Visual fluoride ion detection with a detection limit down to pmol L-1 is achieved through quenching/reactivating the fluorescence of N-doped graphene oxide.
We report a controlled migration of an iron nanoparticle (FeNP) coated polymer micromotor. The otherwise diffusive motion of the motor was meticulously directed through an in situ pH-gradient and an external magnetic field. The self-propulsion owing to the asymmetric catalytic decomposition of peroxide fuel was directed through a pH gradient imposed across… (More)
The influence of the protein content of the diet on glucose concentration (denoted by fluorescence intensity) and body weight was studied in the white rat. Rats of 30d of age received ad lib. a control diet containing 15% crude protein (Pl5), or a diet containing 23% crude protein (P23) or 35% crude protein (P35) and a fourth group of rats (P8) received the… (More)
