4DescriptionAbstract In this work the particle size control method of copper nanoparticles synthesized using ascorbic acid as a bioreductant and glucose as a biostabilizing agent of sulphate of copper was investigated. The experiments were respectively carried out in a semibatch type reactor. Biosynthesis of metal nanoparticles using green reagents is an important area of research in nanobiotechnology which is an emerging eco-friendly science of well-defined sizes, shapes and controlled monodispersity. The characterization of synthesized NP?s was carried out by analytical tools like UV-Vis Spectroscopy, SEM and PSD to ascertain the size and polydispersity of NPs. The UV-Vis absorption spectrum shows its Surface Plasmon Resonance (SPR) leading to a strong band centered at 310 nm which can be assigned to a ligand-to-metal change transfer (LMCT) transition and other at 453 nm due to Cu NP?s stabilized by CuO which is in tandem with the reported data. XRD was also used to unravel the degree of crystallinity and lattice pattern in the biosynthesis of Cu metal Nanoparticles. It shows that Cu metal nanoparticles are crystalline but polydispersed and have oblongated face centred cubic (FCC) type of lattice pattern and the average particle size of the order 51 nm. A typical SEM image of the Cu nanoparticles showed the spherical but a bit oblongated morphology of particles with 50±2 nm diameter in size. Overall the particles were observed to be polydispersed but uniformly distributed. These results are expected to be of great interest as basic data for the preparation of size-controlled copper nanoparticles by using biosynthetic route
