Abstract Fluorescence‐based biosensors have widely been used in the life‐sciences and biomedical applications due to their low limit of detection a diverse selection fluorophores that enable simultaneous measurements multiple biomarkers. Recent research effort has made implement fluorescent into exploding field point‐of‐care testing (POCT), which uses cost‐effective strategies for rapid affordable diagnostic testing. However, fluorescence‐based assays often suffer from feeble signal at analyte concentrations, requires sophisticated, costly, bulky instrumentation maintain high sensitivity. Metal‐ metal oxide‐based nanostructures offer simple solution increase output generation enhancements close or oxide surface, shown improve excitation rate, quantum yield, photostability, radiation pattern fluorophores. This article provides an overview existing employ various fluorescence enhancement via demonstrated potential use as POCT. Biosensors using such planar substrates, freestanding nanoparticles, metal–dielectric–metal nanocavities are discussed with emphasis placed on technologies promise towards POCT without need centralized laboratories.

While nanoscale quantum emitters are effective tags for measuring biomolecular interactions, their utilities applications that demand single-unit observations limited by the requirements large numerical aperture (NA) objectives, fluorescence intermittency, and poor photon collection efficiency resulted from omnidirectional emission. Here, we report a nearly 3000-fold signal enhancement achieved through multiplicative effects of enhanced excitation, highly directional extraction, improvement, blinking suppression photonic crystal (PC) surface. The approach achieves single dot (QD) sensitivity with high signal-to-noise ratio, even when using low-NA lens an inexpensive optical setup. capability PC improves QDs on-time 15% to 85% ameliorating intermittency. We developed assay cancer-associated miRNA biomarkers single-molecule resolution, single-base mutation selectivity, 10-attomolar detection limit. Additionally, observed differential surface motion trajectories attachment stringency is altered changing base in cancer-specific sequence.

Abstract Digital‐resolution biosensing based on resonant reflection from photonic crystals (PC) has demonstrated significant potential for detection of proteomic and genomic biomarkers in serology, infectious disease diagnostics, cancer diagnostics. An important intrinsic characteristic metamaterial surfaces is that enhanced electromagnetic fields are not uniformly distributed, resulting spatially variable light‐matter interactions with nanoparticle tags signal the presence biomarker molecules. In this work, spatial uniformity resonantly enhanced, surface‐confined a 1D PC compared 2D fourfold symmetry. When illuminated unpolarized light, simultaneously excited transverse electric magnetic modes present equally strong but complementary distribution, leading to >100% increased average near‐field intensity accompanied >50% compressed standard deviation PC. Utilizing Photonic Resonator Absorption Microscopy (PRAM) experimentally measure absorption ≈80 nm gold nanoparticles distributed upon surface, improvement observed when using Overall, AuNP contrast, uniformity, point spread function by PRAM performed surface.
