Transforming bone cancer treatment: a comprehensive review of green-synthesized metal nanoparticles

Abstract

Osteosarcoma (OS), chondrosarcoma (CHS), and Ewing sarcoma (EWS) are the main types of bone cancer (BC). OS is the most common BC in this group. It is most common in children and older people, especially in their long bones. Treatments for bone sarcomas and tumors have slowly improved, so researchers began looking into additional and alternative approaches to standard therapies. Therefore, the ability to precisely manipulate metallic nanoparticles (MNPs)' form, size, charge, and surface modification makes them very useful in treating bone cancer. However, due to the biocompatibility and possible toxicity of MNPs, MNP has limits for clinical use in treating BC. Therefore, the green synthesis of MNPs is achieved by bio-reducing metallic ions, which results in the creation of NPs, using living entities or their extracts. Green MNPs derived from natural sources provide a secure and environmentally responsible solution. Benefits of green MNPs include tailored medicine delivery and biocompatibility. Green MNPs reduce damage to healthy cells while improving the targeting of bone cancer cells. In this study, we reviewed how different MNPs synthesized using green methods can help treat various types of BC. This work reviewed the usual way of making MNPs for treating BC, the problems with this standard way of making MNPs, and the benefits and possible future uses of green synthetic MNPs for treating BC.
