High-fidelity tissue super-resolution imaging achieved with confocal2 spinning-disk image scanning microscopy - Light: Science & Applications C²SD-ISM integrates an SD and a DMD to form a dual confocal configuration, enabling deep-tissue super-resolution imaging with DPA-PR reconstruction.

C²SD-ISM combines physical defocus rejection (spinning disk) with adaptive algorithm (DPA-PR), breaking depth limits in tissue super-resolution (↑180 μm), enhances fidelity (92% linear correlation), and supports high-throughput imaging. doi.org/10.1038/s413... Github: github.com/Chauncey-Leu....

Ultra-stable, ultra bright, congratulations!

Congratulations to Suyi Zhong, Wei Ren, Ziyi Yang, and Hongyu Wang!

If you have a dual channel, it can certainly be implemented on either one, or both.😁

Oh no, it does not need any hardware modification. It is like any Fiji plugin - it removes the fluorescence background through algorithm.😁

Congratulations Stephan!🎉🎉🎉

I am very glad to see that our PolarSIM helps the leading scientists to observe richer dynamics and get more discovery! Congratulations to Zhixing team for this brand new palette of fluorescent dyes named after BeiDa! www.nature.com/articles/s41... @pku1898.bsky.social @zhixingchen2.bsky.social

Thank you! 😁😁😁

Nice work! We integrated this dark-sectioning method into our FlexSIM pipeline (github.com/esoubies/Fle...) as an additional option for handling out-of-focus signal. It works remarkably well!

In particular, it handles out-of-focus regions more effectively than traditional OTF attenuation.

Our groundbreaking Dark Sectioning technique is now published in Nature Methods! 🎉 It supercharges existing imaging systems:
🔬 Widefield → Confocal
🔬 Single-photon → Multiphoton
🔬 2D-SIM → 3D-SIM
Now integrated in Airy PolarSIM and #FlexSIM!
