“…They are widely used in industries, scientific research, and clinical diagnostics. Specifically, they increase the rate of reaction by lowering the activation energy required to convert [12], where the enzyme plays the role of counter ions, knowing that the ideal pH for the salivary amylase enzyme is (6.6-6.8) pH at a temperature of 37 o C substrates into the products. The catalysis by an enzyme is influenced by the nature of the medium, the substrate, the enzyme concentration, the temperature, the pH, and the presence of activators and inhibitors.…”

 Copper nanoparticles were produced using an electrochemical method with alphaamylase from camel saliva.  The size and shape of CuNPs were improved after adding alpha-amylase, resulting in stable 44nm particles.  The used process is eco-friendly, rapid, and non-toxic, utilizing CuSO 4 and varying enzyme concentrations.  Enhanced CuNPs dispersion and stability were achieved through coordination bonds with the enzyme.This study aims to explain the effect of adding the bioactive substance (alpha enzyme) to the electrolyte solution using electrochemical deposition. Through which copper nanoparticles are manufactured, the originality of the research lies in the presence of this addition as a new method in manufacturing nanoparticles in an electrochemical manner, as the alpha-amylase enzyme is extracted from camel saliva, and the product has been diagnosed using (EDX) and scanning electron microscope (FE-SEM) techniques. , Dynamic Light Scattering (DLS) technology, and Zeta potential. The proposed method is an easy, inexpensive, and environmentally friendly method where the alpha enzyme was used as a feedstock at concentrations of (0.25, 0.50, 0.57, and 1) g added to a solution containing the ideal sample obtained through the electrochemical precipitation process before adding the enzyme, as the solution before The addition process contains concentrated sulfuric acid (H 2 SO 4 ) at concentrations of (20, 30, 40, 50 and 60) g/ml. The regular shape and stable distribution can be observed after the addition compared to the shape of the particles before the addition in terms of shape and size. The process was carried out under constant conditions, including the current. Direct, voltage and temperature, and after the addition process, sulfuric acid was dispensed with, while the process conditions with the addition were at a temperature of 37 degrees Celsius and an incubation period that lasted a full hour before the electrodeposition process was carried out in accordance with the enzyme activity conditions, where a nanosized copper powder of a granular size was obtained. Approximately 44 nanometers. It is worth noting that the nanoparticle size was modulated using the experimental conditions, e.g., pH, reducing step, enzyme amount, or incubation time. This controlled synthesis allows the preparation of CuNP bionanoparticles at Cu 3.13 powder at a concentration of 80 g CuSO 4 + 0.50 α-amylase.
