Mohammad Hassan Ramezan zadeh: Iron oxide reinforced carbon nanotubes as promising nanofillers for biosensing applications of polymer films

Mohammad Hassan Ramezan zadeh, Majid Seifi Department of Physics, Faculty of Science, University of Guilan, Rasht 41335, Iran Carbon nanotubes (CNTs) have been widely investigated owing to their exceptionally structural and physicochemical properties which make them great candidates for numerous applications, such as, hydrogen storage, capacitors, sensors, biomarkers etc. [1, 2]. We have studied the influence of single walled carbon nanotubes coated with iron oxide nanoparticles (SWCNT-iron oxide nanocomposites) on the electrochemical properties of 2- dimensional polymer matrices and applied them as the frontier materials in electrochemical biosensors. In the present study, first, we synthesized SWCNT-iron oxide nanocomposites by following  a same methodology reported previously [3], and then used them as nanofillers in gelatin films to make them applicable materials for electrochemical sensing in different branches, such as food industry, high-tech packaging, new medicine, biomedical devices, agricultural industry etc.  This novel work could increase the different real-life applications of electrochemical biosensors for modern mankind as well as the over-increasing elderly population health care issues. 1.

I am developing new apparatuses about increasing polymers' structural, physical and biological properties by using carbon nanotubes and nanoparticles. Polymers such as chitosan, PVA, etc. The applications are supposed to be in various regions like biomedical, medical, life, food and environmental sciences.
