The invention discloses a host-guest chemical mediation size-controllable luminous gold nanoparticle assembly as well as a preparation method and application of the host-guest chemical mediation size-controllable luminous gold nanoparticle assembly. The preparation method comprises the following steps: carrying out stirring reaction on a cyclodextrin derivative and a hydrophobic sulfydryl ligand in a solvent, and carrying out host-guest chemical recognition on host molecules and guest molecules to form a cyclodextrin inclusion compound solution; and adding the cyclodextrin inclusion compound solution into the chloroauric acid solution, uniformly stirring, finally adding a reducing agent, stirring for reaction, and purifying after the reaction is finished to obtain a gold nanoparticle assembly aqueous solution. The molar ratio of chloroauric acid to the cyclodextrin inclusion compound is changed, the gold nano assembly with the controllable size is obtained, the optical property of the gold nano assembly and t
