A sensitive nanosensor for the in situ detection of the cannibal drug
'American Chemical Society (ACS)', 2020Co-Authors: Garrido-garcía, Eva María, Alfonso-navarro María, Díaz De Greñu-puertas, Borja, Marcos Martínez, María Dolores, Costero, Ana M., Gil Grau Salvador, Sancenón Galarza Félix, Martínez-máñez RamónAbstract:[EN] A bio-inspired nanodevice for the selective and sensitive fluorogenic detection of 3,4- methylenedioxypyrovalerone (MDPV), usually known as Cannibal drug, is reported. The sensing nanodevice is based on mesoporous silica nanoparticles (MSNs), loaded with a fluorescent reporter (rhodamine B) and functionalized on their external surface with a Dopamine Derivative (3), which specifically interacts with the recombinant human Dopamine transporter (DAT), capping the pores. In the presence of MDPV, DAT detaches from the MSNs consequently causing rhodamine B release and allowing drug detection. The nanosensor shows a detection limit of 5.2 µM and it is able to detect the MDPV drug both in saliva and blood plasma samples.The authors thank the Spanish Government (projects RTI2018-100910-B-C41 (MCUI/AEI/FEDER, UE) and CTQ2017-87954-P) and the Generalitat Valencia (PROMETEO/2018/024) for support.

synergic effect of pt co nanoparticles and a Dopamine Derivative in a nanostructured electrochemical sensor for simultaneous determination of n acetylcysteine paracetamol and folic acid
Mikrochimica Acta, 2016Co-Authors: Hassan Karimimaleh, Mehdi Hatami, Reza Moradi, Mohammad A Khalilzadeh, Sedighe Amiri, Hasan SadeghifarAbstract:A carbon paste electrode (CPE) was modified with Pt-Co nanoparticles and 2-(3,4-dihydroxyphenethyl)isoindoline-1,3-dione (3,4-DHPID) and then used for determination of N-acetylcysteine (N-AC) in the presence of paracetamol (PC) and folic acid (FA). The Pt-Co nanoparticles were synthesized by the polyol method and characterized by X-ray diffraction, energy dispersive X-ray analysis and transmission electron microscopy. The modified CPE displays good electrocatalytic activity towards the electrooxidation of N-AC in solution of pH 7.0. It was applied to the determination of N-AC in the presence of PC and FA (with well separated signals peaking at 0.2, 0.55 and 0.86 V vs. Ag/AgCl) by using square wave voltammetry. The peak currents are linearly dependent on the concentrations of N-AC, PC and FA in the respective ranges from 0.07 to 500, 1.0 to 850, and 2.0 to 550 μmol·L−1, with detection limits of 0.009, 0.6 and 0.8 μmol·L−1. The modified CPE was applied to the determination of N-AC, PC and FA in (spiked) pharmaceutical and biological samples.

simultaneous determination of n acetylcysteine and acetaminophen by voltammetric method using n 3 4 dihydroxyphenethyl 3 5 dinitrobenzamide modified multiwall carbon nanotubes paste electrode
Sensors and Actuators B-chemical, 2011Co-Authors: Ali A Ensafi, Hassan Karimimaleh, Shadpour Mallakpour, Mehdi HatamiAbstract:Abstract A new Dopamine-Derivative, i.e. N-(3,4-dihydroxyphenethyl)-3,5-dinitrobenzamide (N-DHPB), was synthesized and its application was investigated for the simultaneous determination of N-acetylcysteine (NAC) and acetaminophen (AC) using modified multiwall carbon nanotubes paste electrode. This modified electrode exhibited a potent and persistent electron mediating behavior followed by well separated oxidation peaks of NAC and AC. The peaks current of differential pulse voltammograms of NAC and AC increased linearly with their concentration in the ranges of 0.5–200 μmol L−1 NAC and 15.0–270 μmol L−1 AC. The detection limits for NAC and AC were 0.2 μmol L−1 and 10.0 μmol L−1, respectively. The relative standard deviation for seven successive assays of 1.0 and 30.0 μmol L−1 NAC and AC were 1.7% and 2.2%, respectively. The proposed sensor was successfully applied for the determination of NAC in human urine, tablet, and serum samples.

