Abstract During the last decade, progress has been made in on‐site detection of abused drug use. Herein, we present an electrochemical biosensor for one synthetic cannabinoids (SCs), JWH‐073, using poly (methyl methacrylate) (PMMA) hyperbranched copolymer (HBC) as a base coating and antibody molecules to bind JWH‐073 surface. Modification surface is proved with various techniques such differential pulse voltammetry, cyclic impedance spectrometry. The limit linearity (in logarithmic scale)...
Pesticides are harmful compounds even in trace levels for human health, so the importance of determination these is increasing day by day. Magnetite-molecularly imprinted polymer and high resolution liquid chromatography has been combined preconcentration sensitive selective pirimicarb. The developed method appeared to be rapid since total procedure detection pirimicarb can completed within one hour. magnetic reusable same used at least ten cycles Limit (LOD) was found 1.60 µg L−1 linear...
Biopolymers such as alginate and gelatin have attracted much attention because of their exceptional adsorption properties biocompatibility. The magnetic hydrogel beads produced used in this study had a core structure composed magnetite nanoparticles shell alginate. combination the metal-ion binding ability mechanical strength presents new approach for removal metal from water sources. were designed aluminum fully characterized using various methods, including Fourier transform infrared...
Abstract Stabilization of biomolecules on matrices is critically important. Here we constructed composite nanofibers with magnetic features by electro‐spinning nanoparticles (MNP) in an appropriate polymer matrix a collector surface for multiple uses. ‘Poly(vinylalcohol)‐polyethyleneimine/Fe 3 O 4 nanoparticles’ (PVA‐PEI/MNP) nanofiber was used the screen printed electrodes (SPE) to serve as platform glucose oxidase (GOx) biofilm model biomolecule. To show potential application this material...
A sensitive and selective method based on the determination of haloperidol with usage magnetite‐molecularly imprinted polymer high‐resolution liquid chromatography has been developed. This novel is rapid as detection procedure for can be completed within a total time 1 h. The same used at least 20 times. proposed succesfully applied to synthetic urine serum samples recoveries spiked were in range 94.7–100.7%. limit quantification 2.25 7.50 μg/L, respectively. Linearity calibration graph was...
A new nickel/nickel boride-based nanosorbent which provides high sorption efficiency for tin(IV) was developed in this study. The sorbent capacity found to be 26.33 ± 2.18 mg tin(IV)/g (n = 3). Tin(IV) can determined by measuring the fluorescence signal of tin(IV)–flavonol complex. Recovery with 1 mol/L hydrochloric acid 98.70 1.29 5). limit detection and quantification method were 0.5 1.7 µg/L, respectively. calibration graph linear range 4–80 µg/L. adsorption type using isotherms....
In this paper, magnetic-molecularly imprinted polymer was used for the preconcentration of trace levels imidacloprid in water and apple samples prior to liquid chromatography-quadrupole-time-of-flight mass spectrometric determination. The selectivity magnetic united with sensitivity high resolving power chromatographic system. developed method showed a linear range from 10.0 500.0 µg/L. quantitative recoveries were obtained 92.0%-99.0 %. relative standard deviations intra-day inter-day tests...
Abstract A new type polymeric adsorbent, poly(allylphenol‐ co ‐hydroxyethyl methacrylate‐ ‐vinyl imidazole) (PAHV), is synthesized in this study. 2‐Hydroxyethyl methacrylate used as complementary monomers along with 1‐vinyl imidazole and allylphenol monomers. The photopolymerization method preferred a synthesis benzophenone the photoinitiator. effectiveness of PAHV against bacterial species such Escherichia coli Staphylococcus aureus investigated by Clinical Laboratory Standards Institute...
The adsorption behavior of aluminium ions on chamotte clay has been studied in this study. Chamotte used for the first time determination trace levels aqueous solutions. Quantitative and recovery were both rapid reached an equilibrium 30 minutes. Aluminium was detected based formation highly fluorescent Al(III)-morin complex. Two linear calibration graphs obtained range 0.5-10 µg L-1 10-100 with detection limits 0.12 1.12 L-1, respectively. characterized by scanning electron microscope...
