QCM Real-Time Sensor for monitoring of Poisonous Cyanide from Drinking Water and Environmental

The dyes resulted from textile industry are pollutants from POPs category which are responsible for wastewaters color and other environmental problems. Quartz crystal microbalance (QCM) allows the determination of dyes concentration values due to the high sensitivity of resonant crystal frequency. The obtained experimental results lead to the conclusion that the QCM method can be successfully used to obtain an accurate quantitative and qualitative analysis of dyes in wastewaters in real time.

“…In a similar approach using nano-sized silver particles a detection limit of 2.2 g/l was stated [18]. Using unmodified QCM gold electrodes detection limits of about 50 g/l potassium cyanide after 10 min analysis time and 2 g/l after 20 min analysis time [19] as well as 16.1 and 2.7 g/l for analysis times of 10 min and 1 h, respectively, were achieved [20]. Cyanide also promotes the disproportionation of Hg(I) and the consequent amalgamation of the mercury onto the gold electrodes leads to a frequency decrease.…”

“…Another advantage of QCM over other endpoint measuring tools is its ability to make real-time measurements. This feature provide it the potential of usage in automated continuous monitoring systems [ 33 ]. Making real-time measurements also makes it a suitable system for characterization of affinity-based systems, surfaces, and recognition elements [ 32 ].…”

Ochratoxin A (OTA) is a potent mycotoxin that poses a risk in food and feed moieties and subject to worldwide regulation. Laboratory-based analytical methods are traditionally employed for reliable OTA quantification, but these methods cannot provide rapid and on-site analysis, where biosensors fill this gap. In this study a label-free quartz crystal microbalance (QCM)-based immunosensor for the detection of OTA, which is one of the most important small molecule contaminants, was developed by direct immobilization of OTA to amine-bearing sensor surfaces using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC)/N-Hydroxysuccinimide (NHS) chemistry. The protein-free sensor surface enabled regeneration of sensor surface with 50 mM NaOH and 1% SDS up to 13 times without loss of performance, which would disrupt a protein-containing sensor surface. We developed a QCM immunosensor using the developed sensor surface with a 17.2–200 ng/mL detection range which can be used for on-site detection of feedstuffs.
