“…Voltammetric technique has high sensitivity, selectivity and reproducibility with fast response and low cost [41] and thus proved to be an emerging choice for the scientists working in the analytical field. Various types of electrodes with different types of surface modifications have been used as a working electrode in the electrochemical analysis of MEL including carbon paste electrodes [42], carbon disc electrode [43], boron-doped diamond (BDD) electrode [44], manganese hexacyanoferrate (MnHCF) mixed-valent poly (3, (PEDOT) hybrid film modified glassy carbon electrode [45], BT-drug membrane sensors [46], glassy carbon electrode [47], RGO/RuO2/GCE [48] etc.…”

“…The comparison of this work with others (Agrawal et al, 2013;Devaraj, Deivasigamani, Jeyadevan, 2013;Moreira, Freitas, Sales, 2011) showed the advantage of GO added. This research demonstrate again that GO is an excellent modification material in voltammetric sensor.…”

“…By comparison, electrochemical method is less expensive and has additional advantages, such as fast response speed, simple operation, timesaving, high sensitivity, and real-time detection in clinical and drug control. Based on these reasons, some electrochemical methods for determination of NFX were developed more recently (Agrawal et al, 2013;Devaraj, Deivasigamani, Jeyadevan, 2013;Moreira, Freitas, Sales, 2011). Shim and co-workers (Agrawal et al, 2013) used a multi-walled carbon nanotube (MWCNT) modified pyrolytic graphite (MPG) electrode for determination of NFX.…”

In this approach, a new voltammetric method for determination of norfloxacin was proposed with high sensitivity and wider detection linear range. The used voltammetric sensor was fabricated simply by coating a layer of graphene oxide (GO) and Nafion composited film on glassy carbon electrode. The advantage of proposed method was sensitive electrochemical response for norfloxacin, which was attributed to the excellent electrical conductivity of GO and the accumulating function of Nafion under optimum experimental conditions, the present method revealed a good linear response for determination of norfloxacin in the range of 1×10-8 mol/L-7×10 -6 mol/L with a detection limit of 5×10 -9 mol/L. The proposed method was successfully applied in the determination of norfloxacin in capsules with satisfactory results.Uniterms: Norfloxacin/determination. Graphene oxide. Nafion.

O sensor voltamétrico utilizado foi fabricado simplismente por cobertura de camada de óxido de grafeno (GO) e filme de Nafion em eletrodo de cabrono vítreo. A vantagem do método proposto foi a resposta eletroquímica sensível para o norfloxacino, atribuída à condutividade elétrica excelente do GO e à função acumulada do Nafion. Sob condições experimentais ótimas, o presente método revelou boa resposta linear para a determinação do norfloxacino na faixa de limite de detecção de 1×10 -8 mol/L-7×10 -6 mol/L. O método proposto foi aplicado com sucesso na determinação de norfloxacino em cápsulas, com resultados satisfatórios.Uniterms: Norfloxacino/determinação. Óxido de grafeno. Nafion.

A novel multiplex fluorescence quenching immune chromatographic strip (FQICS), using quantum dots (QDs) as a fluorescence donor, was proposed to screen sulfonamide (SA) and fluoroquinolone (FQ) residues in chicken samples, simultaneously. The principle of the proposed FQICS is on the basis of the fluorescence quenching effect, and colloidal gold was used as the fluorescence quencher. The limit of detection (LOD) in standard solution was 3 ng mL À1 and 0.6 ng mL À1 for sulfaquinoxaline (SQX) and norfloxacin (NOR), respectively, through visual detection using UV. For specificity analysis, results obtained indicated that this established method could be applied in broad-spectrum detection of SAs and FQs. Then the proposed FQICS was successfully applied in semiquantitative analysis of SQX (30 mg kg À1) and NOR (6 mg kg À1) in spiked chicken samples. The results obtained using the strips showed great agreement with those obtained using an ELISA kit, which indicates the good accuracy of the strips. As a conclusion, the proposed FQICS with a signal "turn-on" mode provides a suitable immunoassay for rapid, sensitive and simultaneous screening of SAs and FQs in chicken samples on-site.
