Clamp-type quartz tuning fork enhanced photoacoustic spectroscopy

Optics Letters, 2022
In this Letter, clamp-type quartz tuning fork enhanced photoacoustic spectroscopy (Clamp-type QEPAS) is proposed and realized through the design, realization, and testing of clamp-type quartz tuning forks (QTFs) for photoacoustic gas sensing. The clamp-type QTF provides a wavefront-shaped aperture with a diameter up to 1 mm, while keeping Q factors >

Quartz tuning fork biosensor

Biosensors and Bioelectronics, 2002
The use of quartz tuning forks for biosensor applications is investigated. The basis of the sensor is to coat the tuning fork surfaces with specific biomolecules and measure subsequent mass loading from the selective binding of complementary analytes. Two experimental set-ups are evaluated, direct mechanical excitation and self-excitation.
