Photothermal spectroscopy of Bacillus anthracis and Bacillus cereus with microcantilevers
چکیده انگلیسی

Microcalorimetric optical and infrared spectroscopy is a method of determining the spectral absorption of small quantities of materials over a wide range of incident wavelengths. In this paper, the first spectroscopic results for microcantilevers coated with Bacillus anthracis (BA) are presented. These results, for B. anthracis from 2.5 to 14.5 μm, are compared with results from microcantilevers coated with Bacillus cereus (BC) and standard spectroscopic absorption data. The results demonstrate strong correlation between the deflection measurements and the reference spectroscopic absorption peaks. An advantage of this microcantilever-based method over traditional spectroscopy is that much smaller amounts of material (nanogram quantities) can be detected in comparison with the milligram amounts needed for standard methods. Another advantage is that the complete system can be relatively small without sacrificing spectral resolution.
