Fast and sensitive detection of mycotoxins in wheat using microfluidics based Real-time Electrochemical Profiling

Detection of bacterial concentration variations based on dielectric magnetic flux

“…Suppose that the system has similar surface and current. The magnetic flux simplifies the electric field and frequency (Alves et al, 2015;Olcer et al, 2014). As previously indicated, changing the electric field inside the dielectric can affect the electric field inside.…”

Mycotoxin Determination in Foods Using Advanced Sensors Based on Antibodies or Aptamers

“…Despite the cross-reactivity of 3-Ac-DON, it met the sensing requests of the DON-contaminated food samples. Based on real-time electrochemical profiling (REP), an electrochemical immunosensor was fabricated coupled with microfluidics system for DON determination in wheat grain [95]. The integrated microfluidic system can allow multiplexed amperometric sensing.…”

Electrochemiluminescence modified electrodes based on RuSi@Ru(bpy)32+ loaded with gold functioned nanoporous CO/Co3O4 for detection of mycotoxin deoxynivalenol

“…The linear equation was I ECL = 3939.66-1430.69 logc, and the correlation coefficient was 0.9968. Compared with the detection limit for electrochemical analysis in real time (REP) (6.25 ng/ml)(Olcer et al 2014), electrochemical immunosensors (64 ng/mL)(Romanazzo et al 2010), and surface plasmon resonance (SPR) sensor (2.5 ng/mL)(Schnerr et al 2002) the proposed ECL modified electrodes has lower detection limit. The lower detection limit may becaused by two factors: (1) the excellent conductivity and catalytic activity of NPCo/Co 3 O 4 -Au nanocomposites could greatly improve the ECL signal; (2) the large specific surface area of NPCo/Co 3 O 4 could fix a large amount of Au NPs and RuSi@Ru(bpy) 3 2+ .…”
