Description

technical field [0001] The invention relates to the technical field of one-dimensional nanomaterials, in particular to a spiny magnetic nickel telluride nanowire and a preparation method thereof, a spiny magnetic nickel telluride nanowire with functionalized gold nanoparticles and a preparation method thereof, application. Background technique [0002] Nanostructures such as noble metal gold nanoparticles, gold nanorods, and gold nanowires have broad application prospects as sensitive materials in biochemical sensors, optoelectronic devices, and other fields due to their unique properties in light, electricity, and force. However, gold is expensive. In order to save costs, later studies will decorate gold nanoparticles on the surface of other nanomaterials, hoping to achieve the same sensitive detection effect. [0003] In the early stage, it was mainly research on gold nanomaterials such as gold nanoparticles and gold nanorods. For example, W.R.Yang et al. reported the pr...