biomimetic Dopamine Derivative for selective polymer modification of halloysite nanotube lumen
Journal of the American Chemical Society, 2012Co-Authors: Weng On Yah, Yuri Lvov, Hiroe Soejima, Atsushi TakaharaAbstract:We demonstrate the use of a catecholic anchor (Dopa) for selective modification of the inner surface of an halloysite clay nanotube. Aqueous Dopa binds to alumina at the tube lumen and does not bind the silica surface under the same conditions. Selectivity of surface modification was evidenced using X-ray photoelectron spectroscopy (XPS) and 13C solid state NMR spectroscopy. Surface-initiated atom transfer radical polymerization (SI-ATRP) was performed through selectively adsorbed Dopa to graft a layer of polymer brush into the nanotube lumen.

jacket free stir bar sorptive extraction with bio inspired polyDopamine functionalized immobilization of cross linked polymer on stainless steel wire
Journal of Chromatography A, 2015Co-Authors: Zixi Zhang, Wenpeng Zhang, Zili CheAbstract:Abstract Stainless steel wire (SSW) is a good substrate for stir bar sorptive extraction (SBSE). However, it is still a challenge to immobilize commonly used cross-linked polymers onto SSW. In this work, we present a new approach for immobilization of the cross-linked organic polymer onto SSW for jacket-free SBSE. A Dopamine Derivative was firstly synthesized; by introducing a mussel-inspired polyDopamine process, a stable coating layer was finally generated on the surface of SSW. Secondly, the cross-linked polymer was synthesized on the polyDopamine-modified SSW by using acetonitrile as the porogen, acrylamide (AA) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as the cross-linker and 2,2′-azobis (2-methylpropionitrile) as the initiator. A diluted pre-polymerization solution was carefully prepared to generate a thin layer of the polymer. The prepared poly(EGDMA-AA)-modified stir bar showed high stability and good tolerance toward stirring, ultrasonication, organic solvents, and strong acidic and basic conditions. Morphology and structure characterization of coatings were performed by scanning electron microscopy and Fourier transform infrared spectra, respectively. The prepared poly(EGDMA-AA)-modified stir bar showed great extraction efficiency toward protoberberines, with enrichment factors of 19–42. An SBSE-HPLC method was also developed for quantitative analysis of protoberberines. The method showed low limits of detection (0.06–0.15 ng mL−1), wide linear range (0.5–400 ng mL−1), good linearity (R ≥ 0.9980) and good reproducibility (RSD ≤ 3.60% for intra-day, RSD ≤ 4.73% for inter-day). The developed method has been successfully applied to determine protoberberines in herb and rat plasma samples, with recoveries of 88.53–114.61%.

A sensitive nanosensor for the in situ detection of the cannibal drug
'American Chemical Society (ACS)', 2020Co-Authors: Garrido-garcía, Eva María, Alfonso-navarro María, Díaz De Greñu-puertas, Borja, Marcos Martínez, María Dolores, Costero, Ana M., Gil Grau Salvador, Sancenón Galarza Félix, Martínez-máñez RamónAbstract:[EN] A bio-inspired nanodevice for the selective and sensitive fluorogenic detection of 3,4- methylenedioxypyrovalerone (MDPV), usually known as Cannibal drug, is reported. The sensing nanodevice is based on mesoporous silica nanoparticles (MSNs), loaded with a fluorescent reporter (rhodamine B) and functionalized on their external surface with a Dopamine Derivative (3), which specifically interacts with the recombinant human Dopamine transporter (DAT), capping the pores. In the presence of MDPV, DAT detaches from the MSNs consequently causing rhodamine B release and allowing drug detection.
