- Description
- NiFe?O? nanoparticles and L-argininefunctionalized NiFe?O? (NiFe?O4LA) were synthesized, characterized, and evaluated for antimicrobial performance and in vivo biocompatibility in a zebrafish embryo model. The XRD and HRTEM studies confirmed the formation of single-phase cubic spinel NiFe?O? with average crystallite size ? 2030nm. Surface modification with LA preserved the spinel structure while reducing crystallinity and hydrodynamic size 128.7nm. FTIR and XPS verified successful surface functionalization. UV vis measurements showed band-gap narrowing after La conjugation (Eg ? 3.23 ? 3.15eV). NiFe?O?LA exhibited enhanced antimicrobial activity compared with bare NiFe?O? against MRSA and C. albicans an effect attributed to enhanced surface interaction and ROS-mediated oxidative damage. The MIC values of C. albicans is found to 1200g/mL while in the case MRSA is about 900g/mL. The ROS assays with histidine modulation supported a role for redox activity in antimicrobial action. In vivo zebrafish embryo assays showed minimal developmental toxicity at tested exposures with better viability for the LA coated material.
