1. one kind has the preparation method of the golden nanometer particle single thin film of chirality, it is characterised in that step is:

  • (1) synthesis of golden nanometer particle;

    adopt citric acid reduction method synthesis golden nanometer particle;

    (2) golden nanometer particle functional modification;

    by the golden nanometer particle of synthesis in step (1) and L D halfcystine coupling, formation Au-L Dcys complex body;

    (3) preparation of chiral gold nano particle single layer film;

    by the Au-L in step (2) Dcys complex body be placed in Glass Containers, form immobilon-p by adding normal hexane and ethanol at interface;

    chiral gold nano particle single layer film;

    (4) sign of chiral gold nano particle single layer film;

    the immobilon-p of step (3) gained is carried out transmission electron microscope and scanning electron microscope, ultraviolet, circular dichroism sign, obtains having the golden nanometer particle single thin film of chirality.
