A biosensor for detection of DNA sequences based on a 50MHz QCM electronic oscillator circuit

Abstract: This work deals with the development of a high sensibility DNA biosensor based on a 50MHz Quartz Crystal Microbalance (QCM) Oscillator Electronic Circuit. The designed QCM oscillator sensor is able to detect the presence of complementary DNAs in a solution that match the sequence on a given strand in function of the changes in the output frequency of the oscillator. The design is adapted so that the Barkhausen condition is satisfied even when the quartz is immerged in liquid media. Also a comparative study of … Show more

“…However, in spite of the efforts carried out to design oscillator configurations suitable for in-liquid applications 43-51 the poor stability of high frequency QCM systems based on oscillators has prevented increasing the limit of detection despite the higher sensitivity reported. [52][53][54][55][56] A higher sensitivity is necessary when a higher resolution is required. This happens in those applications where very tiny changes in the sensor resonant frequency, due to the perturbation process to be monitored, are expected.…”

“…For example, Cheng et al [11] presented a DNA detection system that includes a DNA biosensor, a current amplifier circuit for DNA identification via electrical detection; the lowest detectable concentration of the DNA target on this device is 0.1 nM. The development of a highsensibility DNA biosensor based on a 50 MHz quartz crystal microbalance (QCM) oscillator electronic circuit was reported by Bustabad et al [9]. In this study, one 50 MHz QCM oscillator circuit was designed and simulated using SPICE, which was implemented on a printed circuit board.…”

“…It has been widely used as a powerful analytical tool in medical diagnostics [1À3], environmental testing [4À6] and food analysis [7]. In principle, a biosensor is fabricated by attaching a bio-receptor such as DNA probes, enzymes, antibodies or cells on the surface of a suitable transducer, which can convert a biological response into an electrical [3,4,8], optical [2] or mechanical [1,7,9] signal. As previously mentioned [10], the signal processor plays an important role in the DNA sensor.…”

“…[Bustabad et al 2009;Stehrer et al 2009a;Uttenthaler et al 2001a]. Este capítulo comprende el diseño de un oscilador que mejore las prestaciones de los desarrollados hasta el momento para entorno líquido, permitiendo aumentar las aplicaciones, la sensibilidad en la medida y sirviendo, al mismo tiempo, como plataforma para implementar sistemas de HFF-QCM.…”

“…En consecuencia, tanto los resultados obtenidos, como la propia filosofía de operación de los osciladores parecen demostrar que no son la mejor técnica para la caracterización de HFF-QCM. No obstante, es el único método que se utiliza en la actualidad [Bustabad et al 2009;Stehrer et al 2009b;Uttenthaler et al 2001b].…”
