The resolution of conventional surface-plasmon-resonance (SPR) imaging has been limited by the diffraction nature of light. A wide-field extended-resolution optical imaging technique, standing-wave SPR fluorescence (SW-SPRF) microscopy, has been developed. Based on evanescent SPR standing waves, SW-SPRF provides lateral resolution approaching 100 nm and offers the advantages of significant signal enhancement and background-noise reduction. SW-SPRF has the potential for sensitive biomolecular detection, nanoscale imaging, and lithographic applications.
传统表面等离子体共振（SPR）成像的分辨率一直受光的衍射特性限制。一种宽场扩展分辨率光学成像技术——驻波SPR荧光（SW-SPRF）显微镜已被开发出来。基于倏逝SPR驻波，SW-SPRF提供接近100纳米的横向分辨率，并具有显著增强信号和降低背景噪声的优点。SW-SPRF在灵敏的生物分子检测、纳米级成像和光刻应用方面具有潜力。
