Biocatalytic Metal-Organic Frameworks for Applications in Electrochemical Sensing

Abstract

Metal-organic frameworks (MOFs) are a class of functional porous three-dimensional framework materials exhibiting unique chemical properties, which are constructed through the self-assembly of organic ligands and metal centres. Owing to the harmonisation of functionality and porosity, extensive research has been conducted into MOFs, including for applications as analysis and catalysis materials. Concurrently, significant progress has also been achieved in the advancement of electrochemical sensors. This work presents the design of MOF/MOF hybrid materials (pristine MOF and MOF hybrid material) and the newly developed methods in preparing and constructing electrochemical sensor systems based on MOFs. The problems and the limitations in MOF electrochemical sensors are also discussed. We also briefly discuss the future scope and direction of electrochemical sensors based on MOFs.
