Abstract
The present application discloses a detection device including a light source configured to emit emission light, a scattering substance situated near a target object and configured to generate plasmon resonance between the scattering substance and the target object, a light guide portion configured to guide the emission light to the scattering substance and cause first reflected light, which is reflected from the scattering substance, and a detector configured to detect a state in phase of the first reflected light.

1-13. (canceled)
A detection device, comprising:
- a light source configured to emit emission light;
- a scattering substance situated near a target object and configured to cause plasmon resonance between the scattering substance and the target object;
- a light guide portion configured to guide the emission light to the scattering substance and cause first reflected light which is reflected from the scattering substance;
- and
- a detector configured to detect a state in phase of the first reflected light,
- wherein the light guide portion guides the emission light to the target object to cause second reflected light which is reflected from the target object, and
- wherein the detector detects a state in phase of the second reflected light.
A detection method, comprising steps of:
- emitting emission light;
- guiding the emission light to a scattering substance situated near a target object to reflect the emission light from the scattering substance and cause first reflected light;
- guiding the emission light to the target object to cause second reflected light which is reflected from the target object;
- and
- detecting a state in phase of the first reflected light and the second reflected light based on plasmon resonance between the target object and the scattering substance.
