摘要

PURPOSE: A mass reinforcing method of gold nano-particles due to light irradiation, a biosensor, and biomolecule combining detection method using the same are provided to reinforce mass of the gold nano-particles by using an optical irradiation method.;CONSTITUTION: A mass reinforcing method of gold nano-particles due to light irradiation comprises the following steps: irradiating a mixture including gold nano-particles(13) and reinforcing metal component(15) with light; and increasing the mass of the gold nano-particles by reducing thereof on the surface of the gold nano-particles. The light is ultraviolet ray. The metal reinforcing component is metallic ion. A bio molecular combining detection method comprises the following steps: reacting target bio molecular with bio sensors which detect physical property changes according to bondage of the target bio molecular; combining the gold nano-particle to the target bio molecular; dipping the bio sensor into a mixture which includes the metal reinforcing components and irradiating light; and detecting physical property change of the gold nano-particles.;COPYRIGHT KIPO 2012
