Ultrasensitive detection, biological sensor, chemical sensor, even applications in environmental science, the potential for 3D plasmonic nanostructures in plasmon enhanced fluorescence (PEF) is fairly impressive. In this week’s image Zhenglong Zhang et al control the distance between the molecules and metal surface by altering the size of the porous alumina array. You can read their full results here.
