Abstract
Surface enhanced resonance Raman spectroscopy (SERRS) can be used in analytical science to identify target molecules at very low concentrations. The combination of this method with other techniques such as magnetic manipulation or electrochemistry allows constructing new analytical devices that exhibit several functionalities. In the talk, the author will show several examples of such multifunctional SERRS Hybrid devices. In the first example the use of [email protected] 2 and [email protected] chitosan nanoparticles for selective detection and separation of target proteins in a mixed sample is demonstrated. In the second example Fe 3 O 4 @Ag-Myoglobin nanoparticles are presented that are capable of detecting and magnetically removing small toxic molecules in water. Fe 3 O 4 @TiO 2 -Ag nanoparticles are used in the third example to detect, collect and catalytically decompose toxic pollutants. Here also the positive effect of plasmonic Ag nanoparticles on photocatalytic degradation is discussed. The last example demonstrates how SERRS spectro-electrochemistry is able to get insight into the functionality of enzymatic biosensors.
