Two-dimensional (2D) nanomaterials are considered a rising star in diverse electrochemical technologies due to their special characteristics. We report here the design and synthesis of 2D titanium carbide/boron nitride nanocomposite via the sonochemical method. The successfully produced TiC/BN nanocomposites were characterized by in-depth electron microscopic and spectroscopic methods and served as an electrocatalyst for the determination of sulfadiazine (SFZ). The good electrocatalytic activity toward SFZ sensing with strong durability and good stability can be achieved by the TiC/BN-modified electrode. The unique structural characteristic of the TiC/BN electrocatalyst is in favor of accommodating more surface sites, improved conductivity, promoted charge-transfer ability, and enhanced surface area. For the proof of the above concept, the TiC/BN-modified electrode was characterized with low charge-transfer resistance (R ct = 20 Ω), good peak potential separation (ΔE p = 0.080 V), and good active surface area (A = 0.106 cm2). According to the measurement results of electrochemical response toward SFZ, the TiC/BN-modified electrode shows a trace-level limit of detection (3.0 nM), a large working range (0.01–44; 59–186 μM), good sensitivity (1.47 μA μM–1 cm2), high selectivity and good reproducibility (4.11%). The proposed electrochemical sensor possesses good detection performance in monitoring human urine samples. The obtained results would shed light on the applications of electrocatalyst in electrochemical sensors.

“…Due to the bifunctional modification, the extraction material is considerably more hydrophilic than conventional PS/DVB polymers and thus easily wettable with water. This polymeric material with a weak ion exchanger provides a wide range of pH stability (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14), protection of the phase from acidic or basic solvents, and its high surface means very high binding capacity (nearly five times higher than silica-based adsorbents). Therefore, the material has a phase which is highly effective for small molecule retention and for hydrophilic layer which is non-adsorptive for proteins.…”

“…Therefore, the extraction material (Chromabond 1 Easy) was obtained from Macherey-Nagel (D€ uren, Germany) and was dry packed in a stainless steel column cartridge (30 Â 4.6 mm id). This material is a polar, bifunctionally modified PS/DVB copolymer with a weak anion exchanger, (specific surface 650-700 m 2 g À1 , particle size 80 mm, pore size 50 Å, pH stability [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Before packing, the empty cartridge was cleaned in an ultrasonic methanol bath.…”

“…Several methods [12][13][14] have been used for the determination of SDZ in a variety of matrices, most of which are based on liquid chromatography [15][16][17][18][19][20][21]. Most of these methods used in biological matrices such as blood and tissues require solid phase extraction (SPE) and several sample preparation processes, like filtration, deproteinisation, extraction, centrifugation and concentration [22].…”

Fast, cheap and simple HPLC methods have been gaining importance in the field of antibiotic residue analysis especially in the context of environmentally friendly and sustainable aquaculture. An effective column-switching technique for HPLC using online extraction column was developed to eliminate the time consuming pretreatment procedures and to facilitate the high throughput analysis of sulfadiazine in fish plasma and muscle as well as in water samples. The standard curves for the determination of sulfadiazine residues from biological matrices and water have good linearity (r 2 > 0.996). The average recovery ranged from 92.2 to 118% with the relative standard deviations of 0.3-9.3%. Limits of detection were determined as 5.7 mg L À1 for water, 8.1 mg L À1 for plasma and 9.6 mg kg À1 for muscle, while limits of quantification were 18.9 mg L À1 for water, 26.9 mg L À1 for plasma and 31.9 mg kg À1 for muscle, respectively. Intra-and inter-day precisions were 0.3-9.3 and 0.4-6.7%, respectively. With the retention time of 12 min and total analysis time less than half an hour, this method provides an effective online extraction process and good sensitivity in liquid chromatography, and can be applied for the determination of residual sulfadiazine in water, fish plasma and muscle at lower than maximum residue level of 100 mg kg À1 fish.

“…In this case, MWCNT and OPy.PF 6 were simply mixed (1:9 w/w), dispersed in DMF, and deposited in a clean GCE, being applied for drug detection in strongly acidic conditions at +0.9 V, presenting a LOD of 0.21 μmol L −1 . The selectivity parameter was tested with ascorbic acid, and since it oxidized at a lower potential (+0.35 V) compared to the sulfadiazine, its interference was eliminated by signal subtraction [ 63 ]. Linear sweep voltammetry (LSV) is another technique employed, however limitedly.…”

The interaction of carbon-based nanomaterials and ionic liquids (ILs) has been thoroughly exploited for diverse electroanalytical solutions since the first report in 2003. This combination, either through covalent or non-covalent functionalization, takes advantage of the unique characteristics inherent to each material, resulting in synergistic effects that are conferred to the electrochemical (bio)sensing system. From one side, carbon nanomaterials offer miniaturization capacity with enhanced electron transfer rates at a reduced cost, whereas from the other side, ILs contribute as ecological dispersing media for the nanostructures, improving conductivity and biocompatibility. The present review focuses on the use of this interesting type of nanocomposites for the development of (bio)sensors specifically for pharmaceutical detection, with emphasis on the analytical (bio)sensing features. The literature search displayed the conjugation of more than 20 different ILs and several carbon nanomaterials (MWCNT, SWCNT, graphene, carbon nanofibers, fullerene, and carbon quantum dots, among others) that were applied for a large set (about 60) of pharmaceutical compounds. This great variability causes a straightforward comparison between sensors to be a challenging task. Undoubtedly, electrochemical sensors based on the conjugation of carbon nanomaterials with ILs can potentially be established as sustainable analytical tools and viable alternatives to more traditional methods, especially concerning in situ environmental analysis.
