Abstract

A SERS unit comprises an integrally formed handling board and a SERS element secured within a container space provided in the handling board so as to open to one side in a thickness direction of the handling board. The SERS element has a substrate arranged on an inner surface of the container space and an optical function part formed on the substrate, for generating surface-enhanced Raman scattering.

Claims

1. A surface-enhanced Raman scattering unit comprising:

an integrally formed handling board;

a surface-enhanced Raman scattering element secured within a container space provided in the handling board so as to open to one side along a thickness direction of the handling board;

wherein the surface-enhanced Raman scattering element has;

a substrate arranged on a bottom surface of the container space; and

an optical function part formed on the substrate, for generating surface-enhanced Raman scattering,

wherein the substrate is secured to the bottom surface, and is interposed between the bottom surface and the optical function part, and is spaced from a side surface of the container space;

a bag-shaped package packing the handling board before use, and configured to irreversibly expose the container space when used, wherein the inside of the bag-shaped package is vacuumed before use; and

a member having an outer side surface extending along the thickness direction and positioned outside the optical function part as seen in the thickness direction, wherein the outer side surface faces an inner surface of the handling board.

2. A surface-enhanced Raman scattering unit according to claim 1, wherein the container space is a space within a depression provided on a principal surface on the one side of the handling board.

3. A surface-enhanced Raman scattering unit according to claim 1, wherein the container space is a space on the inside of a ring-shaped wall part integrally formed on a principal surface on the one side of the handling board.

4. A surface-enhanced Raman scattering unit according to claim 1, wherein the member is a securing member for mechanically securing the surface-enhanced Raman scattering element within the container space, and further comprising a cover arranged on the handling board so as to cover an opening of the container space.

5. A surface-enhanced Raman scattering unit according to claim 4, wherein the cover is light-transmissive.

6. A surface-enhanced Raman scattering unit according to claim 4, wherein the cover is arranged within a widened part provided in the opening and is restrained from moving in a direction perpendicular to the thickness direction.

7. A surface-enhanced Raman scattering unit according to claim 4, wherein the cover is arranged on the inside of a projection integrally formed around the opening so as to surround the opening as seen in the thickness direction and is restrained from moving in a direction perpendicular to the thickness direction.

8. A surface-enhanced Raman scattering unit according to claim 1, wherein the handling board is integrally formed from a resin.

9. A surface-enhanced Raman scattering unit according to claim 8, wherein the resin has a light-absorbing color.

10. A surface-enhanced Raman scattering unit according to claim 1, wherein the member is a cover arranged on the handling board so as to cover an opening of the container space.

11. A surface-enhanced Raman scattering unit according to claim 10, wherein the cover is light-transmissive.

12. A surface-enhanced Raman scattering unit according to claim 10, wherein the cover is arranged within a widened part provided in the opening and is restrained from moving in a direction perpendicular to the thickness direction.

13. A surface-enhanced Raman scattering unit according to claim 10, wherein the cover is arranged on the inside of a projection integrally formed around the opening so as to surround the opening as seen in the thickness direction and is restrained from moving in a direction perpendicular to the thickness direction.
