Summary: Electrochemical impedance spectroscopy (EIS) is a sensitive analytical method for surface and bulk properties. Here, we demonstrated redoxless ECS for directly determining surfactant adsorption on screen-printed carbon electrodes (SPCEs), providing excellent capacitance plot loci for quantifying the interfacial permittivity of dielectric layers on electrode surfaces. Our proposed approach may serve as a starting point for future probeless and label-free biosensors based on electrochemistry, eliminating disturbance with surface charge properties and minimizing forced potential bias by avoiding redox couples.

Summary: An antifouling sensing surface was constructed by crosslinking two-dimensional nanomaterial MXene with denatured bovine serum albumin (BSA), and a highly selective antifouling electrochemical biosensor was built. The biosensor, with a large specific surface area and good electrical conductivity, exhibited significantly enhanced sensitivity. Compared with BSA, the hydrogel formed through the peptide chain obtained from BSA provided a better antifouling sensing surface. The prepared biosensor quantitatively detects the concentration of IgG in complex human serum with high sensitivity.

Summary: Biosensors have been widely studied as they offer the possibility of translating standard laboratory methods into small, portable devices. Enzymes are commonly used for determination purposes due to their high selectivity and sensitivity, but their poor shelf-life poses a limitation. This review explores the possibility of using other materials with enzyme-like activity as substitutes for enzymes in point-of-care biosensors. Metal and metal oxide nanoparticles are crucial components in enzyme-less catalytic sensors, but achieving high selectivity and sensitivity remains a challenge. By studying the properties of nanoparticle-based sensors, this review aims to identify the key factors determining their catalytic performance and bridge the gap between fundamental and applied research.

Summary: We present a scalable, fast, and low-cost method for extracting cargo proteins from exosome subpopulations using an alternating (AC) magnetic field to facilitate the mixing of antibody-coated magnetic beads (MBs) with serum samples. By applying this method, we were able to achieve high capture efficiencies of >70% from <50 μL of neat serum in just 30 minutes. This approach, when combined with array-based assaying and a standard duplex electrochemical sandwich ELISA, enabled the detection of sub pg/mL levels of α-synuclein content with excellent precision and a sample-to-answer time of approximately 75 minutes. The high performance and semi-automation of this method hold promise for low-cost Parkinson's disease diagnostics and exosomal biomarker analyses.
