Abstract

In the present investigation, a novel eco-friendly synthesis of TeCe BNPs is fabricated from Cinnamomum camphora-mediated leaf extract. Biofabricated TeCe BNPs mediated by C. Camphora are characterized by various studies, such as UV–visible spectroscopy, XRD, SEM, HR-TEM, AFM, and XPS. The surface morphology of bioactive TeCe BNPs is visualized through SEM and AFM studies. The average particle size of TeCe BNPs is found to be 103 nm, with a zeta potential of 0.3, which confirms the stability and dispersive nature of BNPs. The decrease in absorption intensity with an increase in light irradiation reveals the primary degradation of keratin. FTIR studies confirm the formation of a disulfide band in the region of, 1115 cm⁻¹. Furthermore, an electrochemical biosensor based on C.Camphora mediated TeCe BNPs modified glassy carbon electrode was developed for the determination of keratin under optimal conditions. The biosensor exhibits a linear response in the potential range of 0.9–1.0 μm, with a limit of detection of 0.0562 μm and a detection limit of 4.8951E⁻⁴.
