Abstract

The invention provides a shape of a nano array on the surface of an anodic alumina film, a method for controlling the shape growth of the nano array on the surface of the anodic alumina film in a nano-confined space, and an application of the nano array on the surface of the anodic alumina film. The shape of the nano array on the surface of the anodic alumina film comprises an alumina film and a nano array on the surface of the alumina film, wherein the nano array is a ZIF-8 nanopore array with uniform structural distribution, the pore depth is 60+/-5 mum, and the pore depth-to-width ratio is(4.7+/-3) x 103. The invention further provides the application of the nano array on the surface of the anodic alumina film in biophysics, biochemistry, ion detection, researches in intermolecular interaction, catalysis and separation, energy storage, and other fields. The shape, the method and the application provided by the invention have the advantages that a synthesis method is simple and lowin cost; the shape can be easily observed and detected; and an obtained nanomaterial is stable in structure and physicochemical property, and is recyclable.

Description

technical field [0001] The invention relates to the field of nanomaterials, in particular to the morphology of nano arrays on the surface of anodic aluminum oxide films and a method and application for controlling the growth of the morphology in a nano-confined space. Background technique [0002] Since the conjecture of nanopore DNA sequencing was put forward in the 1990s, solid-state nanopores with stable pore size and good physical and chemical properties have become the research objects of biophysics and biochemistry. Through the internal modification of the channel, the functionalized solid-state nanopore has performed well in biosensing such as studying the interaction between biomacromolecules, disease diagnosis, drug delivery, ion detection, and deciphering the structure and function of biomacromolecules. test performance. In the future, the application of nanopores in life sciences will be broadened, and nanopore technology will definitely have a profound impact on...
