Bio-inspired, programmable biomacromolecules based nanostructures driven cancer therapy

Abstract

Cancer remains a significant global health challenge, driving the development of advanced platforms for highly targeted and efficient drug delivery. Early-stage nanocarriers, such as synthetic polymeric and inorganic materials, face limitations in biocompatibility and biodegradability. In contrast, bioinspired nanocarriers derived from natural biomacromolecules mimic biological processes and present a promising alternative due to their biocompatibility, biodegradability and non-toxicity. The effectiveness of these drug delivery systems is influenced by factors such as size, shape, surface properties, morphology, functionalization, and preparation methods. Various biomacromolecule-inspired nanocarriers such as protein-based, lipid-based, carbohydrate-based and nucleic acid-based are now at the forefront of research. This review highlights the properties, advantages and limitations of different bioinspired materials. We also explore cutting-edge approaches for cancer therapy using these nanocarriers with recent in-vitro, in-vivo and patent evidence. Finally, we address the challenges and potential solutions associated with bioinspired nanocarriers, proposing future directions. Overall, this review explores nature-inspired drug delivery systems that have paved the way for advancements in cancer therapy.
