Summary: This paper provides a detailed theoretical analysis of the temperature rise near magnetite/gold and magnetite/silver core/shell nanospheres submerged in water, using the Lorenz theory and the electrostatic-thermal transfer analogy approach. Localized surface plasmon resonances are found to be the most efficient in photothermal effect. Gold and silver nanospheres allow a significant, almost uniform temperature rise at their vicinities, with spectrally localized stimulating light at 389 nm and 535 nm, respectively. Magnetite/gold and magnetite/silver core/shell nanospheres also exhibit an important photothermal effect, with the interesting ability to tune the frequency of stimulating light from ultraviolet to near infrared by adjusting the global diameter and relative thickness of the nanosphere's shell. The distribution of temperature rise over the plasmonic shell-water interface becomes non-uniform for a decreasing relative shell thickness.

Summary: Bio-Ag/ZnO NCs were synthesized using mangosteen peel extract as a reducing agent. The samples synthesized at different microwave temperatures showed significant differences in size and crystallinity, affecting their electrocatalytic behavior and sensing performance. The Z(90) sample exhibited the highest electrochemical performance due to improved particle size distribution and crystal microstructure. The proposed nanosensor showed high electrochemical sensitivity (0.303 μA μM-1 cm(-2)) and a low detection limit (LOD≈0.27 μM) for carbaryl pesticide detection. Overall, bio-Ag/ZnO NCs are promising for the development of a high-performance electrochemical-based nanosensor for rapid and eco-friendly detection of carbaryl pesticide residues in agricultural products.
