Abstract

An optical microscopic apparatus for creating a super-resolution image of an organism or biological matter, the optical microscopic apparatus includes a light source configured to provide visible light including evanescent waves, a hyper-lens unit including a front surface on which a specimen is placed, the hyper-lens unit including a multi-layered structure to convert at least part of the evanescent waves incident on the front surface into propagating waves, an objective lens for collecting visible light emitted from a rear surface of the hyper-lens unit, and an image capturing unit to capture visible light emitted from the objective lens and to create an image of the specimen.

Claims (51)

1. An optical microscopic apparatus for creating a super-resolution image of an organism or biological matter, the optical microscopic apparatus comprising:

a light source configured to provide visible light comprising evanescent waves;

a hyper-lens unit comprising a front surface on which a specimen is placed, the hyper-lens unit comprising a multi-layered structure to convert at least part of the evanescent waves incident on the front surface into propagating waves;

an objective lens for collecting visible light emitted from a rear surface of the hyper-lens unit; and

an image capturing unit to capture visible light emitted from the objective lens and to create an image of the specimen,

wherein the hyper-lens unit is detachable, and

wherein the specimen is cultured on the front surface of the hyper-lens unit while the hyper-lens unit is immersed in a liquid medium for the specimen.

2. The optical microscopic apparatus of claim 1 , wherein the specimen comprises a live organism having a size smaller than one half of a shortest wavelength of the visible light, and

wherein the hyper-lens unit is configured to enlarge an image of the live organism, the image of the live organism when created by the image capturing unit being discernible by a human eye.

3. The optical microscopic apparatus of claim 1 , wherein the specimen comprises a neuron having a size about 150 nm, and

wherein the hyper-lens unit is configured to enlarge an image of the neuron, the image of the neuron when created by the image capturing unit being discernible by a human eye.

4. The optical microscopic apparatus of claim 1 , wherein the specimen comprises at least one organism having a size smaller than one half of a shortest wavelength of the visible light, and

wherein the organism is any one of a deoxyribonucleic acid (DNA), a bacteria, a virus, single molecular cell, and a lipid.

5. The optical microscopic apparatus of claim 1 ,

wherein the hyper-lens unit comprises:

a lens layer having the front surface on which the specimen is placed, the front surface having a concave portion; and

a substrate layer for supporting the lens layer and covering a back side of the lens layer.

6. The optical microscopic apparatus of claim 5 ,

wherein the lens layer has a hemisphere shape by alternately layering a plurality of dielectric layers and a plurality of metallic layers.

7. The optical microscopic apparatus of claim 6 ,

wherein the dielectric layers comprise titanium oxide Ti 3 O 5 , and the metallic layers comprise silver Ag, and

wherein the visible light has wavelengths within a range of 400 nm to 500 nm.

8. The optical microscopic apparatus of claim 6 ,

wherein the dielectric layers comprise silicon Si, and the metallic layers comprise silver Ag.

9. The optical microscopic apparatus of claim 8 ,

wherein the dielectric layers comprise non-crystalline or amorphous silicon formed through sputtering.

10. The optical microscopic apparatus of claim 9 ,

wherein each of the dielectric layers and each of the metallic layers have thicknesses less than or equal to 15 nm, respectively.

11. The optical microscopic apparatus of claim 8 ,

wherein the visible light has wavelengths within a range of 500 nm to 650 nm.

12. The optical microscopic apparatus of claim 1 ,

wherein the hyper-lens unit further comprises a protection film covering the lens layer, the protection film comprising a material for preventing liquid permeation, and

wherein the specimen is configured to be disposed on the protection film.

13. The optical microscopic apparatus of claim 12 ,

wherein the protection film comprises a glass layer.

14. The optical microscopic apparatus of claim 13 ,

wherein the protection film is deposited on the lens layer by an atomic layer deposition.

15. The optical microscopic apparatus of claim 2 ,

wherein the image capturing unit creates video image data including real time movements of the specimen.

16. The optical microscopic apparatus of claim 1 ,

wherein the visible light incident on the hyper-lens unit is non-polarized visible light.

17. The optical microscopic apparatus of claim 1 , further comprising:

immersion oil provided between the objective lens and the hyper-lens unit.

18. A method for creating a high-resolution image of an organism or biological matter, the method comprising:

immersing a hyper-lens unit in a liquid medium for culturing a specimen on one side of the hyper-lens unit, the hyper-lens unit comprising a multi-layered structure to convert at least part of evanescent waves incident on the one side into propagating waves;

creating visible light to illuminate the one side of the hyper-lens unit;

collecting light leaving the other side of the hyper-lens unit; and

obtaining the collected light to create an image of the specimen.

19. The method of claim 18 ,

wherein the specimen comprises a live organism having a size smaller than one half of a shortest wavelength of the visible light, and

wherein the hyper-lens unit is configured to enlarge an image of the live organism, the image of the live organism when created by an image capturing unit being discernible by a human eye.
