Bio sensing method, apparatus and system using graphene oxide

摘要

graphene oxide by using biosensing methods, sensors and systems are provided. ; biosensor according to the present invention, the target substance labeled with metallic particles; And comprising a probe coupled to the graphene oxide material exhibiting fluorescence properties, in the case where the target substance and the probe substance to the combination characterized in that the metal particles of the target material to reduce the fluorescence properties of the graphene oxide and , biosensing method according to the invention, sensors and systems using the unique fluorescent properties of the graphene oxide itself without the use of a dye for staining a target material, it is possible to identify the presence of optically detectable substance. Further, since the synthesis is difficult and cost to avoid use of expensive dyes, biosensing method according to the invention, the sensor and the system is excellent in economical efficiency.
