Nanotechnology has been the topic of extensive research and a great deal of interest among researchers. The manufacturing and utilization of nanoparticles (NPs) has expanded dramatically as a result of the rapid development of nanotechnology. Gold nanoparticles (AuNPs) are one of the most important nanoparticles, and they have been widely used for medical and non-medical applications as ideal material because of their unique distinct features: inert, biocompatible, and especially due to low toxicity.  

 Aimed for the development of a cost effective and efficient method. The proposed method has been involved in the photochemical preparation of gold nanoparticles and gold nanoparticles on graphene oxide nanostructures.The preparation of Gold nanoparticles can be done inwardly or outside by microbes, but outside the cell handling is facile in terms of insulation. Modified nanocellulose is a preferred technique for gold nanoparticle extraction. AuNPs have shown outstanding applications for diagnostic and therapeutic uses, including biosensor applications, tumor-targeting capability (Anticancer Activity) for cancer therapy, and precise drug delivery of nano-vehicles to diseased tissues.

G are emerging as promising nano materials to create nano scale therapeutic delivery systems. The aim of the study was to synthesis of highly mono disperse and stable gold nanoparticles functionalized with polyethyleneimine and polyethylene glycol , multipara metric investigation of their neuronal toxicological effects and evaluation of the cellular/suborgan biodistribution. Gold nanoparticles were synthesized and their surfaces were electrostatically modified by PEI and PEG. Dorsal root ganglion sensory neurones were isolated from BALB/c mice. Cell viability, apoptosis and ROS production were evaluated in vitro.

Drug penetration through the skin is significant for both transdermal and dermal delivery. One mechanism that has attracted attention over the last two decades is the transport pathway of nanoparticles via hair follicle, through the epidermis, directly to the pilosebaceous unit and blood vessels. Studies demonstrate that particle size is an important factor for drug penetration. However, in order to gain more information for the purpose of improving this mode of drug delivery, a thorough understanding of the optimal physical particle properties is needed. In this study, we fabricated fluorescently labeled gold nanoparticles  with a tight control over the size and shape. The membrane protein has immunogenic antigenic properties and coating of bacterial outer membrane protein on the surfaces of synthetic gold nanoparticles not only preserved the complex biological characteristics of bacteria but also provided greater immune responses as compared to outer membrane protein alone. So, it was concluded that the coating of bacterial outer membrane proteins on the surface of synthetic gold nanoparticles have synergistic effects to induce the immune responses and promising potential to develop the effective antibacterial vaccine against salmonellosis in poultry birds.

Metallic nanoparticles, especially gold nanoparticles, are used in the therapy of various diseases. Recently, many chemotherapeutic supplements or drugs have been formulated with gold nanoparticles. One option for synthesizing gold nanoparticles is to use herbs. Many previous studies have shown that medicinal herbs increase the antioxidant and cytotoxicity properties of gold nanoparticles against tumor cell lines. In this study, gold nanoparticles were prepared and synthesized in an aqueous medium using Cannabis sativa L leaf extract as stabilizing and reducing agents. In addition, we evaluated the anti-leukemia effects of gold nanoparticles against acute T-cell leukemia and lymphoblastic leukemia cell lines.
