Photothermal cantilever deflection spectroscopy
Microcantilever sensors offer high sensitivity in the detection of adsorbed molecules based either on resonance frequency shift or changes in cantilever deflection, as both of these signals can be detected with very high resolution. Despite the high sensitivity offered by this platform, cantilevers suffer from poor selectivity due to the lack of sufficiently selective interfacial layers which c...
متن کاملPhotothermal deflection spectroscopy and detection.
The theory for a sensitive spectroscopy based on the photothermal deflection of a laser beam is developed. We consider cw and pulsed cases of both transverse and collinear photothermal deflection spectroscopy for solids, liquids, gases, and thin films. The predictions of the theory are experimentally verified, its implications for imaging and microscopy are given, and the sources of noise are a...
متن کاملDYE JET VELOCITY DISTRIBUTION MEASUREMENTS USING PHOTOTHERMAL DEFLECTION SPECTROSCOPY
We demonstrate that photothermal deflection spectroscopy can be used to measure velocity distributions in dye jets. Such measurements are useful in determining the quality of flow in dye jets, The quality of jets is very important for a stable and naanow linewidth operation of dye lasers
متن کاملClustering mechanism of ethanol-water mixtures investigated with photothermal microfluidic cantilever deflection spectroscopy.
The infrared-active (IR) vibrational mode of ethanol (EtOH) associated with the asymmetrical stretching of the C-C-O bond in pico-liter volumes of EtOH-water binary mixtures is calorimetrically measured using photothermal microfluidic cantilever deflection spectroscopy (PMCDS). IR absorption by the confined liquid results in wavelength dependent cantilever deflections, thus providing a compleme...
