Laser-Assisted Chemical Bath Synthesis (LACBS) was used to fabricate pure and magnesium-doped zinc oxide nanoparticles. Analysis of these nanoparticles' structural, morphological, optical, antimicrobial characteristics conducted. This analysis spanned across varying concentrations from 1% 3%. XRD confirmed the crystalline nature, revealing hexagonal wurtzite phase. SEM showcased their nanometric domain existence morphology, transforming nanorods nanotubes. Optical showed band gap energy decrease 3.27 2.85 eV correlating with magnesium doping concentration increase. absorption displayed a distinctive redshift for nanoparticles as increased Photocatalytic assessments highlighted superior degradation ability 3% Mg-doped nanoparticles, showing 98.04% rate against methylene orange dye under blue light exposure. Antimicrobial activity tests various pathogens that Mg ions' incorporation significantly enhanced performance, demonstrating effectiveness LACBS method.
