Abstract A method for the detection of procalcitonin (PCT) with improved accuracy is urgently needed. A dual-mode electrochemical immunosensor with CuCo2S4–Au bimetallic sulfides as enhancer for accurate detection of PCT was fabricated in this work. The immunosensor not only displays a heavy square wave voltammetry (SWV) signal due to the electron transfer of Cu2+ and Cu+ but not the addition of electron mediators. But also presents high electrocatalytic activity towards H2O2 redox reactions and...

Abstract Preeclampsia (PE) is a pregnancy-specific hypertensive syndrome recognized as the leading cause of maternal and fetal morbidity and mortality worldwide. Painful blood-collection procedures or low accuracy of noninvasive approaches require faster, patient-friendly, and more sensitive diagnostic technologies. Here we report a painless, highly sensitive detection platform using nanoporous microneedles (nMNs) that enables rapid capture of biomarkers present at sub-nanogram levels. The highl...

Abstract The continually growing use of glyphosate and its critically discussed health and biodiversity risks ask for fast, low cost, on-site sensing technologies for food and water. To address this problem, we designed a highly sensitive sensor built on the remarkably specific recognition of glyphosate by its physiological target enzyme 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSPs). This principle is implemented in an interferometric sensor by using the recently established soft colloida...

Abstract Electrochemical immunoassay (ECIA) is an important method for rapid, on-site detection of various analytes. However, its detection sensitivity is greatly limited by the traditional sandwich-type sensor construction mode, especially in the case of large-size targets such as pathogenic bacteria with micron size. Herein, we developed a Faraday cage-type sensing mode to build an electrochemical immunosensor based on a functionalized two-dimensional conductive nanomaterial, which could provi...

Abstract Herein, we report a novel lateral flow immunoassay (LFIA) system for detecting cardiac troponin I (cTnI) in serum using the time-resolved fluorescence resonance energy transfer (TR-FRET) technique and the fusion 5 membrane. The fusion 5 membrane is used as a strip for LFIA, and it is constructed without additional matrices (such as a sample or conjugation pad). Although this strategy for constructing the LFIA strip is quite simple and cost-effective, LFIA is still not suitable for the a...

Abstract Cardiac arrhythmia and drug-induced cardiotoxicity seriously threaten the human life. To develop antiarrhythmic agents and prevent the drug-induced cardiotoxicity, it is demanded to explore the high-specificity and high-efficiency drug screening platforms for preclinical investigations. Here, a specific electromechanical integrated correlation (EMIC) model was established based on the synchronized signal recording of cardiomyocyte-based biosensing system. The cardiomyocyte-based biosens...

Abstract Microbial extracellular electron transfer (EET) stimulates a plethora of intellectual concepts leading to potential applications that offer environmentally sustainable advances in the fields of biofuels, wastewater treatment, bioremediation, desalination, and biosensing. Despite its vast potential and remarkable research efforts to date, bacterial electrogenicity is arguably the most underdeveloped technology used to confront the aforementioned challenges. Severe limitations are placed ...

Abstract COVID-19 pandemic outbreak is the most astounding scene ever experienced in the XXI century. In this opinionated review, we underscore the crucial role of biosensing to handle with such situations. As a matter of fact, testing accelerates life-saving decisions on treatment and isolation of COVID-19 patients in an early stage, and thereby, decelerating or even preventing the spread of such emerging infectious diseases. Meanwhile, it is also proven that a timely and broad application of t...

Abstract Cancer cells alter their metabolism to promote rapid proliferation, resulting in significant amounts of glucose to be used for aerobic glycolysis in the tumor microenvironment. Due to the spatial mismatch between electrodes and cells, existing methods for evaluating cancer cell metabolism lack kinetic and microenvironmental information. In this paper, we present a hollow fiber structure loaded with sensing elements as a long-term cellular metabolism monitoring platform. The unique gradi...

Abstract To break the “Black-Box” status of the wound healing process under traditional dressing, which cannot achieve satisfactory repair outcome of skin wounds, a wound healing system with the abilities of pro-regeneration and real-time monitoring of wound status has become a considerable necessity. Here, by integrating the emerging bioelectronics and software, we created a flexible wound healing system. The hardware system was designed as Band-Aid shaped with a double-layer structure; the upp...
