Description
Summary:Super‐Linear Image Scanning Microscopy In article number 2400746, Yao Wang, Baolei Liu, Fan Wang, and co‐workers experimentally demonstrate a super‐linear image scanning microscopy (SL‐ISM) that enhances spatial resolutions beyond the diffraction limit in a straightforward manner, by harnessing the nonlinear emission of nanoprobes. A resolution of ≈120 nm, 1/8th of the excitation wavelength is achieved by only using a single low‐power, continuous‐wave, near‐infrared laser. This work suggests a simple and low‐cost method for super‐resolution imaging or sensing, multi‐photon imaging, and deep‐tissue imaging.
