“…Aptamers can be easily immobilized on various electrode surfaces by utilizing molecular modification strategies. − The aptamer–protein interactions on the electrode interface can induce electron transfer in the system, resulting in changes in electrical signals such as current, potential and impedance. , As the most direct method for electron transfer characterization, electrical methods can quantify interactions between aptamers and proteins by measuring changes in electrical signals. , Accordingly, numerous electrical methods have been developed, such as differential pulse voltammetry (DPV), alternating current voltammetry (ACV), cyclic voltammetry (CV), square wave voltammetry (SWV), electrochemical impedance spectroscopy (EIS), and amperometric detection. − In this section, we will display various electrical assays based on different detection principles for analyzing aptamer–protein interactions.…”

Serving as the basis of cell life, interactions between nucleic acids and proteins play essential roles in fundamental cellular processes. Aptamers are unique single-stranded oligonucleotides generated by in vitro evolution methods, possessing the ability to interact with proteins specifically. Altering the structure of aptamers will largely modulate their interactions with proteins and further affect related cellular behaviors. Recently, with the in-depth research of aptamer–protein interactions, the analytical assays based on their interactions have been widely developed and become a powerful tool for biomolecular detection. There are some insightful reviews on aptamers applied in protein detection, while few systematic discussions are from the perspective of regulating aptamer–protein interactions. Herein, we comprehensively introduce the methods for regulating aptamer–protein interactions and elaborate on the detection techniques for analyzing aptamer–protein interactions. Additionally, this review provides a broad summary of analytical assays based on the regulation of aptamer–protein interactions for detecting biomolecules. Finally, we present our perspectives regarding the opportunities and challenges of analytical assays for biological analysis, aiming to provide guidance for disease mechanism research and drug discovery.

In combination with the growing fields of artificial intelligence and Internet-of-things (IoT), the innovation direction of next-generation biosensing systems is toward intellectualization, miniaturization, and wireless portability. Enormous research efforts have been made in self-powered technology due to the gradual decline of traditional rigid and cumbersome power sources in comparison to wearable biosensing systems. Research progress on various stretchable self-powered strategies for wearable biosensors and integrated sensing systems has demonstrated their promising potential in practical biomedical applications. In this review, up-to-date research advances in energy harvesting strategies are discussed, together with a future outlook and remaining challenges, shedding light on the follow-up research priorities.
