Characterization of a Keggin Polyoxometalate on Metal and Semiconductor Surfaces
Finally, studies of alpha-[SiW12O40]4- on Si surfaces are undertaken. In the first route, the Si surface is derivatized with a multicationic layer and alpha-[SiW12O 40]4- is assembled on this layer via electrostatic attraction. Characterization of this layer indicates that there is a substantial …

THE ATTACHMENT AND CHARACTERIZATION OF DNA PROBES ON GaAs-BASED SEMICONDUCTOR SURFACES
Immobilization of nucleic acid molecules on solid surfaces is the core of numerous important technologies in the genomics, disease diagnostics and biosensors applications. The architecture and density of immobilized probe molecules depend on the type of the solid surface on which they are anchored. …
