The broader impact/commercial potential of this I-Corps project is the development of a novel device for simultaneous optical and oscillating magnetic field irradiation of a target. This device has potential applications in broad areas of basic, translational, and clinical research as well as biomedical and pharmaceutical industrial applications, which involve the unique nanoplatform characterization and efficacy assessment of next generation small molecule drugs and biologics toward the development of novel therapeutic approaches. The success of this project will enable advanced therapies to induce ultimate combined tumor cell destruction. This I-Corps project advances translation of a photo-magnetic hybrid field-generating device for simultaneous optical and oscillating magnetic field irradiation of a target to address the synergistic effects of photothermal, magnetothermal, and photodynamic activations. Using this device, a multimodal comprehensive strategy called “hybrid photo-magnetic stimulation” that has been unexplored previously is implemented with various materials and biological systems. This device permits simultaneous optical and (low/high frequency) AC magnetic field exposure, and thereby generates cumulative or synergetic effects depending on the target’s composition and characteristics. This novel technology permits the use of a less intense AC magnetic field in combination with optical stimulation during the irradiation process, thus removing the safety concerns associated with the AC magnetic field-assisted therapies. Using this device, it has been observed that smart nanostructure-based photo-magnetic hybrid irradiation is a viable approach to remotely guide tumor cell destruction, which may be adopted in clinical management to treat aggressive cancers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个I-Corps项目更广泛的影响/商业潜力是开发一种新的装置，用于同时对目标进行光学和振荡磁场照射。该装置在基础、转化和临床研究以及生物医学和制药工业应用的广泛领域具有潜在的应用，其中涉及下一代小分子药物和生物制剂的独特纳米平台表征和功效评估，以开发新型治疗方法。该项目的成功将使先进的治疗方法能够诱导最终的联合肿瘤细胞破坏。该I-Corps项目推进了光磁混合场产生设备的翻译，用于同时对目标进行光学和振荡磁场照射，以解决光热，磁热和光动力激活的协同效应。使用该设备，一种称为“混合光磁刺激”的多模式综合策略，以前未被探索过，可以用各种材料和生物系统实现。该设备允许同时暴露于光学和（低/高频）AC磁场，从而根据目标的组成和特性产生累积或协同效应。这种新技术允许在照射过程中使用强度较低的AC磁场与光学刺激相结合，从而消除了与AC磁场辅助治疗相关的安全性问题。使用该设备，已经观察到基于智能纳米结构的光磁混合辐射是远程引导肿瘤细胞破坏的可行方法，可以用于临床管理以治疗侵袭性癌症。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
