METHOD FOR PREPARING METAL NANOSTRUCTURE BASED ON BIOMOLECULES

摘要

The present invention relates to a method for preparing metal nanostructures using DNA, and more particularly, to a method for preparing metal nanostructures, in which a self-assembling DNA is used as a frame, and thus the orientation, shape and size of the nanostructures are easily controlled compared to conventional bottom-up methods. Metal nanostructures prepared by the method show excellent localized surface plasmon resonance properties, and thus can be used as fluorescent substances in drug delivery, biomedical imaging, supersensitive biosensors, etc.

1. A method for preparing a biomolecule-based metal nanostructure, the method comprising the steps of:
(a) forming a self-assembled monomolecular layer of a biomolecule on the surface of a metal nanoseed, thereby forming a metal nanoseed-biomolecule complex; and (b) growing a metal ion on the surface of the complex while reducing the metal ion with a reducing agent.
