This study introduces an advanced photo-induced-photo-catalytic SERS (PI-PC SERS) technique, achieving exceptional ultrasensitivity while ensuring substrate reusability.
Cobalt doped magnetite nanoparticles (Co x Fe3-x O4 NPs) are investigated extensively because of their potential hyperthermia application. However, the complex interrelation among chemical compositions and particle size means correlation with magnetic heating properties is not trivial to predict. Here, we prepared Co NPs (0 ≤ 1) investigate effects cobalt content on properties. A detailed analysis structural features indicated similarity between crystallite sizes as well non-monotonic change...
In this work, photocatalytic performance is divulged in the ternary CuO-Ag-ZnO nanowire synthesized via a two-step approach. The decoration of Ag and CuO nanostructures onto surface ZnO nanowires was simply carried out by using plasma electrolytic oxidation method short time. structure, size, morphology, optical properties as-prepared samples were characterized X-ray diffraction, field-emission scanning electron microscopy, spectrophotometry measurements. diameters nanoparticles nanoflowers...
Plasmonic sensors have broad application potential in many fields and are promising to replace most bulky the future. There various method-based chemical reduction processes for silver nanoparticle production with flexible structural shapes due their simplicity rapidity fabrication. In this study, self-assembled nanoparticles (Ag NPs) a plasmon peak at 424 nm were successfully coated onto -NH2-functionalized glass optical fiber sensors. These coatings rapidly produced via two denaturation...
In this study, we developed a pioneering non-enzymatic electrochemical sensor utilizing flexible porous graphene electrode modified with ZnO nanoparticles (ZnO/fPGE sensor) to assess hypoxanthine (HXA) content in pork at post-mortem time. The ZnO/fPGE was synthesized via hydrothermal method and direct laser writing CO2 on polyimide film ambient conditions. Its characterization analyzed by Raman, Fourier-transform infrared spectroscopy, field-emission scanning microscopy, energy-dispersive...
In this study, we developed an advanced Fe 3 O 4 @C@Ag nanostructure-based SERS substrate, enabling ultra-sensitive, reliable, and practical detection of the low-Raman-cross-section biomolecule, urea.
Urea, methylene blue and Congo red were employed to investigate SERS performance of a ZIP-8/Ag heterostructure. Small dimensions allowed urea be adsorbed into ZIP-8 framework, leading enhancement in its signal while the others not.
Surface-enhanced Raman scattering (SERS) is an advantageous method for organic chemical and biological sensing. Benzoic acid, benzisothiazolinone, thiram are common model compounds used to study the interaction of toxic substances with metal surfaces using SERS spectroscopy. Metal-organic frameworks, their high porosity large surface area, have recently received a lot attention in sensing applications. Plasmonic porous structures promising substrates because broadband charge-transfer...
Optical characteristics of Gd 3 Ga 5 O 12 :Mn and prototype UV-driven LED coated with phosphor.
ZnO/Ag nanocomposites with different ZnO contents were prepared for Raman measurements of ofloxacin. Impressive SERS enhancement was achieved by the effects Ag and ZnO, individually, as well combining two components.
