Selective plasma activation of surfaces for biosensing application

Different gas plasma can be used for creating specific surface chemical bonds on material surfaces. These bonds can then be utilized for detection of different chemicals and biomolecules. Biosensors are currently being used for a variety of sensing ranging from medical diagnosis, drug development, food industry and environmental monitoring. The bio analyte is detected by the interaction with the biological element like protein, DNA, peptide, etc. on the surface of the sensor and the signal is transmitted as a electrical, mechanical or optical one. There is a growing demand to develop biosensing surfaces that can be easily integrated with electronics to make highly efficient analytical devices.
