Biological Smart Materials: Materials for Cancer Treatment

The field of biomedical materials has witnessed significant advancements in recent years, leading to the development of novel smart materials capable of interacting intelligently with the biological environment. This book chapter comprehensively explores the synthesis, applications, and safety considerations of nanomaterials in the context of cancer treatment. The chapter begins with an introduction to nanotechnology and its significance in biomedical research and cancer therapeutics. Next, the chapter explores the synthesis of nanomaterials, covering both top-down and bottom-up approaches. The top-down approach involves the fabrication of nanoparticles (NPs) from more extensive materials through techniques such as milling and lithography. In contrast, the bottom-up approach focuses on assembling nanoscale building blocks to form NPs using chemical synthesis and self-assembly methods. It highlights the importance of material selection, processing techniques, and integrating functional components, such as NPs, nanofibers, and hydrogels, to enhance their performance and efficacy. Furthermore, the chapter discusses bioconjugation strategies for biomedical applications, emphasizing their role in improving NP functionality and targeting abilities for cancer treatment. Various techniques, including surface modification and functionalization, are discussed to enhance the biocompatibility and specificity of NPs in targeting cancer cells. The chapter further delves into specific types of NPs used in cancer treatment. Plasmonic NPs, known for their unique optical properties, are examined for their applications in cancer therapy. Their use in photothermal therapy (PTT) is discussed, highlighting their potential in targeted cancer cell destruction. Inorganic-based NPs, specifically those employed in drug delivery systems and PTT, are investigated for their effectiveness in cancer treatment. Their controlled drug release mechanisms and targeted therapy capabilities are explored, showcasing their potential in combating cancer cells. Upconverting NPs, which can convert low-energy photons into high-energy emissions, are discussed in the context of cancer treatment. Their applications in PTT are explored, highlighting their potential for precise cancer cell targeting and destruction. Inspired by nature’s mechanisms, biomimetic-based materials for cancer treatment are examined. These materials mimic biological systems to enhance PTT, offering promising avenues for targeted cancer therapy.
