MXenes, a recently developed class of 2D materials, have attracted considerable attention because of their graphene-like but highly tunable properties. It appears that the metallic properties of MXene titanium carbide are pronounced in near-infrared with well-defined localised surface plasmon resonance (LSPR). Here, we report on a curved photonic nanojet, known as the photonic hook, applied on a titanium carbide nanoparticle for the particle's optomechanical manipulation. We show that the optical forces generated and applied on titanium carbide nanoparticles of various shapes are based on the LSPR excitation in near-infrared. We compare the obtained results to traditional plasmonic gold nanoparticles which exhibit LSPR in visible. Considering the diversity of the MXene family, this study is a first step towards photonic devices that utilize optomechanical manipulation in near-infrared for biomedical research, optical trapping and others.

MXene Ti3C2 纳米颗粒在近红外区域形成光子钩

MXene 是最近开发的一类 2D 材料，由于其类似石墨烯但高度可调的特性而引起了广泛关注。 MXene 碳化钛的金属特性在近红外区域很明显，具有明确的局域表面等离子体共振 (LSPR)。在这里，我们报告了一种弯曲光子纳米喷射，称为光子钩，应用于碳化钛纳米颗粒上，用于颗粒的光机械操纵。我们表明，在各种形状的碳化钛纳米粒子上产生和施加的光学力是基于近红外的局域表面等离子体共振激发。我们将获得的结果与在可见光中表现出局域表面等离子体共振的传统等离子体金纳米颗粒进行了比较。考虑到 MXene 系列的多样性，这项研究是迈向利用近红外光机械操作进行生物医学研究、光学捕获等的光子器件的第一步。
