Patent Category: 


Method to directly pattern antibodies onto a glass surface


Key Features: 

  • Antibodies are adsorbed tightly enough on the surface to allow multi step processes.
  • Method can be used to pattern any protein by patterning its anti-antibody.
  • Approach can also be directly exploited to selectively bind cells to a surface and employed in cell sorting assays or cellular studies, without the need of surface pretreatment.
  • Antibodies retain their activity after being directly patterned over a glass surface using photolithography.


  • Manufacturing biosensors, antibody based assays and the companies involved in cell sorting (sperm selection) for animal husbandry.
  • Electron beam lithography
