Bompart et al. [125] reported the synthesis of composite nanoparticles of approximately 500 nm diameter consisting of a polymer core, a layer of gold nanoparticles attached to the core, and a few nanometers thick MIP outer layer (Fig. 13). These particles were used as individually addressable nanosensors, where surface-enhanced Raman spectroscopy was used to detect the binding of the target analyte, the beta-antagonist propranolol. A l,000x improved detection limit was...

Fourier-Transform Infrared (FTIR) spectroscopy as well as Raman spectroscopy are well established as methods for structural analysis of compounds in solution or when adsorbed to surfaces or in any other state. Analysis of the spectra provides information of qualitative as well as of quantitative nature. Very recent developments, FTIR imaging spectroscopy as well as Raman mapping spectroscopy, provide important information leading to the development of novel materials. If applied under optical near-field conditions, these new technologies combine lateral resolution down to the size of nanoparticles with the high chemical selectivity of a FTIR or Raman spectrum. These techniques now help us obtain information on molecular order and molecular orientation and conformation [1],...

Silver and gold nanoparticles were generated electrochemically and investigated with confocal Raman microscopy. The combination of surface-enhanced Raman spectroscopy with confocal microscopy accompanied by subsequent scanning electron microscopy provided an image of the geometrical stmcture of the Raman spots.

Raman spectroscopy can be used to detect normal modes of target molecules and also to monitor spectra of Raman labels that are used for one of the spectroscopic bar-codes. Raman bands in the vibrational Raman spectmm have intrinsically narrow bandwidths of ca. 10 cm, which, for example, correspond to less than 0.5 nm width in the visible region below 800 nm. The fluorescence of dye molecules has a broad bandwidth of 100 nm more or less. Hence, spectral overlap between fluorescence bands is inevitable and limits their use for multiplexed analysis. Quantum dots (QDs) have narrower bandwidth than dye-based fluorescence but stUl have broad bands that are several tens of nanometers. Light scattering of noble metal nanoparticles caused by surface plasmon resonance is also...
