Method for conducting chiral induction to non-chiral cyanine dye aggregate using human serum protein

The invention relates to a method to take chiral induction to non-chiral cyanine dye aggregate by using human albumin that includes the following steps: dissolving non-chiral cyanine dye and human albumin aggregate into phosphoric acid to form 80um and 50um solution, mixing the solution to make the mol ratio to 0.5-5:1; diluting the phosphoric acid solution to 5um, taking non-light reaction for 9-15 hours to gain cyanine dye aggregate, taking analysis by ultraviolet visible absorption spectrum and circle dichromatism spectral, the aggregate has chirality and chirality reversing. The invention could adjust the optical rotation of dye aggregate solution.
