Developing an electrochemiluminescence (ECL) coreactant to minimize the biotoxicity and to maximize the enhancement factor is critical to single-cell ECL microscopy. Here, we reported a guanine-rich single-stranded DNA (G-ssDNA)-loaded high-index fac

The effects of photobleaching on electrochemiluminescence (ECL) was investigated for the first time. The plasma membrane of Chinese Hamster Ovary (CHO) cells was labeled with a [Ru(bpy)3 ]2+ derivative. Selected regions of the fixed cells were photob

Heterojunction photocatalysts are widely adopted for efficient water splitting, but ion migration can seriously threaten the stability of heterojunctions, as with the well-known low stability of CdS-Cu2-xS due to intrinsic Cu+ ion migration. Here, we
