Silver nanowire-base fluorescent nanometer thermometer and preparation method thereof

The present invention discloses a silver nanowire-base fluorescent nanometer thermometer. According to the thermometer, a silver nanowire is adopted as a base; the surface of the silver nanowire is provided with a one-dimensional nanometer thermometer provided with a specific DNA fragment with fluorescent molecules, and an auxiliary chain T; the sequence of the specific DNA fragment is ATCTAATCATTATTGTTTTTTTTTTTTTTTACTATTATGTTTAGATTTTTTTTTTT of which the 3' end is modified with -(CH2)3-SH; and the fluorescent molecules is 5'TEXAS red; and the sequence of the auxiliary chain T is TTTTTTTTTT of which the 3' end is modified with -(CH2)3-SH. The present invention further discloses a preparation method of the above-mentioned fluorescent nanometer thermometer. According to the silver nanowire-base fluorescent nanometer thermometer and the preparation method thereof of the invention, the silver nanowire is adopted as the base, the fluorescent molecules are assembled on the surface of the silver nanowire through the
