    Nanotherapies combined with stimuli-triggered activated agents have become attractive ways to traditional chemotherapy. The Fe3O4 nanoparticles was employed as the core coated firstly with hydrogels of dually loaded both doxorubicin and hematoporphyrin monomethyl ether. Then, the folic acid was grafted onto the surface of the composites to construct a laser-sensitized magnetic nanoparticles (LMNs), followed by these LMNs being loaded into BC membrane. On the 14th day after treatment, tumor growth inhibition (TGI) was evaluated to 80.38% under the target system. When delivered transdermally under a magnetic field and laser, the synthesized BC/LMNs could offer solutions to challenge in breast cancer treatment, including the limited penetration depth, which could facilitate the bypassing of the stratum corneum barrier and enhance transdermal drug delivery.
    1. Introduction
    Breast cancer is a common life-threatening illness and a leading cause of death. The main treatments of the breast cancer currently in-clude surgery, chemotherapy, and radiotherapy [1–3]. But, these treatments have limited efficacy, side effects and toxicity. Therefore, alternative and effective therapeutic approaches for the treatment of
    In the research process of anticancer drug delivery for surface cancer treatment, the skin has emerged as an important alternative route, which would eliminate the need for conventional invasive ad-ministration procedures. In addition, localizing treatment could mini-mize undesirable systemic effects and could prevent cases of pessimal stimulation and toxicity. However, the stratum corneum of the skin
