Nanospeckle Illumination Microscopy (NanoSIM) utilizes plasmonic nanoisland structures to enable super-resolution surface imaging of live cells. By analyzing the intensity fluctuations of plasmonic nanospeckles, we achieved three-fold improved spatial resolution and the ability to identify multiple cellular structures. Experimental results demonstrate the potential of NanoSIM as an effective and versatile tool for investigating dynamic cellular processes within live cell membranes of HeLa cells, providing crucial insights into complex cellular interactions.
