Biosensors are self-contained analytical devices in which a bioreceptor is integrated with a
transducer. The interaction between the bioreceptor and a target analyte generates a signal suitable for
analytical purposes. In electrochemical biosensors, a change in the redox state of the biorecognition/analyte
system generates a change in an electrochemical quantity which can be monitored by electroanalytical
techniques. Electrochemical sensors can also be miniaturized using ultramicroelectrodes and nanoelectrodes
and their arrays as transducers. These devices are characterized by high specificity and sensitivity and improved
detection limits. Within the frame of the TRANS2CARE project, the Laboratory of Electrochemical Sensors
(http://lsegroup.wix.com/website-lse-group) of the University Ca’ Foscari of Venice is collaborating with some
of the project partners in order to develop bioelectrochemical sensors/nanosensors for clinical/molecular
diagnostics.
