Photoelectrochemical immunosensor for methylated RNA detection based on g-C3N4/CdS quantum dots heterojunction and Phos-tag-biotin.

N6-methyladenosine (m6A) is an enigmatic and abundant internal modification in eukaryotic messenger RNA (mRNA), which could affect various aspects of RNA metabolism and mRNA translation. Herein, a novel photoelectrochemical (PEC) immunosensor was constructed for m6A detection based on the inhibition of Cu2+ to the photoactivity of g-C3N4/CdS quantum dots (g… CONTINUE READING
