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、化学和物理学领域的众多关键应用来说，纳米元件的机械操作至关重要。在这方面，空间分辨率为数百纳米的光力的展示使光镊的发明获得了 2018 年诺贝尔奖。然而，对能够克服当前限制的替代工具的需求只会不断增长。例如，光镊需要目标纳米元件具有一定的形状，同时由一组半透明材料构成才能完全有效。除此之外，力的大小限制了该技术在亚微米级颗粒上的使用。该项目旨在利用迄今为止仅存在于理论领域的新光学力来丰富纳米/微米物体机械处理的工具箱。这种机械力将由超快光脉冲触发，并有可能解决前面列出的限制。
