Green synthesis techniques are being preferred as more simplistic and eco-friendly approaches for the synthesis of metal/metal oxide nanoparticles than the traditional physical and chemical routes. In recent years, nanoparticles of noble metals such as gold, silver, and palladium have drawn immense attention due to the wide range of their innovative applications in various fields of industry, particularly the biomedical and environmental fields. Thus, it is very important to evaluate their toxicity, to make sure of its biosafety. For instance, silver nanoparticles have attracted significant interest in medical applications, such as diagnosis, treatment, medical device coating, drug delivery, personal health-care products, and as excellent antibacterial agents. Which somehow would approve its biosafety. However, the design and fabrication of nanomaterials with well-controlled physicochemical features and morphological properties to be applied in the human body and environment, remain the focus of many researchers. Nevertheless, the mechanisms for safe utilization, application, and accumulation still need further studies. This chapter aims to discuss the biosafety and medical applications of different green synthesized nanoparticles to approve its recommendation to be applied for pollutant remediation and water treatment. Furthermore, this chapter addresses toxicity issues and the safety rules related to biomedical applications.
