Biosensors capable of onsite and continuous detection environmental food pollutants biomarkers are highly desired, but only a few sensing platforms meet the “2-SAR” requirements (sensitivity, specificity, affordability, automation, rapidity, reusability). A fiber optic evanescent wave (FOEW) sensor is an attractive type portable device that has advantages high sensitivity, low cost, good reusability, long-term stability. By utilizing functional nucleic acids (FNAs) such as aptamers, DNAzymes, rational designed acid probes specific recognition ligands, FOEW been demonstrated to be general platform for various targets ranging from small molecules heavy metal ions proteins, acids, pathogens. In this review, we cover progress fluorescent FNA-based biosensor since its first report in 1995. We focus on chemical modification optical mechanisms five above-mentioned types targets. The challenges prospects isolation high-quality reagent-free detection, stability under application conditions, throughput also included review highlight future trends development biosensors detection.

The increasing demand for rapid, cost-effective, and reliable diagnostic tools in personalized point-of-care medicine is driving scientists to enhance existing technology platforms develop new methods detecting measuring clinically significant biomarkers. Humanity confronted with growing risks from emerging recurring infectious diseases, including the influenza virus, dengue virus (DENV), human immunodeficiency (HIV), Ebola tuberculosis, cholera, and, most notably, SARS coronavirus-2 (SARS-CoV-2; COVID-19), among others. Timely diagnosis of infections effective disease control have always been paramount importance. Plasmonic-based biosensing holds potential address threat posed by diseases enabling prompt monitoring. In recent years, numerous plasmonic risen challenge offering on-site strategies complement traditional like polymerase chain reaction (PCR) enzyme-linked immunosorbent assays (ELISA). Disease detection can be accomplished through utilization diverse phenomena, such as propagating surface plasmon resonance (SPR), localized SPR (LSPR), surface-enhanced Raman scattering (SERS), fluorescence (SEF), infrared absorption spectroscopy, sensors. This review focuses on employing sensors, highlighting their pivotal role swift remarkable sensitivity. It underscores necessity continued research expand scope capabilities sensors field diagnostics.
