Graphitic carbon nitride (g-C3N4) has gained significant attention due to its unique physicochemical properties as a metal-free, two-dimensional, carbon-based polymeric fluorescent substance composed of tris-triazine-based patterns with slight hydrogen content and carbon-to-nitrogen ratio 3:4. It forms layered structures like graphite demonstrates exciting unusual properties, making g-C3N4 widely used in nanoelectronic devices, spin electronics, energy storage, thermal conductivity materials, many others. The biomedical industry greatly benefited from excellent optical, electrical, characteristics, such abundance on Earth, affordability, vast surface area, fast synthesis. Notably, the heptazine phase displays stable electronic bands. Another quality this semiconductor material is fluorescence property, which also helpful preparing biosensors. Based g-C3N4, electrochemical biosensors have provided better biocompatibility, higher sensitivity, low detection limits, nontoxicity, selectivity, versatility functionalization for delicate identification target analytes. This review covers latest studies using efflorescent graphitic fabricate various biomarkers. Carbon nitrides been reported possess electroactivity massive surface-to-volume ratio, hydrogen-bonding functionality, thus allowing electrochemical-based, highly sensitive, selective platforms an entire array Considering preceding information, addresses fundamentals background numerous synthesis pathways. Furthermore, importance sensing diverse biomarkers emphasized article. discusses current status challenges future perspectives nitride-based sensors, open paths toward their practical application aspects clinical diagnostics.

Abstract Dopamine can be used as a biomarker for diseases such Alzheimer’s, bipolar disorder, schizophrenia, mania, to mention few, well addiction tobacco. Thus, its measurement is of biomedical importance. We present an easy-to-construct, one-step, electrochemical sensor dopamine based on drop coating commercial graphene/poly (3,4-ethylenedioxythiophene):polystyrene sulphonate (Gr-PEDOT:PSS) hybrid ink dispersion bare glassy carbon electrode surface. The conductive polymer’s structural properties and composition were explored using XRD, Raman, FTIR spectroscopy electron microscopy. nanocomposite exhibited uniform size distribution functional groups aromatic, thiol, olefinic bonds improved the surface chemistry between electrolyte/analyte electrode. Characterization through impedance voltammetry demonstrated that Gr-PEDOT:PSS significantly enhances transfer kinetics at therefore improve electrooxidation dopamine. achieved detection limit 0.19 µM within linear concentration range 3.13–400 It also high selectivity against potential interfering agents like ascorbic acid, caffeine, urea, with recovery percentages ranging from 105 109% in human serum samples.
