Nanoscience and nanotechnology are evolving with the new physical laws encountered as the structures and devices we make become smaller. Quantum-level effects manifest in new ways to manipulate electrical, magnetic, optical, mechanical – virtually all – properties of materials in surprising but exceedingly useful ways. Optical physics and quantum optics have embodied these trends to push resolving power well below the classical diffraction limit in areas of near-field, confocal, plasmatronic and multi-photon microscopy, prodding an Nobel Prize in Chemistry in 2014 for super-resolution optical microscopy. Such tools are opening the frontiers of nanoscience by enabling the formation, interrogation and manipulation of nanostructures down to the size of single molecules while laser projection lithography has come to define the nanotechnology forefront for high-volume manufacturing of microelectronic chips with transistor gate widths of 10 nm – just a few atoms thick (TSMC, 2017).

随着我们制造的结构和设备变得越来越小，纳米科学和纳米技术正在随着新的物理定律而发展。量子级效应以新的方式表现出来，以令人惊讶但非常有用的方式操纵材料的电，磁，光，机械-几乎所有-属性。光学物理学和量子光学已经体现了这些趋势，在近场，共聚焦，等离子体和多光子显微镜领域将分辨率推到远低于经典衍射极限的水平，并在2014年因超分辨率光学显微镜而获得诺贝尔化学奖。这些工具正在打开纳米科学的前沿，使纳米结构的形成，询问和操纵下降到单分子的大小，而激光投影光刻已经定义了大批量制造微电子芯片的纳米技术前沿，晶体管栅极宽度为10 nm -只有几个原子厚（台积电，2017）。
