In recent years, atmospheric pressure plasma jet (APPJ) has become a simple and rapid method to deposit thin films on substrates. On the other hand, plasma polymerized acrylic acid has received great attention for applications in biomedical and biosensors. In this study, we fabricated a metal-based catalytic biosensor by APPJ for the detection of hydrogen peroxide, using acrylic as a monomer to grow thin film on ITO substrate and N,N’-methylene-bis-acrylamide as a cross-linking agent. The fabricated electrodes were characterized via scanning electron microscopy (SEM), contact angles, Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), and cyclic voltammetry (CV). From analysis data, the formation of metal oxides through plasma jet was confirmed. The fabricated biosensors are suitable for detecting H2O2 in real samples. |
