Method for cutting a biological sample and a device used therefor

Abstract

An object of the present invention is to provide a method which comprises adhering a biological sample to a film, cutting out a target area of the sample, and then peeling off the film to collect the fragment which was cut out, wherein the operability is good and a cutting sharpness in cutting by a laser beam is good. The present invention provides a method for cutting a biological sample by light irradiation, which comprises locating the biological sample and a colored film having a thickness of 3 to 6 μm onto one side of a support, and irradiating the biological sample with a light beam, thereby cutting out a target area of the biological sample.

1 . A method for cutting a biological sample by light irradiation, which comprises locating the biological sample and a colored film having a thickness of 3 to 6 μm onto one side of a support, and irradiating the biological sample with a light beam, thereby cutting out a target area of the biological sample.  
     
     
         2 . The method according to  claim 1  wherein the biological sample is irradiated with a light beam from the other side of the support which is opposite to the side holding the biological sample.  
     
     
         3 . The method according to  claim 1 , wherein the biological sample is living tissue fragments, cells, chromosomes or microorganisms.  
     
     
         4 . The method according to  claim 1 , wherein the light beam is a laser beam.  
     
     
         5 . The method according to  claim 4 , wherein the light beam is an ultraviolet laser beam.  
     
     
         6 . The method according to  claim 1 , wherein the support is a glass support.  
     
     
         7 . The method according to  claim 1 , wherein the colored film is an aramid film.  
     
     
         8 . The method according to  claim 1 , wherein the colored film having a thickness of 3 to 6 μm is located on one side of the support and the biological sample is located on the film.  
     
     
         9 . The method according to  claim 1 , wherein the cutting out of a target area is carried out under microscopic view.  
     
     
         10 . A method for cutting and collecting a biological sample, which comprises cutting out the biological sample by the method according to  claim 1 , and then collecting the sample which was cut out.  
     
     
         11 . A device for cutting a biological sample, wherein a colored film having a thickness of 3 to 6 μm is located on one side of a support.  
     
     
         12 . The device according to  claim 11 , wherein the support is a glass support.  
     
     
         13 . The device according to  claim 11 , wherein the colored film is an aramid film.
