Glutamate (Glu) is a principal neurotransmitter owing to its significant function in physiological and pathological processes. Deviations Glu levels have been associated with the onset of various neurological disorders, implicating it as potential biomarker for conditions like epilepsy, stroke, Alzheimer’s disease, amyotrophic lateral sclerosis. Accurate detection essential prevention, diagnosis, treatment such diseases. Herein, highly sensitive non-enzymatic sensor introduced detect Glu. The electrochemical performance was studied by modifying glassy carbon electrode using cobalt-based metal-organic framework/graphene oxide composite (CoMG/GCE). Differential pulse voltammetry exhibited linear response from 20.0 1.00 × 10 3 μM at an alkali solution limit 3.10 μM. DPV utilized determine human blood serum samples standard addition method. This showed lowest interference popular species, indicating ability healthcare applications.

Technological advancements have spurred an emerging demand for flexible energy storage devices with high-power density and significant cycle stability. Here, environmentally-friendly approach has been developed to synthesize coral reef-bioinspired ultrathin NiCo layered double hydroxides (CRBI-LDH) composites on carbon felt (CF) substrates. The thin layer nanostructure, which consists of mesoporous LDH nanosheet arrays vertically grown onto the surface fibers, mimics natural architecture reefs create a highly efficient asymmetric supercapacitor. CF/CRBI-NiCo-LDH electrode exhibited remarkable specific capacitance 1661.6 F g−1 at current 1 A g−1, it still retained 1617.6 even when was increased 10 g−1. Moreover, revealed excellent cycling stability (96.7% retention after 3000 cycles). An 57.2 Wh kg−1 also observed power 820 W kg−1, supercapacitor employed CRBI-NiCo-LDH nanocomposite as cathode activated paste anode. This combination high performance, low cost, ease fabrication makes this promising development devices.
