Cancer-associated fibroblasts (CAFs) play a crucial role in the tumor microenvironment by promoting growth, immune evasion, and metastasis. Recently, drug delivery systems targeting CAFs have emerged as promising long-term effective approach to cancer treatment. Advances nanotechnology, particular, led development of nanomedicine designed specifically target CAFs, offering new possibilities for precise personalized therapies. This article reviews recent progress using nanocarriers that CAFs. Additionally, we explore potential combining multiple therapies, such chemotherapy immunotherapy, with enhance efficacy overcome resistance. Although many preclinical studies show promise, clinical application still faces considerable challenges, especially terms penetration large-scale production. Therefore, this review aims provide fresh perspective on CAF-targeted highlight future research directions applications.
