Biosensors as advanced analytical tools have found various applications in food safety, healthcare, and environmental monitoring rapid specific detection of target analytes small liquid samples. Up to now, planar electrochemical electrodes shown the highest potential for biosensor due their simple compact construction cost-effectiveness. Although a number commercially available electrodes, manufactured from materials on different substrates, can be market, high costs single use low reproducibility persist major drawbacks. In this study, we present an innovative, cost-effective approach fabrication that combines lamination 24-karat gold leaves with low-cost polyvinyl chloride adhesive sheets followed by laser ablation. Laser ablation enables creation customizable geometries patterns microlevel resolutions. The developed are characterized cyclic voltammetry impedance spectroscopy, scanning electronic microscopy, 3D profiling. To demonstrate manufacturing biosensing potential, shapes were realized transducing platform applied realization magnetic bead (MB)-labeled biosensors quantitative food-borne pathogens Salmonella typhimurium (S. typhimurium) Listeria monocytogenes (L. monocytogenes).

Abstract The isolation of a single atomic layer graphite, known as graphene, marked fundamental moment that transformed the field materials science. Graphene-based nanomaterials are recognized for their superior biocompatibility compared with many other types nanomaterials. Moreover, one main reasons growing interest in graphene is its potential applications emerging technologies. Its key characteristics, including high electrical conductivity, excellent intrinsic charge carrier mobility, optical transparency, substantial specific surface area, and remarkable mechanical flexibility, position it an ideal candidate solar cells touch screens. durability further establishes strong contender developing robust materials. To date, variety methods, such traditional spectroscopic techniques chromatographic approaches, have been developed detecting biomolecules, drugs, heavy metals. Electrochemical portability, selectivity, impressive sensitivity, offer considerable convenience both patients professionals point-of-care diagnostics. Recent advancements significantly improved capacity rapid accurate detection analytes trace amounts, providing benefits biosensor technology. Additionally, integration nanotechnology has markedly enhanced sensitivity selectivity electrochemical sensors, yielding results. Innovations point-of-care, lab-on-a-chip, implantable devices, wearable sensors discussed this review. Graphical abstract
