  • Publication number: 20210080333
    Abstract: The present invention relates to a composition for temperature sensors including graphene oxide, DNAzyme and PNA, a temperature sensing method and a kit using the same. In the present invention, when the DNAzyme/PNA duplex is dissociated at a certain temperature, graphene oxide adsorbs PNA with excellent selectivity and irreversibility, enabling recall of temperature, to permit delayed color development in the time of need. Also, the target temperature can be easily and quickly detected with the naked eye through the color change of the colorimetric reagent, and the thermosensor is technically convenient and easy to apply, so it can be used in various biological applications. Moreover, it can be used as a barcode (on/off) system using a combination of PNA probes with various lengths, and thus can be broadly applied to sensing a diverse range of temperatures.
