Selective area growth devices

Secondly, the demonstration that biomolecules in the form of antibodies can be used to cause surface binding to specific antigens tremendously enhances the selective detection capability of these devices. Applications are now possible not only in the traditional areas of immunoassay (e.g. clinical analysis) but also to any analytical problem where a biomolecule can be developed to selectively bind to the analyte of interest. Earlier chapters have reviewed the possibilities of biological detection which are now applicable to piezoelectric sensors. Thus one should expect a great deal of growth in the development of these devices as the field matures.
