| description | The invention relates to a micro-ring resonant cavity biosensor based on nanogold labeled antibody enhancement and a use method of the micro-ring resonant cavity biosensor. Relates to the technical field of biosensing detection, the nanogold labeled antibody enhancement-based micro-ring resonant cavity biosensor comprises a micro-ring resonator and a micro-ring chip structure, the micro-ring resonator is an up-and-down type double micro-ring resonator, and the up-and-down type micro-ring resonator can be provided with two input or output ports; according to the invention, the nano-gold labeled antibody further enhances the resonance spectrum change caused by the capture of the antigen on the micro-ring structure; when the refractive index change caused by the ultralow-concentration antigen around the micro-ring structure is not enough to cause the micro-ring resonance spectrum change or a spectrograph cannot detect the micro-ring resonance spectrum change caused by the tiny refractive index change, the amplif |
