在这里，我们展示了子10 nm的空间分辨率采样的体积类似于360个分子与强场增强在样品尖端结通过实施贵金属基板（Au，Ag，Pt）在光诱导力显微镜（PiFM）。该技术显示了PiFM的多功能性和鲁棒性，并有望应用于超敏性和超空间分辨率的界面研究。
Here we demonstrate sub-10 nm spatial resolution sampling of a volume of similar to 360 molecules with a strong field enhancement at the sample-tip junction by implementing noble metal substrates (Au, Ag, Pt) in photoinduced force microscopy (PiFM). This technique shows the versatility and robustness of PiFM and is promising for application in interfacial studies with hypersensitivity and super spatial resolution.
