摘要：

A set of amperometric, impedimetric, potentiometric and reference thin-film metal electrodes (TFMEs) in silicon technology, which may be combined in different shapes and sizes, has been constructed as transducers for biosensors. The chips inserted in test strips or flow-through devices are covered by the enzyme included in surface-crosslinked polyurethane layers. Improved selectivity for glucose, lactose, lysine and urea sensors as well as reduced protein adsorption from real blood samples have been achieved by using chemically modified polymer surfaces.
