We describe the development and application of nanosensors having bioreceptor
probes for bioanalysis. The nanoprobes were fabricated with optical fibers
pulled down to tips having distal end sizes of approximately 30–60 nm. The use
of two different types of receptors was investigated. Fiberoptic nanoprobes were
covalently bound either with bioreceptors, such as antibodies, or with other
receptors,... hiện toàn bộ
Polymer-protected silver microclusters have been obtained by room-temperature
alcoholic reduction of metal ions in presence of a polymeric stabilizer (i.e.,
poly(N-vinyl-2-pyrrolidone) (PVP)). The method allows one to prepare bulk
quantities of the material with a control of size from a molecular level.
Spectrophotometric monitoring technique has been employed to investigate the
influence of the a... hiện toàn bộ
