The biosynthesis of nickel nanoparticles has gained significant interest due to their distinctive properties and eco-friendly preparation methods. Nevertheless, optimizing the nanoparticles' can be time-consuming challenging. Therefore, this study presents a microtechnology-based optimized process for producing using bacterial growth (Bacillus species). Nickel is precursor that by Bacillus species growth. Growth duration, pH, concentration were optimized. A gradient various pH ranges was obtained via hierarchical 2-inlet 6-outlet microfluidic network. network distinguished its capacity automated, precise generation sustained maintenance gradients precursors throughout experimental duration. An optimum observed at 6.5 7.1×10^{− 3} mol/L. time factor also investigated conditions factors above. Complete consumption optimally achieved after 13 days incubation within 20-day period. UV-Vis spectrophotometry, X-ray diffraction, electron dispersive spectrometry, scanning microscopy used characterize biosynthesized nanoparticles. Powder diffraction measured crystal size as 27.8 nm cubic phase 29.9 triangular shape.
