    • PURPOSE: An antivirus activated compound screening method is provided to screen the derivatives of the zanamivir or the oseltamivir with a new structure promptly. CONSTITUTION: A compound screening method with anti-virus activity comprises a step that attaches neuraminidase antigen to a carbon nanotube semiconductor device sensor; a step that attaches a silicon well on the channel region of the carbon nanotube semiconductor sensor on which neuramidase antigen is attached; a step that applies gate voltage after adding a reaction buffer solution in the silicon well of a carbon nanotube semiconductor device sensor that is installed on the stage unit of probe station; and a step that checks the change in electrical conductivity. The attachment of neuraminidase on the carbon nano tube semi conductor device sensor has a linker selected from a group of 1-pyrene butanoic acid, succinimidyl ester, and the biotin and gold nanoparticle as mediation. The gate voltage is within the range of -1 Volt to +1 Volt. The neuraminidase antigen is originated from the novel influenza flu virus.
