我们研究了在激光照射下金纳米颗粒（GNP）从软基底到另一基底的快速释放和转移机制。用连续波激光器加热软衬底上的GNP导致衬底的快速热膨胀，这可用于选择性地释放GNP并将其放置到另一表面上。利用这种方法成功地制备了面内和面外纳米结构。这种快速释放和放置过程可用于在环境条件下添加非制造金属纳米结构，这为负担得起的纳米制造铺平了道路，并实现了纳米光子学，超灵敏传感和非线性等离子体的各种应用。
We investigated a mechanism for quick release and transfer of gold nanoparticles (GNPs) from a soft substrate to another substrate under laser illumination. The heating of GNPs on a soft substrate with a continuous-wave laser causes a rapid thermal expansion of the substrate, which can be used to selectively release and place GNPs onto another surface. In-plane and out-of-plane nanostructures are successfully fabricated using this method. This rapid release-and-place process can be used for additive nonmanufacturing of metallic nanostructures under ambient conditions, which paves a way for affordable nanomanufacturing and enables a wide variety of applications in nanophotonics, ultrasensitive sensing, and nonlinear plasmonics.
