摘要: A novel hybrid material comprising silver aggregates supported on the porous structure of a free-standing carbon nanotube film was devised and fabricated. This readily allows filtration large volumes fluids, while retaining active analytes so that their characteristic surface-enhanced resonance Raman scattering signals could be registered. The direct identification multiple at attomolar regime achieved through single-molecule spectra.
