Non-specific binding based sensing

In the urge for sensitivity most current biosensors focus on collecting signals from specific binding events – between target analyte and its corresponding receptor. The constant hurdle is to overcome the background noise, or the nonspecific interaction, which more often than not, masks the desired output signal. By working with a multitude of weak interactions, a surface with various functional groups can differentiate analytes with distinct physical and chemical characteristics, as the weak, nonspecific interactions give out a particular fingerprint profile.
