首次提出了基于激光烧蚀技术，利用具有自旋的扭曲光在金属表面上制作金属针。所得的针显示出在目标表面上方至少10 μ m的高度和小于0.3 μ m的尖端直径。我们还展示了二维5 × 6微针阵列的制造。针的形状均匀，平均长度和尖端直径分别约为10和0.5 μ m。(C)2010年美国光学学会
Microneedle fabrication on a metal surface based on laser ablation using twisted light with spin was demonstrated, for the first time. The resulting needle showed a height of at least 10 mu m above the target surface and a tip diameter of less than 0.3 mu m. We also demonstrated the fabrication of a two-dimensional 5 x 6 microneedle array. The needles were uniformly well shaped with an average length and tip diameter of about 10 and 0.5 mu m, respectively. (C) 2010 Optical Society of America
