A microcantilever sensor includes a supporting substrate, a cantilever spring element at least partially disposed over the support substrate, a probe layer disposed over the first side of the cantilever spring element, and a piezoresistive transducer attached to the second side of the cantilever spring element. The cantilever spring element is characterized by having a first side and a second side and comprising a polymer having a Young's modulus less than about 100 Gpa,. Sensing systems that incorporate the cantilever sensor of the invention include a detector in communication with the piezoresistive transducer to provide measurements of surface strain changes in the piezoresistive transducer.
