In this study, the sensitive and selective detection of bisphenol A (BPA) was achieved using a screen-printed carbon electrode (NFO/SPCE) modified with hydrothermally synthesized NiFe2O4 nanoparticles.
areas of neural networks, the GFET array sophisticated electronic circuits, and signal amplification procedures must be improved. The creation of 3D, extremely flexible, scalable GFET microarrays that can enable ultraflexibility and subcellular feature size could pave the way for significant progress in this field.
Sulfonamides are a broad assortment of drugs utilized in treating bacterial diseases in veterinary and human existence as anti-infection agents. The escalating usage of such medications requires explicit recognition. This work describes the electrochemical detection of sulfamethazine (SMZ) (a subgroup of sulfonamides) using strontium niobium combined with reduced graphene oxide (SN/rGO) as composite material. The structural and topological criteria illustrate the surface immaculateness and elemental presence of the crystalline material SN/rGO with XRD and FE-SEM analysis. Additional examinations of chemical states and the functional group were identified with XPS and FT-IR measurements. The feasibility of the sensor was inspected in the record of electrochemical studies. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) studies have demonstrated the effective implementation of the fabricated sensor with facilitating higher electroactive sites and enhanced conductance with SN/rGO. The amalgamation of SN and rGO has substantial influence with a lower limit of detection 6 nM with linearity from 0.009 μM to 128 μM. The limit of quantification was about 0.0224 μM. The specific detection acquired over anti-interference studies and real-world actualize over milk, honey, and human blood serum tests mirror SN/rGO modified platform’s viable capability. The construction of SN/rGO is envisioned as a promising dais for improved SMZ sensing in real samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
