Photoswitchable polymer nanoparticles (ps-PNPs) have been constructed by emulsion polymerization through embedding an iridium(III) complex, [Ir(bt)2(pic)](bt = phenylbenzothiazole, pic = picolinate), as a fluorophore and a diarylethene derivative (DTE) as a photochrome. The ps-PNPs show reversible luminescence modulation with DTE switching using UV light in aqueous solution and even in living cells...
Upconversion nanophosphors (UCNPs) have been widely used in bioscience and bioimaging, but the effect of UCNPs on plants and on animals after subsequent oral ingestion of the plants has not been studied previously. Herein, we investigate the effects of UCNPs on plant development using mung beans as a model. Incubation at a high UCNP concentration of 100 μg/mL led to growth inhibition, while a low...
