Potassium-doped graphene enhanced electrochemiluminescence of SiO2@CdS nanocomposites for sensitive detection of TATA-binding protein

Based on the amplified signal from SiO2@CdS nanocomposites integrated with K-doped graphene, a new electrochemiluminescence biosensor was developed for the successful detection of transcription factor TATA-binding protein (TBP).
