Nanotechnology is one of the fastest and tremendously developing branches of science and technology in the last years [1, 2]. Nanotechnology focuses on the design and synthesis of nano-sized materials, which have tremendous applications in various fields of science such as biological and synthetic chemistry [3]. At nanometer range the phenomenon is that the atomsatoms' few tenths have a diameter of nanometers, and typically a few molecules in nanometer size [4]. Nanomaterials are smaller observed particles that showed very promising chemical, biological, and physical properties depending on the nanomaterials' size, morphology, and shape [5-7]. However, these materials show a wide range of applications in various areas such as biomaterials, nanomedicines, environment, imaging, nan-electronicsnano-electronics, industry, and agriculture, and the use of nanotechnology for diagnosis, treatment of various diseases, novel drug formulation, cell tracking, tissue repair, and drug delivery in the healthcare sector [8-10].
The magnetic nanoparticles (MNPs) are the materials that impact nanomedicine, analytical chemistry, and bio-sensing [11]. However, there were many types of different nanoparticles and MNPs which include in the class of new technologies which provide interfaces among physics, biology, and chemistry. MNPs were used in clinical practices as contrast-enhancing agents in magnetic resonance imaging. Besides, various methods are created for these complexes in hydrophobic comprising interactions and electrostatic interactions [12].
These materials currently gain much interest to fabricate and design such as nano-bio composites, including MNPs and molecules of nucleic acid, which have a wide range of applications such as nanoelectronics, biomedical diagnosis, therapy, magnetic separation, and MRI [13, 14].
