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 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...

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...
