Near‐Infrared‐Driven Metal–Organic Frameworks‐Based Nanorobots for Controlled Photothermal‐Chemical Therapy Synergistic Induction of Cancer Cell Death

Advanced Robotics Research, EarlyView.
To achieve efficient cancer cell death, a bowl‐shaped PDA@UiO‐66@DOX nanorobot drug‐delivery nanoplatform was developed. Near‐infrared irradiation not only drives the nanorobot to exhibit self‐thermophoretic motion and elevates temperature but also triggers Doxorubicin (DOX) release via hyperthermia, enhancing cancer cells uptake of DOX and thereby ...

Polydopamine-Functionalized Graphene Oxide: A Versatile Nanocarrier for Chemotherapy and Photothermal Therapy [PDF]

, 2015
光热治疗是一种新型的肿瘤治疗技术，与传统的治疗手段相比，其具有独特的优点，如侵入性低、恢复时间短及并发症发生率小，而将光热治疗与传统的化学药物治疗结合在一个体系里，使热和化疗药物同时作用于肿瘤部位，能够更有效的杀死癌细胞。 石墨烯作为一种二维碳纳米材料，具有超高的比面积和强的近红外光吸收能力，在药物输送与光热治疗方面有着潜在的应用价值。然而，目前的研究中，石墨烯主要是通过π-π堆叠和疏水性相互作用装载疏水性药物，无法实现对那些与之无相互作用的亲水性药物的装载 ...

Antibacterial Silver Nanoparticle Containing Polydopamine Hydrogels That Enhance Re-Epithelization

Gels
A polydopamine polyelectrolyte hydrogel was developed by ionic crosslinking dextran sulfate with a copolymer of polyethyleneimine and polydopamine. Gelation was promoted by the slow hydrolysis of glucono-δ-lactone.
