Neuroscience Letters, 1999
Acoustic neurinomas were sequentially extracted with saline and saline-Triton X-100 buffers. Detergent was required to detach the bulk of acetylcholinesterase (AChE), but butyrylcholinesterase (BuChE) was mostly released with saline buffer. Sedimentation analysis and hydrophobic chromatography revealed that neurinomas contain principally amphiphilic ...

Microporous Materials, 1993
Microporous thin films composed of a molecular coupling layer, zeolite crystals, and a porous silica overlayer, were formed on the gold electrodes of quartz crystal microbalances (QCMs). The silica overlayer enhances the mechanical stability of the zeolite films, and results in additional surface area and porosity as characterized by the sorption ...

Optically detected acoustic paramagnetic resonance in molecular crystals
Chemical Physics Letters, 1973Abstract The optically detected acoustic paramagnetic resonance of the metastable triplet state of 1,2,4,5-tetrachlorobenzene (TCB) in zero field is reported. The spin-phonon interaction in molecular crystals is discussed in terms of the direct process single phonon absorption by the paramagnetic spin system.

Molecular recognition of neurotransmitter GABA using acoustic sensors
Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002The conventional detection methods for neurotransmitter /spl gamma/-aminobutyric acid (GABA) are concentrated on HPLC and enzymatic reactions. We report here a novel acoustic immunosensor for dynamic measurement of GABA in buffer solution using an immunohistochemical strategy. The adsorption process of anti-GABA on a well-defined gold electrode surface

Acoustic fingerprints of photoacoustic contrast agents for molecular imaging
SPIE Proceedings, 2007Protein nanospheres capable of frequency controlled oscillation in response to laser stimulation are presented as contrast agents for photoacoustic imaging. Incident laser energy absorbed by dye-labeled protein nanospheres causes thermoelastically generated sound production.

Transverse Acoustic Modes of Coherent Molecular Motions in Tetracene Crystals
The Journal of Physical Chemistry LettersMolecules in organic crystals, akin to atoms in inorganic lattices, can act as rigid units whose vibrations mediate thermal transport. While collective molecular motions are expected to generate coherent vibrational modes, including longitudinal acoustic (LA) and transverse acoustic (TA) modes, the coherent excitation of TA modes in molecular crystals ...

The measurement of molecular orientation in fibers by acoustic methods
Journal of Applied Polymer Science, 1960AbstractIn the present work, the sound velocity in polymeric fibers or film strips is related to a quantitative measure of molecular orientation in the sample. It is shown that this measure of orientation can be calculated from two experimental quantities: the sound velocity in an oriented specimen and the velocity in a randomly oriented sample.

Acoustic Biosensors for Noninvasive Imaging of Molecular Processes
Understanding biology in its native context has been a major scientific endeavor. Yet, it is challenging to visualize cellular dynamics at the molecular scale in the context of a living organism at the macroscopic scale. Ultrasound imaging represents a promising candidate to address this challenge, with its unique advantages of large imaging volume ...openaire +1 more source
