APTES模板法合成尺寸可控的空心金納米殼
[Abstract]:Core-shell gold nanomaterials have unique optical properties and have been widely used in many fields such as biochemical analysis medical imaging and clinical treatment. In this paper, the controllable synthesis of gold nanoshell materials was studied. Using the suspension of triaminopropyl triethoxy silane (APTES) as a template and the response of APTES suspension to different gold precursor solutions, a one-pot method (one-potsynthesis) for the preparation of gold nanoparticles was developed. The size of the material and the absorption properties of surface plasmas can be continuously regulated. The colloidal stability and photothermal properties of the materials were systematically studied. The main work includes: (1) controllable synthesis of gold nanoshell. A new method for the synthesis of gold nanoshell materials at room temperature was developed using APTES suspension as template. It was found that adjusting the concentration of tetrachloroauric acid solution could significantly affect the formation of APTES suspensions, and the size of APTES template increased with the increase of the concentration of tetrachloroauric acid. On this basis, a series of gold nanoshell materials with different sizes have been prepared. The surface plasma absorption spectra of the materials are adjustable in the range of 657-957nm, and the synthesis method is simple. At the same time, it was found that the ratio of alcohol to water also had a great influence on the synthesis of gold nanoshell. (2) study on the properties of gold nanoshell. The effects of different ligands on the colloidal stability of the synthesized materials were studied. It was found that the gold nanoshell materials synthesized with bovine serum albumin (BSA) as ligands had good colloidal stability. The photothermal conversion efficiency of gold nanoshells with different sizes was obtained by photothermal conversion experiments. The photothermal conversion efficiency of 37nm gold nanoshells was as high as 45. The cyclic photothermal experiments further proved that the gold nanoshells of different sizes have good photothermal stability.
