Abstract
A sensor device (1-5) has a sensing surface on which, in use, first molecules (5) are immobilized. The first molecules (5) are capable of interaction with second molecules which may be present in a sample of fluid applied to the sensing surface, such interaction resulting in a measurable change of some physical property of the sensor device. The sensing surface is coated with a layer (4) of diamond-like carbon to protect and preserve the integrity of the sensing surface.
Claims19
A sensor device for detecting the binding of first molecules to second molecules, said sensor device comprising:
- a sensor surface,
- said sensor surface having an impervious layer of diamond-like carbon (DLC) applied thereto, and
- said impervious layer having first molecules immobilized thereon,
- wherein contact of a sample containing said second molecules with said sensor device results in binding between said first molecules and said second molecules.
