光热电热钳的最新进展为低功率捕获和操纵纳米粒子开辟了新的途径,在胶体组装、纳米制造、生命科学和纳米医学中具有潜在的应用前景。然而,为了充分利用光热潜水镊子的广泛应用,提高它们在纳米颗粒操作中的通用性是关键。为此,我们将我们最新开发的光热渗透镊子移植到光纤平台上,称为光热渗透光纤镊子(OTFT)。我们已经展示了OTFT作为纳米颗粒浓缩器、作为单颗粒输送的纳米管以及作为纳米探针的应用。OTFT的简单设置和功能多样性将鼓励其在各种领域的使用,如添加剂制造、单纳米颗粒-细胞相互作用和生物传感。
Recent advances in opto-thermophoretic tweezers open new avenues for low-power trapping and manipulation of nanoparticles with potential applications in colloidal assembly, nanomanufacturing, life sciences, and nanomedicine. However, to fully exploit the opto-thermophoretic tweezers for widespread applications, the enhancement of their versatility in nanoparticle manipulations is pivotal. For this purpose, we translate our newly developed opto-thermophoretic tweezers onto an optical fiber platform known as opto-thermophoretic fiber tweezers (OTFT). We have demonstrated the applications of OTFT as a nanoparticle concentrator, as a nanopipette for single particle delivery, and as a nanoprobe. The simple setup and functional versatility of OTFT would encourage its use in various fields such as additive manufacturing, single nanoparticle-cell interactions, and biosensing.
