A nanoprobe as existing in the real world is an optical device. It was developed by tapering an optical fiber to a tip measuring 100 nm = 1000 angstroms wide. Also, a very thin coating of silver nanoparticles helps to enhance the Raman scattering effect of the light. (The phenomenon of light reflection from an object when illuminated by a laser light is referred to as Raman scattering.) The reflected light demonstrates vibration energies unique to each object (samples in this case), which can be characterised and identified. The silver nanoparticles in this technique provides for the rapid oscillations of electrons, adding to vibration energies, and thus enhancing Raman Scattering -- commonly known as surface-enhanced Raman scattering (SERS). These SERS nanoprobes produce higher electromagnetic fields enabling higher signal output--eventually resulting in accurate detection and analysis of samples.
