A rapid and sensitive fluorescence sensing system for melamine based on charge transfer quenching of the fluorescence of graphene quantum dots (GQDs) in the presence of Hg2+ is proposed. The ...

From declogging drains to hanging cookbooks, see all the brilliant ways you never thought to use your clothes hangers. You ...

In this work, a robust and reliable electrochemical sensor was developed for sensitive detection of non-electroactive melamine (MEL) using a modified glassy carbon electrode with ascorbic acid (AA) as ...
