Abstract

The invention discloses a gold-silver nanoflower and a preparation method and application thereof. The gold-silver nanoflower is a gold-silver nanomaterial coated with polylysine, and the preparation method of the gold-silver nanoflower comprises the steps of: mixing polylysine with a gold source, and then sequentially mixing with a silver source and a reducing agent for reaction to obtain the gold-silver nanoflower. According to the invention, the gold-silver nanoflower material with good biocompatibility and high physical and chemical stability can be obtained through a one-pot green synthesis method. The synthesis method has the advantages of simple steps, greenness, safety, high efficiency, rapidness and capability of implementing mass production.

Description

technical field [0001] The invention belongs to the technical field of composite nanoparticle preparation, and in particular relates to a gold and silver nanoflower and its preparation method and application. Background technique [0002] Nanomaterials have unique optical, thermal, and electrical properties, and have been widely used in various fields, such as sensors, optoelectronic materials, photothermal therapy, and biological imaging. Studies have shown that the performance of nanomaterials largely depends on the shape, structure, size and composition of materials, so it is of great significance to study nanomaterials with special morphology. Among them, noble metal nanomaterials are favored by scientists because of their tunable local surface plasmon resonance effect. The special morphology of anisotropic gold nanomaterials often has the field effect of the tip or the void in the particle, which makes the plasmon resonance absorption peak redshift to the near infrared...
