Room-temperature phosphorescence logic gates developed from nucleic acid functionalized carbon dots and graphene oxide

Room-temperature phosphorescence (RTP) logic gates were developed using capture ssDNA (cDNA) modified carbon dots and graphene oxide (GO). The experimental results suggested the feasibility of these developed RTP-based “OR”, “INHIBIT” and “OR-INHIBIT” logic gate operations, using Hg2+, target ssDNA (tDNA) and doxorubicin (DOX) as inputs.
