For numerous key applications in medicine, chemistry, and physics the mechanical manipulation of nano-elements is of fundamental importance. In this regard, the demonstration of an optical force with spatial resolution of few hundreds of nanometres led to the 2018 Nobel prize for the invention of optical tweezers. However, the need for alternative tools capable of overcoming current limitations is only growing. For instance, optical tweezers require the targeted nano-elements to have certain shapes while being constituted by a set of semi-transparent materials to be fully effective. In addition to this, the small magnitude of the force limits the use of this technology to sub-micron scale particles. The proposed project aims at enriching the toolbox for mechanical handling of nano/micro-objects with a new optical force that so far exists only in the theoretical realm. This mechanical force will be triggered by ultra-fast optical pulses and has the potential to address previously listed limitations.

对于医学，化学和物理学中的许多关键应用，纳米元素的机械操纵至关重要。在这方面，具有数百种纳米空间分辨率的光学作用的演示导致了2018年诺贝尔光学镊子发明的奖项。但是，需要克服当前限制的替代工具的需求只是在增长。例如，光镊需要靶向的纳米元素具有某些形状，同时由一组半透明材料组成，以完全有效。除此之外，力的小幅度限制了该技术对亚微米尺度颗粒的使用。拟议的项目旨在丰富工具箱，以机械处理纳米/微观对象的机械处理，并以迄今仅存在于理论领域中的新光学力量。这种机械力将由超快速的光脉冲触发，并有可能解决先前列出的局限性。
