In recent years, the biomedical field has witnessed significant advancements at the intersection of technology and biology. Metallic, polymeric, and carbonaceous materials have emerged as crucial components in developing and enhancing cutting-edge technologies. The properties of these materials, such as particle size, stability, and surface chemistry, are determined by their synthesis methods, which, in turn, enable specific applications. These materials are primarily synthesized through top-down and bottom-up techniques, each characterized by distinct preparation conditions, precursor materials, and catalytic processes. However, conventional synthesis methods often require substantial energy consumption, hazardous solvents, and non-renewable precursors, leading to environmental concerns and long-term costs. This review aims to provide an overview of the primary approaches and recent efforts to optimize the production and preparation processes of nanomaterials for biomedical applications. It addresses the advantages and limitations of green synthesis methods compared to traditional chemical and physical methods, offering an objective overview of green synthesis. In addition, it provides insights into the pre-clinical and clinical statuses of various nanomaterials. These efforts aim to mitigate the environmental impact of biomedical material synthesis by adopting eco-friendly strategies, such as minimizing energy consumption, utilizing environmentally friendly precursors, and embracing environmentally benign catalytic methodologies, while still leveraging traditional techniques.
