Summary: In this study, a fast and simple method using PVP-assisted silver mirror reaction was employed to synthesize SERS fiber probes with controlled morphology of silver nanoparticles on optical fiber facets. By optimizing reaction conditions, including various parameters such as PVP/AgNO3 ratio and type of reducing saccharide, the resulting fiber probes showed high sensitivity and reproducibility when detecting 4-aminothiophenol (4-ATP). Furthermore, the localized electromagnetic field of silver nanoparticles was simulated to explain the amplified SERS signal of the fiber probe, which demonstrated potential applications in flexible detection for early diagnosis and critical conditions in various environments.

Summary: In this study, Ag hybrid p-n junction of Ag3PO4/BiPO4 was synthesized through P123 assisted co-precipitation method with different molar ratios. The optimized molar ratio resulted in an intergrowth structure composed of spherical Ag3PO4 decorated with nano-cocoon BiPO4. The heterostructure exhibited enhanced photocatalytic activity, with 81.4% degradation of tetracycline hydrochloride in 30 minutes and a reaction rate 3.21 times faster than pure Ag3PO4. Furthermore, an optimized photocatalyst extended light absorption, reduced charge carrier recombination, and facilitated carrier transfer across the p-n junction. The participation of superoxide radical O-2(center dot-) species was found to dominate the photocatalytic reaction, and a plausible mechanism was proposed to explain the elevated activity. Textile effluents and the degradation of dyes (MB, RhB, CR, MO) were also analyzed.

Summary: Surface-enhanced Raman scattering spectroscopy (SERS) is a powerful vibrational spectroscopy technique that utilizes the inelastic scattering of photons by molecules. It has unique properties such as ultra-sensitivity, selectivity, non-destructivity, speed, and fingerprinting properties, making it widely used in sample analysis and plasmonic mechanistic studies. However, the high cost and low reproducibility of SERS signals limit its practical applications. The development of multifunctional, stable, and reusable nano-engineered SERS substrates provides a feasible solution to overcome these limitations.

Summary: A novel SERS probe was designed and fabricated for specific capture and fast detection of small molecule ligands binding to target protein. The probe was successfully synthesized by coating SiO2@Ag nanoclusters with 6-chlorohexanoic acid for immobilization of serotonin transporter (5-HTT). Through characterization and verification using TEM, XPS, and elemental mapping, the probe was applied to analyze Gardenia jasminoides extract and successfully identified crocin I as a compound binding to 5-HTT. The study demonstrates the potential of combining SERS with affinity-guided molecular capture in drug screening.

Summary: Investigation into the mechanism of oxygen vacancy-regulated photoelectrochemical sensors for highly sensitive and selective detection of biomolecules with electron-donating groups is an innovative research field. This study synthesized oxygen vacancy-regulated TiO2 nanotube arrays with high photoelectrochemical activity and applied them to detect tetracycline hydrochloride. The synergistic effect of oxygen vacancies and Ti3+ in the nanotube arrays led to increased generation of photogenerated carriers, while the adsorption of tetracycline hydrochloride consumed the oxygen vacancies and decreased the photocurrent response of the sensor. The sensor showed excellent linearity in the range of 0.1-1000 nM and high selectivity for tetracycline hydrochloride determination.
