The technical outlook is promising for miniature analytical systems which are internally complex but externally simple. Salient features to be anticipated are: The use of miniature electrodes or other sensors in combination with enzymes or immunological compounds for biochemical specificity. The use of arrays of miniature electrodes or other sensors. Relatively low cost because of adaptation of semiconductor fabrication techniques. The attendant possibility of the devices being disposable. The intimate involvement of real time computation. The use of simultaneous replicate assays, with increased confidence in the accuracy of the assay. Overall, rapid assays. Because of these possibilities, it may be concluded that the technological outlook for conducting clinical chemistry assays nearer the patient is promising.
