Abstract :

An important number of applications has arisen reporting the use of nobel metal nanoparticles (NPs) as optical markers in single-molecule assays, as molecular rulers, as local orientation- or sensitive biochemical- nanosensors and enhance Raman scattering of surface-bound molecules (SERS). Assembly of several NPs has also been used to develop scalable fabrication of new nanodevices, just by playing with a controlled coupling chemistry. However, this rational clustering of two NPs (dimers or hot-spots with high electromagnetic enhancements in SERS application) by solutions methods has been a notable challenge, since nanoassembly�´s dissociation or aggregation must be avoided during performance or application. In this talk, we will present our alternative approach based on a postsynthetic purification method which ahs overcome this difficulty yielding highly desirable optical SERS active nanoassemblies for nanosensors.
