چکیده
Panchromatic Luminescent Silver Nanodots In article number 2201121, Junhua Yu and colleagues show that panchromatic luminescent silver nanodots can be generated by cluster transference in a single step, with excellent spectral purity chemical stability. This strategy utilized fields such as imaging several targets after turn-on step; it also used for fast efficiently visualizing printed micropatterns on the surface.

Generation of luminescent noble metal nanodots in cell matrices.
Cell matrices were used as rich libraries to screen proteins for the production of luminescent silver and gold nanodots. The study indicates that the proteins for silver and gold nanodot protection are quite different. The identification of such proteins in future may enrich the family of luminescent nanodots.
متن کاملHighly luminescent carbon nanodots by microwave-assisted pyrolysis.
Carbon nanodots (CDs) with a low cytotoxicity have been synthesized by one-step microwave-assisted pyrolysis of citric acid in the presence of various amine molecules. The primary amine molecules have been confirmed to serve dual roles as N-doping precursors and surface passivation agents, both of which considerably enhanced the fluorescence of the CDs.
متن کاملDNA-encapsulated silver nanodots as ratiometric luminescent probes for hypochlorite detection
UNLABELLED DNA-encapsulated silver nanodots are noteworthy candidates for bio-imaging probes, thanks to their excellent photophysical properties. The spectral shift of silver nanodot emitters from red to blue shows excellent correlations with the concentration of reactive oxygen species, which makes it possible to develop new types of probes for reactive oxygen species (ROS), such as hypochloro...
متن کاملMetamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).
By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.
متن کاملLuminescent Blinking from Silver Nanostructures.
Silver nanostructures deposited on glass showed luminescent blinking when excited at a high 442 nm irradiance. The irradiance required to photoactivate the silver, was dependent on the nature of the silver nanostructures. Silver fractal-like structures were found to be highly emissive, requiring only ≈30 W/cm(2) for photoactivation as compared to silver island films and spin-coated silver collo...
