CMOS-Integrated Film Bulk Acoustic Resonators for Label-Free Biosensing

Sensors, 2010
The throughput is an important parameter for label-free biosensors. Acoustic resonators like the quartz crystal microbalance have a low throughput because the number of sensors which can be used at the same time is limited. Here we present an array of 64

Quartz Crystal Microbalance a Powerful Technique for Nanogram Mass Sensing

Eurasian Journal of Science and Engineering, 2022
A quartz crystal microbalance (QCM) is an acoustic transducer that sends an electronic signal when a mass change is detected on the sensor surface of an oscillating quartz-crystal resonator.

The effect of SU-8 patterned surfaces on the response of the quartz crystal microbalance [PDF]

, 2004
In this work we present data showing the effect of patterning layers of SU-8 photoresist on a quartz crystal microbalance (QCM) and subsequent chemical treatment to increase their hydrophobicity. Patterns with 5 mu m diameter pillars spaced every 10 mu m

Oscillator for Biosensors based on Quartz Crystal Microbalance (QCM)

Revista Facultad de Ingeniería Universidad de Antioquia, 2012
Quartz crystal is generally used in some applications as a microbalance taking advantage of its capacity to change the resonance frequency according to any surface mass change on the resonator. In this way a quartz crystal can be used as a transducer in
