-
Background: Not only does Gold possess strong size and shape, but may be used to enhance color-based biosensor applications. Colloidal nanoparticles of Gold exhibit localized surface plasmon resonance, resulting in significant scattering and absorption in the visible spectrum.
Description:UCR researchers have developed a film that memorizes stress it experiences through color change. The film captures and records the distribution and amount of pressure between two contacting surfaces by outputting color information. The novel polymer film contains embedded Gold nanoparticles creating a color based on plasmonic interactions. As pressure is applied, the particle spacing changes and in turn changes the color.
