Research progress on improvement of conductivity of MOFs and their application in bionsensors: A review

Abstract

Metal organic framework materials (MOFs) have a drawback that limits their wider application: Poor electrical conductivity. In this paper, some research advances in improving the conductivity of MOFs in recent years are reviewed. They are divided into two categories: Intrinsic improvement of conductivity and extrinsic improvement of conductivity. The application of MOFs with improved electrical conductivity in the construction of biosensors is shown. Finally, research trends of improving the conductivity of MOFs and their applications in biosensors are summarized, and promising directions such as the comprehensive application of multiple strategies and the spaceoriented assembly of MOFs are proposed.
