P Ganesh Consultancy and Analytical Servies, Hebbal Industrial Area, Mysuru, India-570016, India Journal Article 2024 03 30 CeCuIn₂O₅ trimetallic oxide nanoparticles (CCI NPs) were synthesised in the current work and examined for antibacterial activity against Methicillin Resistant <em>Staphylococcus Aureus</em> (MRSA), photocatalytic degradation of malachite green (MG) and electrochemical sensing of sodium nitrite. The physicochemical characteristics of the CCI NPs were analyzed using XRD, SEM, EDX, UV-vis and DLS method which depicts the morphology, crystalline nature and particle size synthesised CCI NPs. With a linear range of 0.8-4.8mM, the glassy carbon electrode (GCE) modified CCI NPs demonstrated an outstanding electrochemical response for sodium nitrite (NaNO₂). In addition, the synthesized CCI NPs showed high photocatalytic activities for the degradation of MG dye in water. It indicates the CCI NPs material produces hydroxyl (^⋅OH) and superoxide (O₂⁻) radicals for MG degradation when exposed to UV light, also showed an efficiency of 89.6% towards the degradation of Malachite Green. Carried out the dose-dependent method to the standard antibiotic streptomycin at 10 g/disc (5, 7, 15, 20, 25 & 30) with a zone of inhibition (ZOI) of 25.27- 45.27±0.09 in mm CCI NPs showed excellent antibacterial activity against MRSA in a dose-dependent method. As a consequence, it was found that CCI NPs are an effective multifunctional material that can be scaled up for the quantification of NaNO₂, photocatalytic dye degradation of malachite green, and antibacterial activity against MRSA. https://www.abechem.com/article_716157_0891c767eb8fea78290d3bd823f7aa6e.pdf
