The sensitivity of microcantilevers for measuring intermolecular forces, the commercial availability of cantilevers, and their fabrication using standard microelectronic technology resulted, around 1994, in a new type of sensor where the transducer system is based on a silicon microcantilever with a tipless free end (Figure 10 .6) (Gimzewski et al., 1994; Chen et al., 1995) . Biochemical applications for this type of sensor have been specifically developed for bending-based modes of measurement, with an optical read-out, due to the complexity required for working with the dynamic mode in liquids. Currently, there are many different and alternative ways to increase the sensitivity of cantilever-based biosensors, depending on the sensor working mode.	./cache/cord-022037-4ik3jxjy.txt	./txt/cord-022037-4ik3jxjy.txt
