be used for labeling cells, biosensing, or detecting tumors. Adapted with permission [10] from the National Academy of Sciences, © 2004. B, Schematic of a nickel nanostructure bound to an F1-adenosine triphosphatase biomolecular motor. The motor is a mechanical device to power up and direct the nanostructure. One day, these motors may be important components in building nanodevices for in vivo biomedical applications such as cancer treatment.
