Claim 0:
1. A silver nanocluster (Ag9-NCs) fluorescent nanotube, characterized in that, the Ag9-NCs fluorescent nanotube is obtained by a supramolecular self-assembly process of Ag9 under an induction of DD-5;
wherein the DD-5 is formed by a polymerization of five aspartic acids; the Ag9 is nine-nuclear Ag with Ag as core and 2-mercaptobenzoic acid (H2mba) as ligand; and
the supramolecular self-assembly process is to mix Ag9 aqueous solution with DD-5, vortex, and let it stand for 8 hours in 20° C. incubator to obtain the Ag9-NCs fluorescent nanotube;
wherein the Ag9 aqueous solution is produced by dispersing AgNO3 and H2mba in water with ultrasonic treatment, and adding NH3·H2O; and the Ag9-NCs fluorescent nanotube is sensitivity to L-Arg only, which is specifically used for detecting L-Arg.
