“…Similar trends were also observed by other scientist [2,[5][6][7] for sucrose and glucose solution. We also found that sucrose gave a higher frequency change compared to glucose and maltose for both 9 and 10 MHz QCM.…”

Abstract:A device was constructed to monitor viscosity of solutions using fundamental frequency of 9 MHz and 10 MHz quartz crystal. Piezoelectric quartz crystals with gold electrodes were mounted by O-ring in between liquid flow cell. Only one side of the crystal was exposed to the solutions which were pumped through silicon tube by a peristaltic pump. The measured frequency shift was observed in order to investigate the interfacial behavior of some selected solution in contact with one surface of Quartz Crystal Microbalance (QCM). An analysis of the interaction between an AT-cut quartz crystal microbalance and various liquid system of analytical interest is presented. The analysis which includes piezoelectric effects and other influences; liquid properties, experimental conditions and the characteristic of the solution are reported. Oscillation in distilled water is taken as a reference. The frequency change caused by the density ( , gcm 3 ) and viscosity ( , gcm 1 s 1 ) were found to be proportional to the square root of the product, ( ). The result suggested that analysis of small frequency shifts during EQCM studies needs to account for changes in and of the solution.Generally, all the liquid tested showed an increment of the frequency shift with increasing content of solutes. For each solution, the frequency was recorded as the concentration increases from distilled water to a very concentrated solution. The frequency measurements carried out for saccharide solution produces the maximum changes of frequency shift compared with other solutions.

“…8 Another viscometer is based upon a rod, under constant force, traveling inside a fluid-filled tube with the viscosity determined from the time of travel. 9 Piezoelectric transducer ceramics, 10 ultrasonic plate waves, 11 and quartz resonators 12,13 have also been used for viscosity measurements. These methods all require direct electrical connections to the sensor.…”

A ribbon-like magnetoelastic thick-film sensor can be considered the magnetic analog of an acoustic bell. In response to an externally applied magnetic field impulse the magnetoelastic sensor magnetically rings, in a bell-like fashion, emitting magnetic flux with a characteristic resonant frequency that is determined from a fast Fourier transform of the transient response captured using a pickup coil. The resonant frequency of the sensor changes in response to mass loading and, when immersed in liquid, interfacial shear forces associated with viscosity. We report on the use of magnetoelastic sensors to measure the viscosity and density of highly viscous liquids. When characterizing highly viscous liquids, to avoid over damping of the sensor due to the liquid mass load the sensor is suspended from a boat-like structure with one end of the sensor immersed a fixed distance into the liquid. Using this method liquid viscosities ranging from 1.3 to 12 P are measured.

“…Analyte or any other mass bound on surface of crystal or more precisely on surface of electrodes located on the crystal results in change of oscillation frequency [ 13 ]. The change (decay) in frequency is proportional to mass bound the crystal as described by Sauerbreay and coworkers [ 14 , 15 ] but change in medium viscosity can also influence the oscillations as defined by Kanazawa and coworkers [ 16 , 17 ].…”

Piezoelectric biosensors are a group of analytical devices working on a principle of affinity interaction recording. A piezoelectric platform or piezoelectric crystal is a sensor part working on the principle of oscillations change due to a mass bound on the piezoelectric crystal surface. In this review, biosensors having their surface modified with an antibody or antigen, with a molecularly imprinted polymer, with genetic information like single stranded DNA, and biosensors with bound receptors of organic of biochemical origin, are presented and discussed. The mentioned recognition parts are frequently combined with use of nanoparticles and applications in this way are also introduced. An overview of the current literature is given and the methods presented are commented upon.
