81Introduction to Nanosensors
during the last two decades. Prime identiable motives for progress in
nanosensors have been the quest for high sensitivity, selectivity, resolution,
repeatability, reliability, desirable hysteresis, and linearity properties in
devices, and to develop subminiature sensors at lower effective costs, yield-
ing high performance-cost ratios. Although probes for scanning and atomic
force microscopes still dominate the commercial nanosensor arena, some
new nanosensors, resulting from multidisciplinary research by high-tech
companies and academic research laboratories, are beginning to make their
way to ...
