    Abstract: PURPOSE: A nanosensor containing glycol chitosan-coated gold nanoparticles, peptides, and fluorescent substances is provided to diagnose certain disease such as cancer. CONSTITUTION: A nanosensor for detecting protease contains glycol chitosan-coated gold nanoparticles, peptides, and fluorescent substances. The peptide has 9-15 amino acid containing a protease cleavage site. One end and the other end of the peptide are conjugated with fluorescent substances and glycol chitosan of gold nanoparticles, respectively. The protease includes matrix metalloproteinases(MMP), caspase , thrombine, or proteosome. The peptide has 9-15 amino acids including Pro-Leu-Gly-Val-Arg (SEQ ID NO: 1), Gly-Asp-Glu-Val-Asp-Ala-Pro(SEQ ID NO: 2), Phe-Pip-Arg-Ser(Pip=pipecolic acid)(SEQ ID NO: 3), Gly-Gly-Arg-Arg-Gly-Gly(SEQ ID NO: 4), Arg, or Lys.
