When the interaction between the substrate and enzyme occurs, it causes a change in the resonant frequency of the crystal; thus, the mass or the surface property of the crystal will be recorded in real time. The sensor was tested using synthetic complementary oligonucleotides (25-mer) and with a noncomplementary oligonucleotide (23-mer). Streptavidin was covalently linked to thiol/dextran modified gold electrodes on which 5′-biotinylated oligonucleotides probes (25-mer), P35S and T-NOS, were immobilized. This shift can be measured electrically to determine the additional mass of the crystal (Velusamy et al., 2010). These techniques have been applied mainly for pathogen detection and fungal pathogens such as Aspergillus niger, achieving high sensitivity (103 cfu ml−1) (Nugaeva et al., 2007). The MOX sensors allowed for discrimination of the samples at 69%, while the respective value for the MS experiment was 100%. Another senor was fabricated by immobilization of 21-mer single stranded oligonucleotide (probes) related to the EPSPS gene onto the gold surface of the electrodes via avidin–biotin interaction. To achieve the required sensitivity an amplification system was used based on the addition of an anti-IgG-horseradish peroxidase enzyme conjugate, which will attach to the anti-AFB1 antibody. Immobilization strategies of probes via thiol (Karamollaoglu et al., 2009; Mannelli et al., 2003a,b), biotin (Mannelli et al., 2003a,b; Minunni et al., 2001), and amino groups (Minunni et al., 2001) have been used for GMO screening.

However, the pesticide carbofuran (a carbamate) can be detected at 1.30 × 10− 9 M with ChE activity inhibited with 5 min incubation, and the sample can be reused five times (Kim et al., 2007). The 35S CaMV promoter and the T-NOS terminator, discussed earlier, are the common transgenic elements used as screening test for GMOs. Most of the sequences applied for biosensors were amplified using PCR, a method that requires known precise nucleotide sequences flanking both the ends of the target region of DNA. Mass-sensitive biosensors are rather popular due to high sensitivity. Malheureusement non, et méfiez vous les QCM sont souvent plus durs que les sujets classiques. Cantilever technology was initially used in atomic force microscopy (AFM), but more recently microfabricated cantilever has been produced as a promising technology in bio-sensing applications (Waggoner and Craighead, 2007). There are many commercial versions of the QCM device (e.g., www.Q-Sense.com) including some to detect the initial adhesion of bacteria to stainless steel surfaces.
