Bacterial infection and inflammation result in massive changes in serum glycoproteins. These changes were investigated by the interaction of the saccharide glycoprotein moiety with lectins. A panel of eight lectins (Canavalia ensiformis, Bandeiraea s

Experimental results are presented which shed light on the properties of thin discontinuous metal films as chemical sensing elements. They demonstrate further some interesting differences between hydrophilic and hydrophobic sensing structures. Two di

Optical characterization of thin porous platinum films has been carried out by spectroscopic ellipsometry in air, in water and in methanol. From the measurements in air, the thicknesses and porosity of the films were determined. The measurements in w

Thin discontinuous (4 and 35 nm thick) platinum films were used as the gate metal of metal-oxide-semiconductor capacitors. It was observed that the metal film acts as a gas permeable structure in electrolyte solutions when the surface was hydrophobic

The scanned light pulse technique applied to gas sensing surfaces is evaluated for some applications. The basis of the technique is briefly described, and also some advantages. It is further described how the thickness of a thin (10–15 nm) metal la

Investigations of the usefulness of molecularly-imprinted polymers in sensor applications were undertaken. Thin polymer membranes containing molecular imprints against l-phenylalanine anilide were prepared and applied as sensing layer in field-effect

Polymer membranes are used to increase the selectivity to certain gases of metal-silicon dioxide-semiconductor (MOS) structures. Other parameters which influence the selectivity of MOS structures are the type of gate metal, its microstructure (dense

The details of a recently demonstrated possibility of making two-dimensional response maps of a gas mixture are discussed. It is described how maps of work-function changes due to the interaction between molecules like ethanol and ammonia and thin ca

THERE is much interest in the use of chemical sensor arrays, in conjunction with pattern-recognition routines, for developing artificial olfactory devices—'electronic noses'—which can characterize the chemical composition of gas mixtures1–5. He

We have earlier demonstrated that thin discontinuous hydrophobic platinum films, used as the gate metal of rnetal-oxide-semiconductor capacitors act as gas permeable structures. In this contribution we describe both a field effect capacitor and a fie
