Structure, localized surface plasmon resonance sensor chip, and localized surface plasmon resonance sensor, as well as methods for their preparation

摘要

It may provide a localized surface plasmon resonance sensor more sensitive, to realize the localized surface plasmon resonance sensor chip. And a cylindrical body and flat portion, the tubular body is provided upright opening to face to the plane of the flat portion, the structure according to the present invention, the opening of the cylindrical body The average inner diameter is in the range of 5nm or less 2,000nm, and the ratio of the inner diameter A of the opening of the cylindrical body, and the inner diameter B at the midpoint of the depth from the opening of the cylindrical body (A / B) is in the range of 1.00 to 1.80, and is characterized in that the bottom of the cylindrical body is non-spherical.
