中文简介:
核壳纳米颗粒可用于生物医学应用,例如作为生物医学成像对比剂,用于热疗和药物递送,以及用于生物技术应用,例如分离和纯化。通过使用纳米级无机磁芯,如超顺磁性氧化铁纳米晶来控制与磁场的相互作用,可以实现独特的功能。使用具有受控形态和拓扑结构的密集接枝聚合物壳与蛋白质的相互作用可以在生物流体中进行调节,我们表明这最终会影响细胞相互作用和摄取。然而,为了使先进的材料在生物环境中发挥功能,例如特异性结合、聚集和药物释放,必须仔细设计接枝刺激响应聚合物壳或结构化两亲性和聚合物组件的集成。
课程简介: Core-shell nanoparticles can be used in biomedical applications, e.g., as biomedical imaging contrast agents, for hyperthermia and in drug delivery, as well as for biotechnological applications such as separation and purification. Unique functions can be achieved by using nanoscale inorganic cores, such as superparamagnetic iron oxide nanocrystals for controlling interactions with magnetic fields. Using densely grafted polymer shells with controlled morphology and topology interactions with proteins can be tuned in biological fluids and we show this ultimately affects cell interaction and uptake. However, to enable advanced materials functions in a biological environment, e.g. specific binding, aggregation and drug release, integration of grafted stimuli-responsive polymer shells or into structured amphiphile and polymer assemblies must be carefully designed.
