Hyperthermia has shown tremendous therapeutic efficiency in the treatment of cancer due to its controllability, minimal invasiveness and limited side effects compared to the conventional treatment techniques like surgery, radiotherapy and chemotherapy. To improve the precision of hyperthermia specifically to a tumor location, near infra-red (NIR) light activatable inorganic metal nanoparticles have served as effective photothermal therapy materials, but toxicity and non-biodegradability have limited their clinical applications. Conjugated polymer nanoparticles have overcome these limitations and are emerging as superior photothermal materials owing to their excellent light harvesting nature, biocompatibility and tunable absorption properties. In this review we focus on the development of organic conjugated polymers (polyaniline, polypyrrole, polydopamine etc.) and their nanoparticles, which have broad NIR absorption. Such materials elicit photothermal effects upon NIR stimulation and may also serve as carriers for delivery of therapeutic and contrast agents for combined therapy. Subsequently, the emergence of donor-acceptor based semiconducting polymer nanoparticles with strong absorbance that is tunable across the NIR have been shown to eradicate tumors by either hyperthermia alone or combined with other therapies. The design of multifunctional polymer nanoparticles that absorb near- or mid- infrared light for heat generation, as well as their diagnostic abilities for precise biomedical applications are highlighted.

用于热疗、成像和药物输送的共轭聚合物纳米系统。

与手术、放疗和化疗等常规治疗技术相比,热疗由于其可控性、微创性和有限的副作用,在癌症治疗中显示出巨大的治疗效率。为了提高热疗对肿瘤位置的精确度,近红外 (NIR) 光可激活无机金属纳米粒子已作为有效的光热治疗材料,但毒性和不可生物降解性限制了它们的临床应用。共轭聚合物纳米粒子克服了这些限制,并且由于其优异的光收集性质、生物相容性和可调吸收特性而成为优异的光热材料。在这篇综述中,我们重点关注有机共轭聚合物(聚苯胺、聚吡咯、聚多巴胺等)及其纳米粒子,具有广泛的近红外吸收。此类材料对 NIR 刺激产生光热效应,并且还可用作递送治疗剂和造影剂以用于联合治疗的载体。随后,基于供体-受体的半导体聚合物纳米粒子的出现,具有可在近红外波段可调的强吸光度,已被证明可以通过单独使用热疗或与其他疗法相结合来根除肿瘤。强调了吸收近红外或中红外光以产生热量的多功能聚合物纳米粒子的设计,以及它们在精确生物医学应用中的诊断能力。此类材料对 NIR 刺激产生光热效应,并且还可用作递送治疗剂和造影剂以用于联合治疗的载体。随后,基于供体-受体的半导体聚合物纳米粒子的出现,具有可在近红外波段可调的强吸光度,已被证明可以通过单独使用热疗或与其他疗法相结合来根除肿瘤。强调了吸收近红外或中红外光以产生热量的多功能聚合物纳米粒子的设计,以及它们在精确生物医学应用中的诊断能力。此类材料对 NIR 刺激产生光热效应,并且还可用作递送治疗剂和造影剂以用于联合治疗的载体。随后,基于供体-受体的半导体聚合物纳米粒子的出现,具有可在近红外波段可调的强吸光度,已被证明可以通过单独使用热疗或与其他疗法相结合来根除肿瘤。强调了吸收近红外或中红外光以产生热量的多功能聚合物纳米粒子的设计,以及它们在精确生物医学应用中的诊断能力。已经证明,基于供体-受体的半导体聚合物纳米颗粒的出现可以通过单独的热疗或与其他疗法相结合来根除肿瘤,该纳米颗粒具有在近红外波段可调的强吸光度。强调了吸收近红外或中红外光以产生热量的多功能聚合物纳米粒子的设计,以及它们在精确生物医学应用中的诊断能力。已经证明,基于供体-受体的半导体聚合物纳米颗粒的出现可以通过单独的热疗或与其他疗法相结合来根除肿瘤,该纳米颗粒具有在近红外波段可调的强吸光度。强调了吸收近红外或中红外光以产生热量的多功能聚合物纳米粒子的设计,以及它们在精确生物医学应用中的诊断能力。
