This symposium aims to explore the latest developments in biosensing, particularly in complex sample matrices. The program emphasizes methods that enhance performance, affordability, and (re) usability across healthcare, diagnostics, and industrial and environmental applications. Biosensors operating in complex environments often encounter issues such as biofouling, nonspecific adsorption, contamination-related interferences, stability limitations, and sample variability. Together, these issues compromise the sensor’s sensitivity, specificity, and real-time performance. Topics include, but are not limited to: unconventional biorecognition mechanisms that go beyond antibodies and enzymes, including advances in the use of aptamers, nanobodies, peptides, and molecularly imprinted polymers, among other biological and bioinspired elements, with a focus on design, selection, and evaluation. These strategies can be further improved through nanomaterialdriven signal enhancement. Sessions will explore the use of cost-effective and sustainable materials, such as paper-based cellulose-derived and other composites, to develop low-cost, printable, and disposable biosensing platforms. Additional discussions will focus on real-time, multiplexed biosensing for the simultaneous detection of analytes, and on the design of ingestible and minimally invasive sensors for physiological monitoring, including emerging ingestible formats. The integration of artificial intelligence and machine learning in bioelectroanalysis will be discussed in relation to data processing, feature extraction, and decision support. Biohybrid interfaces combine biological components with synthetic materials to improve biocompatibility and enable stable, long-term signal recordings for sophisticated biosensing applications. This session provides a platform for sharing methods, datasets, and practical insights to support the translation of biosensor technologies into reliable, context-aware measurements of complex environments.
