21. Chemical and Biological Sensors Based on Microcantilevers.

Author

Yurish, Sergey Y., Gomes, Maria Teresa S. R., Datskos, P. G., Lavrik, N. V., and Sepaniak, M. J.

Abstract

The recent developments in micro-mechanical or micro-electro-mechanical (MEMS) systems have enabled the use of new transduction modes that involve mechanical energy and are based primarily on mechanical phenomena. As a result, an innovative family of chemical and biological sensors has emerged. In this work we discuss the recent advances in cantilever transducers. While MEMS represents a diverse family of designs, devices with simple cantilever configurations are especially attractive as transducers for chemical and biological sensors. We discuss four important aspects of cantilever transducers, which include operation principles and models, figures of merit, and applications. We also provide a brief analysis of historical predecessors of the modern cantilever sensors. Keywords: microcantilever, MEMS, micromechanical, resonance, deformation, transducer, stress, chemical sensor, biosensor, analyte, response mechanism, noise, thermomechanical, figures of merit.

40. Antibody-Based Fiberoptics Biosensor for the Carcinogen Benzo(a)pyrene

Author

Vo-Dinh, T., Tromberg, B. J., Griffin, G. D., Ambrose, K. R., Sepaniak, M. J., and Gardenhire, E. M.

Abstract

A new antibody-based fiberoptics biosensor was used to detect the important carcinogen benzo(a)pyrene (BaP). The fiberoptics sensor utilizes anti-BaP antibodies covalently bound to its tip. A helium cadmium laser was used as the excitation source to induce fluorescence from BaP conjugated to the bound anti-BaP antibodies. The fiberoptics device can detect 1 femtomole of BaP in a 5-μL sample drop.

42. Immunosensors: Principles and Applications

Author

Vo-Dinh, T., Sepaniak, M. J., Griffin, G. D., and Alarie, J. P.

Abstract

This paper presents an overview of the principles and applications of immunofluorescence spectroscopy in the development of antibody-based fiber-optic sensors. Special focus is devoted to antibody-based fiber-optic fluoroimmunosensors developed in our laboratories to detect important pollutants and biochemicals. The fiber-optic sensor utilizes antibodies covalently bound or encapsulated on the probe tip. The usefulness of fluoroimmunosensors for environmental and biomedical monitoring is discussed.Copyright 1993, 1999 Academic Press
