▎ 摘　　要

NOVELTY - A gene amplifying and detecting device, comprises: a gene amplifying chip including a chamber formed in it; a reaction solution filled in the chamber and including a fluorescent material; a light source located at one side of the gene amplifying chip; a light detector located at the other side of the gene amplifying chip; and graphene heaters formed on inner or outer surfaces of the gene amplifying chip so as to heat the reaction solution. USE - The device and method are useful for amplifying and detecting gene (claimed). ADVANTAGE - The device performs thermal-cycling to amplify genes using a graphene heater and detects the genes through an optical path which is transmitted through the graphene heater and a reaction solution. Also, the device is cost-effective and has low power consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of amplifying and detecting a gene, comprising: filling a reaction solution including a fluorescent material in a chamber formed in a gene amplifying chip; heating the reaction solution using a graphene heater formed on an inner or outer surface of the gene amplifying chip and performing thermal-cycling of the reaction solution; supplying incident light from a light source located at one side of the gene amplifying chip; detecting emitted light by a light detector when the incident light is transmitted through the graphene heater and the reaction solution, the transmitted light is adsorbed into the fluorescent material included in the reaction solution, and the adsorbed light excites the fluorescent material to emit the emitted light; and measuring an amount of amplified gene products from the detected emitted light.
