The detection of lead ions in water is therefore essential not only for balancing economic and environmental priorities, improving public services, and ensuring agricultural safety, but also for preventing lead poisoning, promoting health equity, and safeguarding international trade in the context of global health. Conventional detection methods are often limited by expensive instrumentation and complex procedures, whereas surface-enhanced Raman scattering (SERS) has emerged as a promising alternative due to its high sensitivity and operational simplicity. In this study, we developed an ultrasensitive SERS-based method for the Pb2+ detection using L-cysteine-functionalized bismuth nanoparticles as probes. L-cysteine binds Pb2+ through its −COOH and −NH2 groups, inducing nanoparticle aggregations and generating Raman hotspots that enhance the signal of 4-aminothiophenol (4-ATP). Additionally, an electrodeposited bismuth substrate further amplifies the SERS response.

The NiO/CuO composite exhibits higher concentration of oxygen vacancies and interface lattice distortion compared to their individual counterparts. The NiO/CuO composite exhibits exceptional photoelectrochemical MOR activity and stability. The enhanced performance is attributed to the synergistic effect of the NiO/CuO heterojunction and the high concentration of oxygen vacancies, which together improve light absorption, increase the electrochemically active surface area, provide more active sites, and accelerate charge transfer kinetics.

Its abundant amino and hydroxyl groups provide versatile sites for derivatization, enabling tailored solubility, mechanical performance, and functional responsiveness. These attributes make chitosan well suited for wearable and implantable emotion-sensing systems; however, challenges remain, including environmental stability, signal drift under large deformation, and maintaining long-term skin comfort.

Here we map these coupled effects using ferrocene (Fc) monolayers grafted onto hydrogen-terminated p- and n-type Si(100), Si(110), and Si(111). Successful functionalization was confirmed by X-ray photoelectron spectroscopy and cyclic voltammetry. The Fc surface coverage (Γ) is strongly facet dependent and, in particular, doping reverses the facet selectivity: p-type follows (100) > (110) > (111), whereas n-type follows (111) > (110) > (100). In contrast, the Fc/Fc+ mid-point potential shows a consistent orientation hierarchy for both dopings ((100) > (110) > (111)) with an additional ∼20–40 mV positive shift on n-type relative to p-type, indicating robust redox energetics with doping-controlled offsets. Peak widths exceed the ideal surface-confined limit and, together with impedance responses, point to non-ideal behavior dominated by interfacial electrostatics rather than ohmic artifacts.
