Abstract:
Osteosarcoma (OS) is the most prevalent malignant primary bone tumor, predominantly affecting children and young adults between the ages of 11 and 20. OS presents huge challenges in treatment because of its aggressive nature and high metastatic potential. Chemotherapeutic drugs have attracted considerable interest for the treatment of OS, but they suffer from poor targeting, low bioavailability, severe side effects, and the multi-drug resistance acquired by the tumor. Therefore, it is imperative to develop novel therapeutic tactics that can improve OS outcomes while minimizing toxicity. Bioinspired nanoparticles, designed through exploiting or simulating the biological structures and processes, provide promising strategies for the treatment of OS. In this review, we elaborate on the biological properties and biomedical applications of state-of-the-art bioinspired nanoparticles, including cell membrane-based nanoparticles, exosome-based nanoparticles, protein template-based nanoparticles, and peptide template-based nanoparticles for the management of OS.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
