Abstract

The invention discloses a novel metal cup-cylinder composite nano structure array which is formed by sequential arrangement of metal nano structure array units. The metal nano structure array units are of a metal cup-cylinder composite nano structure which comprises a cup-shaped metal nano outer wall, and the center of a cup groove formed by the metal nano outer wall is a cylindrical metal nano particle. The invention also discloses a preparation method of the metal nano structure array, and the preparation method comprises the processing steps of preparing a single-layer orderly polrvinyl benzene nano ball compact arrangement, preparing a single-layer orderly polrvinyl benzene nano ball non-compact arrangement, preparing a nano annular-structure array mask made of composite materials, preparing a silicon-nano-structure array template, preparing the metal cup-cylinder composite nano-structure array, and the like. The metal nano array structure provided by the invention has gaps with smaller nano sizes and can be used for realizing the Roman detection of a single biomolecule; and according to the preparation method, the compatibility is good, the efficiency is high and the cost is low.

Description

technical field [0001] The invention relates to the field of metal nanostructures, in particular to a composite nanostructure array and a preparation method thereof. Background technique [0002] In recent years, metal nanostructure arrays with nanoscale gaps have excellent optical properties due to the plasmon resonance generated by the collective excitation of free electrons on the surface, so they are used in optical filters, plasmonic optical waveguides, biological / chemical Sensors, substrate materials for surface-enhanced spectroscopy and other fields have a very wide range of application values. Among them, the size of the nanoscale gap directly affects the sensitivity and other properties of the nanosensor. The establishment of a controllable nanogap structure and corresponding characterization technology has become one of the key foundations for the development of ultra-high-sensitivity nanosensors and molecular devices. [0003] At present, most of the "top-down" o...
