Nanotechnology has opened up a new, previously unimaginable world in cancer diagnosis and therapy, leading to the emergence of cancer nanomedicine and nanoparticle-aided radiotherapy. Smart nanomaterials (nanoparticle drones) can now be constructed with capability to precisely target cancer cells and be remotely activated with radiation to emit micrometer-range missile-like electrons to destroy the tumor cells. These nanoparticle drones can also be programmed to deliver therapeutic payloads to tumor sites to achieve optimal therapeutic efficacy. In this article, we examine the state-of-the-art and potential of nanoparticle drones in targeting lung cancer. Inhalation (INH) (air) versus traditional intravenous ("sea") routes of navigating physiological barriers using such drones is assessed. Results and analysis suggest that INH route may offer more promise for targeting tumor cells with radiosensitizers and cannabinoids from the perspective of maximizing damage to lung tumors cells while minimizing any collateral damage or side effects.
纳米技术在癌症诊断和治疗领域开启了一个全新的、此前难以想象的世界,催生了癌症纳米医学和纳米粒子辅助放射治疗。如今,可以构建智能纳米材料(纳米粒子无人机),使其具备精确靶向癌细胞的能力,并通过辐射进行远程激活,以发射微米级导弹状电子来摧毁肿瘤细胞。这些纳米粒子无人机还可以进行编程,将治疗载荷输送到肿瘤部位,以实现最佳治疗效果。在本文中,我们研究了纳米粒子无人机在靶向肺癌方面的最新进展和潜力。评估了使用此类无人机通过吸入(INH)(空气)与传统静脉注射(“sea”)途径跨越生理屏障的情况。结果与分析表明,从最大化对肺肿瘤细胞的损伤同时最小化任何附带损伤或副作用的角度来看,吸入途径在利用放射增敏剂和大麻素靶向肿瘤细胞方面可能更具前景。
