Super‐Resolved Multiplexing Microscopy
The optical nonlinearity of lanthanide‐doped nanoparticles can be transported by a vortex excitation beam onto the imaging point spread function for differentiating single nanoparticles. In article number 2308844, Chaohao Chen, Faliang Cheng, Lan Fu, Xiaoxue Xu, Fan Wang, and co‐workers propose a novel and efficient dimension, optical nonlinearity, for super‐resolved...
Optical multiplexing for nanoscale object recognition is of great significance within the intricate domains of biology, medicine, anti‐counterfeiting, and microscopic imaging. Traditionally, the multiplexing dimensions of nanoscopy are limited to emission intensity, color, lifetime, and polarization. Here, a novel dimension, optical nonlinearity, is proposed for super‐resolved multiplexing microscopy...
