Comprehensive Characterization and Antibacterial Evaluation of Synthesized Magnetite Nanoparticles for Enhanced Biosensor Applications: A Multi-Instrumental Study Using FESEM, FTIR, And XRD Analyses

Abstract

In recent years, the development of advanced nanomaterials has gained significant attention due to their unique physicochemical properties and potential applications in various fields, including biotechnology and medicine. Magnetite nanoparticles (MNPs) have emerged as a promising candidate for biosensor applications owing to their magnetic properties and tunable surface functionalities. This study focuses on the comprehensive characterization of prepared magnetite nanoparticles and explores their potential antibacterial activity for biosensor development. The characterization involves the utilization of Field Emission Scanning Electron Microscopy (FESEM), Fourier-Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction (XRD) instrumental techniques to assess the size, smoothness, distribution, and crystal structure of the MNPs.
