Bicomponent colorimetric probe based on carbon quantum dots and o-phenylenediamine for sensitive and selective Cu2+ sensing
{{output}}
A bicomponent colorimetric probe based on carbon quantum dots (CQDs) and o-phenylenediamine (OPD) was established for the detection of Cu2+. Theoretically, light-generated electrons from CQDs were trapped by the dissolved oxygen, resulting in the production of... ...
