Amplified electrochemiluminescence of quantum dots by electrochemically reduced graphene oxide for nanobiosensing of acetylcholine

Potassium-doped graphene enhanced electrochemiluminescence of SiO(2)@CdS nanocomposites for sensitive detection of TATA-binding protein

Based on the amplified signal from SiO(2)@CdS nanocomposites integrated with K-doped graphene, a new electrochemiluminescence biosensor was developed for the successful detection of transcription factor TATA-binding protein (TBP).

Facile in situ fabrication of graphene-upconversion hybrid materials with amplified electrogenerated chemiluminescence

A simple and general synthetic approach for one-step creation of graphene-upconversion nanocomposite by an in situ hydrothermal method has been developed. Using graphene oxide (GO) as a precursor reagent, the reduction of GO and the deposition of NaYF(4)/Yb,Er on graphene occur simultaneously. The electrogenerated chemiluminescent intensity of NaYF(4)/Yb,Er is significantly amplified by graphene due to its wonderful conductivity, extraordinary electron transport properties and large specific surface area.
