Abstract
Nickel oxide (NiO) nanoparticles were synthesized using the co-precipitation method. The structural, morphological, optical and magnetic properties of NiO nanoparticles were investigated by X-ray Powder Diffraction (XRD), Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FTIR), UV-vis Spectroscopy and Vibrating Sample Magnetometer (VSM). The influence of sonication time on the physical characteristics of NiO nanoparticles was illustrated. The interactions of NiO nanoparticles with both glucose and lactose have been0 studied using UV-vis Absorption Spectroscopy and Fluorescence Spectroscopy. XRD pattern reveals that NiO nanoparticles exhibit a face-centered-cubic lattice structure with a crystallite size of 22.77 nm. The magnetic hysteresis demonstrates the ferromagnetic behavior of NiO nanoparticles at room temperature. The energy band gap increases, from 2.8 eV to 3.1 eV, with increasing sonication time from 5 to 20 minutes. It is found that the interaction of lactose-NiO nanoparticles is stronger than that of glucose-NiO ones. The obtained results can be investigated in future biomedical applications, especially in non-enzymatic biosensors.

Summary
Nickel oxide (NiO) nanoparticle besides of being a supreme transition metal oxide, it is one of the remarkable ptype semiconductors. 2017) worked on Amperometric biosensor based on two enzymes: glucose oxidase and β -galactosidase stuck on graphite electrode for the detection of both saccharides. Li et al (Li et al, 2016) worked on non-enzymatic glucose sensors depending on reduced graphene oxide supported binary catalyst of NiO/CuO nanocomposites prepared on the glassy electrode. Lorestani, Mahmoudian, & Alias, 2015) prepared a non-enzymatic glucose sensor based on copper oxide/ polypyrrole nanofiber/ reduced graphene oxide nanocomposite. He et al (He et al, 2018) proposed non-enzymatic glucose sensors based on cubic NiO hollow porous architecture electrode. This work is devoted towards the investigation of NiO nanoparticles’ characteristics and their compatibility for further investigation in biomedical applications as well as the influence of sonication time on physical characteristics of NiO nanoparticles and NiO-glucose –lactose interactions
