Ion beam nanoengineering of surfaces for molecular detection using surface enhanced Raman scattering
Publikováno v:
Molecular Systems Design & Engineering. 7:411-421
Ion beam engineering of surfaces is a promising way to tailor the surface properties. It provides control over depth and concentration of nanoparticles for SERS applications.

We demonstrate a method for engineering substrates for surface enhanced Raman spectroscopy (SERS) by Ag− ion implantation in Si. The implantation dose and beam current density are chosen such that the Ag concentration in Si exceeds the solid solubi

We report capping of silicon (Si) nanocrystals (NCs) via xylene attachment to the surface of oxide etched, luminescent, core/shell nanostructures of Si/Si-oxide in colloidal suspension. The core/shell nanostructures of Si/Si-oxide are formed by contr

The Raman effect is typically observed by irradiating a sample with an intense light source and detecting the minute amount of frequency shifted scattered light. We demonstrate that Raman molecular vibrational resonances can be detected directly thro

A new technique in microscopy is demonstrated in which the domain of Atomic Force Microscopy (AFM) is extended to optical spectroscopy at the nanometer scale. Molecular resonance of feature sizes down to the single molecular level were detected and i
