For the first time, a 3D-printed microfluidic device based on fused deposition modeling was created using poly(lactic acid) as part top of poly(methyl methacrylate) slide, allowing creation transparent channels and used continuous-flow synthesis silver gold nanoparticles. In order to reduce fouling inside microchannels, optimized use segmented flow mineral oil. The synthesized nanoparticles were characterized by UV–Visible spectroscopy scanning transmission electron microscopy. Silver...
Arginine (ARG), ascorbic acid (ASC) and aspartic (ASP) are very popular widely consumed active ingredients used for fatigue treatment or improvement of physical performance. For this reason, these compounds usually available in the same pharmaceutical formulation. In current paper, we describe first-time methods simultaneous determination ARG, ASC ASP using capillary electrophoresis with capacitively coupled contactless conductivity detection (CE-C4D) UV spectrophotometric (CE-UV). The...
The determination of cocaine and common adulterants in seized samples can be used to identify their possible production area traffic routes.
Abstract This study describes the development of a new analytical method for separation and detection cocaine (COC) its adulterants, or cutting agents, using microchip electrophoresis (ME) devices coupled with capacitively contactless conductivity (C 4 D). All experiments were carried out glass commercial ME device containing two pairs integrated sensing electrodes. The running buffer composed 20 mmol/L amino‐2‐(hydroxymethyl) propane‐1,3‐diol 10 3,4‐dimethoxycinnamic acid provided best...
Ammonium and diphenhydramine are active ingredients commonly found in the same pharmaceutical preparations. We report, for first time, a sub-minute method simultaneous determination of ammonium diphenhydramine. The is based on capillary electrophoresis with capacitively coupled contactless conductivity detection. Both analytes can be quantified single run (∼80 injections/h) using 30 mmol/L 2-(N-morpholino)ethanesulfonic acid 15 lithium hydroxide (pH 6.0) as background electrolyte. separation...
This paper presents a simple and low-cost capillary electrophoresis method for ultra-fast simultaneous determination of naphazoline (NPZ) one the following active ingredients: diphenhydramine (DIP), pheniramine (PHEN) or chlorpheniramine (CPHEN).The proposed is based on with capacitively coupled contactless conductivity detection (CE-C 4 D) equipped short length column (10 cm).One sample can be analyzed every 35 s (ca. 100 injections per hour) resolutions between peaks greater than 1.4.The...
Abstract This work presents a single analytical system able to perform high‐throughput determinations of different pharmaceutical molecules on screen‐printed electrodes (SPEs) assembled batch‐injection analysis (BIA) cell. Two types SPEs, both containing carbon conductive ink as working electrode, were selected for the determination levamisole (LVM) in aqueous and sodium levothyroxine (NaLVT) hydroethanolic media. The main characteristics proposed examples are high precision (RSD <3.8 %,...
Pain is the perception of a harmful stimulus on animal organism, which can be mechanical, chemical or thermal.The noxious transduced in electrical impulses by nociceptors, transmitted through sensory fibers to spinal dorsal horn, where nociceptive information modulated and projected supraspinal areas there pain perception.Chronic occurs when acute not treated properly nerve damage result chronic diseases.This type considered debilitating syndrome that impairs quality life patient its...
Serotonin is a neurotransmitter that plays several roles in human health, mainly related to well-being sensation and physiological processes. It metabolite of tryptophan 5-hydroxytryptophan, which are used as dietary supplementation. A simple method was developed separate these three compounds using capillary electrophoresis equipped with capacitively coupled contactless conductivity detection, where the optimized conditions were background electrolyte consisting 3.0 mol L-1 acetic acid...

For the first time, fused deposition modelling (FDM) 3D printing method was used to fabricate a microchip capillary electrophoresis (MCE) with channel dimensions (59 x 65 µm) below 100 μm. Moreover, electrodes conduct capacitively coupled contactless conductivity detection (C 4 D) were integrated into MCE using three conductive thermoplastic filaments containing graphene, carbon black, and copper. After optimizing parameters for multi-material printing, MCE-C D device fabricated in single...
