| Abstract Scope |
Nowadays, noble metallic nanostructures with unique morphology are widely used as new sensors due to their fascinating properties. Among various shapes, dendritic nanostructures have attracted much attention because of their large surface-to-volume ratio, high sensitivity and special texture with sharp tips and nanoscale junctions. Several methods have been developed to fabricate those specific structures such as electrodeposition, seed-mediated growth or wet chemical method.
The present study deals with a novel approach for a controlled growth pattern-directed organisation of Au flower-like crystals deposited onto stainless steel plates to achieve large-scale functional surfaces. Results seem to offer attractive perspectives for the conception of a MEMS platform, which could detect traces of specific molecules, differentiate them and regenerate after use. In addition, it opens new routes for the qualitative and quantitative detection of very low concentration of absorbed molecules onto nanostructured surfaces incorporated in a microchip. |
