Title: Nanoscale Corals
Description: Image title: Nanoscale Corals.

SEM image of high surface area coral-like gold prepared from a gold-silica nanocomposite.

Coral-like gold nanostructures have been prepared by a newly developed electroassisted codeposition approach. The image’s scale bar is 1000 nm (1 micrometer).

The presented structures are phenomenological. Coral-like gold nanostructures were prepared from silica-gold nanocomposite materials using a newly developed electroassisted codeposition approach. Well-controlled surface area enhancement, thickness and morphology were achieved by manipulating the reaction parameters. The prepared gold nanostructures have high surface areas and nanosized features and thus are ideal materials for many technological applications especially in chemical sensing, biosensing and catalysis. In order to see the resemblance to natural coral, please visit optical images of real corals at http://www.mbgnet.net/salt/coral/animals/cnidar.htm and/or http://state.hi.us/dlnr/dar/coral_reefs.html
