In this study, a simple, portable, unibody semi-flow injection system was coupled with a screen-printed electrode (SFI/SPE) for the on-site electrochemical screening of sibutramine (SBM) in food supplements. The SFI was fabricated by laser engraving acrylic plastic and was attached to a modified SPE with double-sided adhesive tape. The SPE was modified with a nanocomposite of nitrogen-doped graphene nanoflakes and carbon nanotubes synthesized using hydrothermal and ultrasonic methods. The morphological structure and electrochemical properties of the nanocomposite were thoroughly investigated. The portable SFI-SPE sensing system was designed to be interfaced with a smartphone. Sample solutions can be continuously injected into the sensing system using a plastic syringe and SBM is determined by square wave anodic stripping voltammetry, controlled by means of a smartphone. The developed sensing system displayed linear ranges from 0.010 to 10 μg mL⁻¹ and 10-60 μg mL⁻¹ with an LOD of 0.0035 μg mL⁻¹. The sensor delivered a response in a short time and demonstrated not only good reproducibility (RSDs ranging from 2.9 % to 4.9 % (n = 10)) and excellent resistance to interference but also high accuracy. The developed sensor was utilized for the screening and quantification of SBM in food supplements but the system could be used in a wider range of electrochemical (bio) sensor applications in the future.

Fenfluramine, an appetite suppressant used for weight loss, can cause significant harm if overdosed. The unauthorized addition of fenfluramine to slimming foods has raised concerns. Currently, no rapid screening method is available for the quick detection of fenfluramine in the field. This study proposes six new haptens with varying spacer arm lengths and hydrophobicity, promising to elicit antibodies capable of being highly specific and strongly binding to fenfluramine. The study found that highly hydrophobic haptens with long spacer arms favored the generation of highly sensitive antibodies. Key interaction forces for antibody recognition of fenfluramine were revealed by intrinsic molecular mechanisms. Based on the above results, monoclonal antibody for fenfluramine was prepared and an ultrasensitive icELISA method with heterologous coating strategies was developed in slimming foods. The IC₅₀ of the method was 6.25 ng/mL, the linear detection range was 0.47-83.51 ng/mL and the detection limit was 0.10 ng/mL. Recovery rates in tea bags, tablets, capsules, coffee, and beverages ranged from 96.56 % to 108.90 %. The method was successfully applied to blind samples, showing strong correlation with HPLC-MS/MS results. Thus, the developed method is suitable for identifying fenfluramine adulteration in slimming foods.

Application of GC–MS retention index in forensic routine

Author: Ferrari, Ettore Junior ; Lordeiro, Rogerio Araujo ; e Ferreira, Luisa Pereira ; Machado, Yuri

Gas chromatog.-mass spectrometry (GC-MS) is widely used for the identification of substances of forensic interest, but it faces challenges due to the vast diversity of available drugs.In this context, the use of the linear retention index (LRI) can help overcome difficulties associated with the identification of a large number of substances, as it is less susceptible to variations in exptl. conditions compared to retention time (RT).Building an LRI database allows rapid and simultaneous identification of several compounds, including new and structurally similar substances, thus standardizing anal. identification.This study aimed to evaluate the use of the retention index (RI) in both intralab. and interlaboratory forensic routines.Over a 50-wk period on the same GC-MS system, RI values were effectively adjusted by reinjecting an n-alkane mix after maintenance that required vacuum breaks, updating the retention times of each substance evaluated (benzocaine, caffeine, cocaine and flunitrazepam).Interlaboratory reproducibility was evaluated between two forensic laboratories using up to 104 analytes.Two oven temperature programs, three GC brands and two anal. columns were evaluated.Under the same anal. conditions, the ΔRI was ≤10 index units (i.u.) for 103 substances, with testosterone enanthate showing a ΔRI = 11 i.u..The proposed method proved to be reproducible and selective, and the use of RI has demonstrated accuracy as a complementary technique for identifying a wide range of analytes.Furthermore, the sharing of an RI database can strengthen the anal. routine, being a way to quickly obtain information on the identification of new drugs.
