Abstract
Abstract A single nanopore represents a versatile single-molecule probe that can be employed to reveal several important features of proteins, such as physical structure, backbone flexibility, mechanical stability, their folding state, binding affinity to other interacting ligands and enzymatic activity. In this review, we summarize the development and current research related to the field of protein detection by nanopore, as well as a few examples of the pioneer work on protein detection. We first discuss the principle of electrical detection with nanopores and how this technique provides information from current traces. Then the development from peptide detection with biological nanopore to protein detection through solid-state nanopore is described. Finally, we prospect the measurement of protein shape and construction using nanopore technology for the applications in life research area.
