Abstract

The invention relates to the technical field of array sensors, in particular to a portable graphene electrode array sensor, and aims to solve the problems that an insulating substrate and a graphene material have different lattice constants and thermal expansion coefficients and are lack of catalytic performance, long growth time is needed, defects are formed, and the growth quality and the characteristics and performance of the device are further influenced. The portable graphene electrode array sensor comprises an array circuit board, wherein a plurality of graphene sensor units connected through an array circuit are arranged on the array circuit board, each graphene sensor unit comprises an insulating substrate, an active layer grows epitaxially on each insulating substrate, one or more layers of heterogeneous quantum dot structures epitaxially grow on each active layer, a graphene layer epitaxially grows on the heterogeneous quantum dot structures, and the graphene layer is a three-dimensional graphene nano wall or a two-dimensional graphene film. Different reaction film layers can be modified on the graphene layer according to requirements, and the graphene material is patterned and functionalized, so that multi-dimensional biological signal detection is realized.

Description

technical field [0001] The invention relates to the technical field of array sensors, in particular to a portable graphene electrode array sensor. Background technique [0002] The conventional graphene preparation methods currently developed include: micromechanical exfoliation, pyrolytic silicon carbide (SiC), chemical vapor deposition (CVD) on transition metals and heavy metals, and chemical intercalation oxidation, wherein the CVD method is a macro-preparation method. The most reliable method for higher quality graphene. At present, the CVD method mainly prepares graphene on transition metals. After the graphene growth is completed, in order to meet different application requirements, the prepared graphene needs to be transferred to the corresponding insulating substrate. The transfer process of graphene itself is a complicated and high-cost process. This process is very unfavorable for mass production; at the same time, the introduction of defects and impurities is ine...
