#Upconverison nanoparticles are good because they don't "blink", unlike conventional dyes. But every rule has an exception - here's a new paper about blinking #UCNPs for super-res microscopy! #optics #photonics #chemsky

Spontaneous photoblinking in Yb3+/Ho3+-codoped upconversion nanoparticles enables super-resolution imaging of biological cells with a spatial resolution down to 30 nm at excitation power densities of ...
