摘要:

现有的光学显微镜通过收集从物体发射的光子来形成图像。在这里,我们报告的实验实现显微镜,而不需要直接与样品的光通信。为了实现这一点,我们扫描了一个单一的金纳米粒子作为纳米天线在近场的样品,并研究了其固有的辐射特性的修改,通过监测其等离子体光谱。

英文摘要:

The existing optical microscopes form an image by collecting photons emitted from an object. Here we report on the experimental realization of microscopy without the need for direct optical communication with the sample. To achieve this, we have scanned a single gold nanoparticle acting as a nano-antenna in the near field of a sample and have studied the modification of its intrinsic radiative properties by monitoring its plasmon spectrum.
