Achieving low-power single-wavelength-pair nanoscopy with NIR-II continuous-wave laser for multi-chromatic probes

The authors introduce stimulated-emission induced excitation depletion (STExD) nanoscopy using a single pair of low-power, near-infrared, continue-wave lasers. Emission of multichromatic probes is inhibited by cascade amplified depletion in lanthanide upconversion systems induced by manipulating their common sensitizer.

Migrating photon avalanche in different emitters at the nanoscale enables 46th-order optical nonlinearity

A general mechanism, migrating photon avalanche, can generate large optical nonlinearity from various lanthanides emitters at the nanoscale.

Sequential pH-driven dimerization and stabilization of the N-terminal domain enables rapid spider silk formation

The molecular mechanism by which rapid spider silk assembly occurs in the glands of spiders is challenging to investigate. Here, the authors perform site-directed mutagenesis of the N-terminal domain and propose a three-step mechanism that allows controlled aggregation of spidroins.

Factor H binding proteins protect division septa on encapsulated Streptococcus pneumoniae against complement C3b deposition and amplification

Streptococcus pneumoniae evades the action of the complement system by expressing an immuno-protective polysaccharide capsule as well as Factor H-binding proteins. Here, Pathak et al. show that these two defence mechanisms are functionally and spatially coordinated on the bacterial cell surface.
