Abstract
Breast cancer (BC) continues to be the most frequently diagnosed malignancy and the primary cause of cancer-related deaths among women globally. The traditional treatment modalities, such as chemotherapy, surgery, and radiotherapy, are often associated with significant toxicity to healthy tissues and systemic side effects, highlighting the pressing need for safer and more targeted therapeutic strategies. Recently, microneedle innovation has become an evident alternative for delivering anti-neoplastic agents, offering minimally invasive, transdermal administration that can bypass hepatic metabolism and reduce systemic toxicity. Microneedle (MNs) arrays hold potential not only for drug delivery but also for vaccination, diagnostic sampling, and targeted therapy in BC management. However, despite these promising attributes, there exists a notable gap in the scientific literature specifically addressing the application of microneedles in breast cancer therapy, with relatively few comprehensive studies in this domain. This review aims to bridge that gap by summarizing recent advancements in MN-based strategies for breast cancer treatment. It highlights the ability of MNs to enable simultaneous drug loading, controlled release, and improved patient compliance through non-invasive administration. Furthermore, the review discusses MN properties, mechanisms of action, therapeutic benefits, relevant clinical trials, patents, and future challenges, thereby providing a valuable resource for researchers and promoting the translation of MN technology into clinical practice for breast cancer management.
期刊介绍：
Biomedical Microdevices: BioMEMS and Biomedical Nanotechnology is an interdisciplinary periodical devoted to all aspects of research in the medical diagnostic and therapeutic applications of Micro-Electro-Mechanical Systems (BioMEMS) and nanotechnology for medicine and biology.
General subjects of interest include the design, characterization, testing, modeling and clinical validation of microfabricated systems, and their integration on-chip and in larger functional units. The specific interests of the Journal include systems for neural stimulation and recording, bioseparation technologies such as nanofilters and electrophoretic equipment, miniaturized analytic and DNA identification systems, biosensors, and micro/nanotechnologies for cell and tissue research, tissue engineering, cell transplantation, and the controlled release of drugs and biological molecules.
Contributions reporting on fundamental and applied investigations of the material science, biochemistry, and physics of biomedical microdevices and nanotechnology are encouraged. A non-exhaustive list of fields of interest includes: nanoparticle synthesis, characterization, and validation of therapeutic or imaging efficacy in animal models; biocompatibility; biochemical modification of microfabricated devices, with reference to non-specific protein adsorption, and the active immobilization and patterning of proteins on micro/nanofabricated surfaces; the dynamics of fluids in micro-and-nano-fabricated channels; the electromechanical and structural response of micro/nanofabricated systems; the interactions of microdevices with cells and tissues, including biocompatibility and biodegradation studies; variations in the characteristics of the systems as a function of the micro/nanofabrication parameters.
