可控地处理最小材料的能力是纳米科学的基本技术。传统的光镊已被证明可用于操纵微尺度物体,但不能施加足够的力来操纵小于约100 nm的介电材料。最近,已经开发了几种近场光学捕获技术,其可以提供更高的捕获刚度,但是由于极高的电磁场和由此产生的局部温度升高的组合,它们在可逆地捕获和释放较小材料的能力方面往往受到限制。在这里,我们开发了一种新形式的光子晶体“纳米镊子”,可以捕获和释放威尔逊病蛋白质,量子点和22纳米聚合物颗粒,温度上升小于~0.3 K,低于不必要的流体机械效应将阻止捕获或损坏生物靶点的温度。
The ability to controllably handle the smallest materials is a fundamental enabling technology for nanoscience. Conventional optical tweezers have proven useful for manipulating microscale objects but cannot exert enough force to manipulate dielectric materials smaller than about 100 nm. Recently, several near-field optical trapping techniques have been developed that can provide higher trapping stiffness, but they tend to be limited in their ability to reversibly trap and release smaller materials due to a combination of the extremely high electromagnetic fields and the resulting local temperature rise. Here, we have developed a new form of photonic crystal “nanotweezer” that can trap and release on-command Wilson disease proteins, quantum dots, and 22-nm polymer particles with a temperature rise less than ~0.3 K, below the point where unwanted fluid mechanical effects will prevent trapping or damage biological targets.
