以聚己内酯和纳米粒子作为基本构筑基元,利用自下而上式的自组装方法,可以构造出基于高分子单晶的具有多种功能的纳米马达.通过此种构造方法可以精确控制马达的形状、结构以及尺寸,而且通过引入不同的功能分子或纳米粒子可以实现多种功能.这种复合纳米马达由铂催化过氧化氢产生氧气提供动力,可以在溶液中自主运动,并由磁场控制其运动方向.药物运输、可控缓释、检测等多种功能也可以一步集成到马达当中.此种构筑方法不依赖于昂贵的仪器,可以实现马达的大批量生产,具有较好的应用前景.
Using polycaprolactone and nano-particles as the basic building blocks, a nano-motor with multiple functions based on single crystal can be constructed by a bottom-up self-assembly method, through which precise control can be achieved Motor shape, structure and size, but also through the introduction of different functional molecules or nanoparticles can achieve a variety of functions.The composite nano-motor from platinum-catalyzed hydrogen peroxide to produce oxygen, can be autonomous movement in solution by the magnetic field Control the direction of its movement.Motor transport, controlled release, testing and other functions can also be integrated into the motor which step.This method of construction does not rely on expensive equipment, can achieve high-volume motor production, has a good application prospect.
