Abstract Herein, we present and discuss the development of a novel sensor for aflatoxin B2 (AFB2) determination by two methods of functionalization. The first method was performed, by the electrodeposition of zinc oxide nanoparticles (ZnO-NPs), coated with a mixture of chitosan (CS) and AFB2 on the gold-working area of a screen-printed electrode. As for the second functionalization method, it was carried out by electropolymerization of pyrrole (Py) and AFB2 to form polypyrrole/AFB2 (PPy/AFB2) on...

Abstract The toxicological and environmental damage caused by glyphosate [N-(phosphonomethyl) glycine] (GLY) has been well documented, however, limited efforts have been made to detect it in the environment. In response to that, we report the development of an extremely sensitive electrochemical sensor for GLY detection in water. This novel concept of glyphosate sensor is based on molecularly imprinted polymer (MIPs) made of chitosan (CS) biopolymer electrochemically deposited onto a gold microe...

Abstract Tetracycline (TC) is a veterinary drug, wildly prescribed for prophylactic and therapeutic purposes. Consequently, its remaining residues in food products have to be regularized. We report in this paper about the development of a novel immunosensor based on an integrated bio micro-electromechanical system (Bio-MEMS) containing eight gold microelectrodes (µWEs), an integrated silver and platinum reference and counter electrodes, respectively. TC immobilization on the µWEs surface was con...

Abstract A simple and highly sensitive approach was performed to synthesize a selective sulfaguanidine (SG) sensor based on a molecularly imprinted electropolymer of acrylamide (PAM) for honey quality control. SG was detected by measurements of electrochemical impedance spectroscopy (EIS) and differential pulse voltammetry (DPV). These techniques were applied successfully to determine SG with an excellent selectivity when compared to the results of interfering compounds. Furthermore, unprecedent...

Abstract Moroccan and French honeys from different geographical areas were classified and characterized by applying a voltammetric electronic tongue (VE-tongue) coupled to analytical methods. The studied parameters include color intensity, free lactonic and total acidity, proteins, phenols, hydroxymethylfurfural content (HMF), sucrose, reducing and total sugars. The geographical classification of different honeys was developed through three-pattern recognition techniques: principal component ana...

Abstract Sulfapyridine (SPy) is a sulfonamide antibiotic largely employed as veterinary drugs for prophylactic and therapeutic purposes. Therefore, its spread in the food products has to be restricted. Herein, we report the synthesis and characterization of a novel electrochemical biosensor based on gold microelectrodes modified with a new structure of magnetic nanoparticles (MNPs) coated with poly(pyrrole-co-pyrrole-2-carboxylic acid) (Py/Py-COOH) for high efficient detection of SPy. This analy...

Abstract Sulfapyridine (SPy) as a category of sulfonamides, have been widely used as veterinary drugs for prophylactic and therapeutic purposes. However, several classes of bacteria have become resistant to this drugs due to their abusive uses. This practice can also signify a potential risk to human health since many diseases may emerge, such as thyroid cancer and anaphylactic reactions. We report in the present work the development of a highly sensitive Biomicro-electro-mechanical systems (Bio...

Main possible honey fraud is the addition of various sugar syrups. But, there are also other types of fraud, such as deception on the geographical and/or botanical origin product. Providing a product of the hive with full authenticity is therefore crucial for the preservation of beekeeping. In this pursuit, voltammetric electronic tongue (VE-tongue) was employed to classify honey samples from different geographical and botanical origins. Furthermore, VE-tongue was used to detect adulterants such...
