Makes sense: Copper metal organic framework (MOF) nanoelectrodes are prepared by depositing copper benzene tricarboxylate MOF (HKUST-1) into open carbon nanopipettes and used for sensing hydrogen peroxide.

In this study, the up-conversion luminescence for aqueous suspensions of carbon dots with polyfunctional and carboxylated surfaces synthesized by a hydrothermal method was investigated. The obtained quadratic dependence intensity on power exciting radiation indicates that these is caused two-photon absorption. optimal wavelength determined studied samples. dependences signal pH value suspension...
