BIOSENSORS FOR DETECTING BOND RUPTURE

摘要

A biosensor comprises a surface onto which bio-macromolecules are bound, the surface and bio-macromolecules being immersed in liquid, a bond rupture detector associated with the surface and arranged to detect the rupture of bonds between the bio-macromolecules and a target substance ( 6 ), and an oscillator ( 8 ) associated with the liquid and spaced from the surface and arranged to produce oscillations in the liquid to cause bonds between the bio-macromolecules and the target substance ( 6 ) to rupture.
