Speech Title: Synthesis of Graphene and Two-Dimensional Nanomaterial Composites for Electrochemical Biosensors and Energy Storage Applications

Abstract: The existing carbon materials can be classified into activated carbon (0-dimensional), carbon nanotubes (CNT) (1-dimensional), graphene (2-dimensional) and carbon foams (3-dimensional). Among these, graphene is well known to be the top candidate; However, preparation of graphene from graphite is an intricate procedure that can lead to an explosion during the oxidation of graphite. The synthesis of a novel neodymium sesquioxide nanoparticles (Nd2O5 NPs) decorated graphene oxide (GO) nanocomposite under ultrasonic probe has been reported. After then, SEM, TEM, XRD, EDX and electrochemical impedance spectroscopy characterized was analyzed using Nd2O5 NPs@GO nanomaterial. Furthermore, the nanomaterial modified GCE (glassy carbon electrode) shows excellent electrochemical sensing performance towards anti-cancer drug. Raloxifene is one of the important anti-cancer drug. Moreover, the fabricated electrochemical sensor has showed a wide linear range for raloxifene between 0.03-472.5 µM and nanomolar detection limit (18.43 nM). In addition, the Nd2O5 NPs@GO modified sensor has been applied to the determination of raloxifene in human blood and urine samples. Recently, the layered molybdenum diselenide with crystal structure has been pointed out as an efficient electrocatalyst for various electrochemical applications due to its interesting properties. Especially, the defect engineering makes the new concepts and designs to further enhance the electrocatalytic activity of layered structures. Encouraged by these studies, we have prepared the transition metals (M = Mn, Ni, Co and Fe) doped MoSe2 and applied as the electrode materials for bio/electrochemical sensors, biofuel cells, and supercapacitors applications. (i) Thus, we demonstrated the synthesis of Mn doped MoSe2 and reported the resultant defective sites. The Mn doping not only helps for enzyme immobilization and also enhances the electronic conductivity of layered material. The proposed Mb immobilized MnMoSe2 (Mb@MnMoSe2) exhibited an ultra-low detection limit and higher sensitivity of H2O2. In real sample analysis, the Mb@MnMoSe2 showed a feasible recovery range for H2O2 detection in human serum, urine and water samples. On the other hand, an in-vivo study by using the living cells showed the feasible current response.
