National Physical Laboratory



NPL's biosurfaces area covers the surface chemical and physical analysis of materials designed to interface with biological systems.

Such measurements impact and underpin the development of medical and diagnostic devices.


  • Many modern diagnostic tests rely upon the detection of specific biochemical interactions, in which a probe is fixed to the surface and used to capture a target from a biological fluid.
  • The controlled and targeted administration of drugs is extremely important to ensure that patients receive effective doses over the proper period and in the correct location.
  • Accurate quantification of adsorbed biomolecules is important in the design of new biomaterials, diagnostic devices and sensors, as well as for the understanding of biomolecular interactions on surfaces.
