1 - An Investigation of the Charge Effects on the Uptake and Release Capacity of Mesoporous Silica Nanoparticles as Vehicles for Short Oligonucleotides

All of the samples (denoted as PEI-MSN, M-MSN, PEI-M-MSN, and PEG-PEI-MSN, where, M= Fe2+, Fe3+, Co2+, Zn2+, Al3+), were unambiguously characterized by conventional techniques including FTIR, XRD, SEM, and BET. The adsorption capacity of siRNA was found to be more related to the zeta potential of the samples than their specific surface areas. The best adsorption result was obtained by using PEI-Fe(III)-MSN (48.8 µg of siRNA per mg of support). The release of siRNA from PEIFe(III)-MSN, was also good (91.5%), but a burst release profile was observed. Interestingly, when a layer of PEG was used as a co-modifier, a sustained release profile was achieved, and meanwhile, the released amount of siRNA was improved (93.2%). The whole combination showed noconsiderable cytotoxicity according to the MTT test. Manuscript profile -

Mimicking the natural receptors of DUL drug by synthesizing its MIP would lead to formation of some special active sites, which make able the MIP to accept only this special medicinal compound. Therefore, this MIP, which has been templated by DUL, could selectively absorb the molecules of DUL from the mediums in certain conditions and could release those chemical species in another place with different conditions. This MIP with its artificial receptors could be applied as a carrier for drug delivery applications and sustained released tablets. In order to synthesize this MIP based carrier, the precipitation polymerization method was applied. Also, methacrylic acid (MAA; as the functional monomer), 2,2-azobisissobutyronitrile (AIBN; as the initiator), and ethylene glycol dimethacrylate (EGDMA;as the cross-linker), were applied to obtain this sorbent. Moreover, the release kinetics of the drug was investigated by HPLC system, which was shown to be fitted with the Higuchi expressionpattern at least at 5.8, and 6.8 pHs. Finally, the results revealed that the synthesized MIP is able to be used in formulation of the sustained released tablets. Manuscript profile -

3 - Fabrication of Graphene Oxide Nanocomposite Based on Poly(3-hydroxybutyrate)-Chitosan as a Useful Drug Carrier

The obtained nanocomposite was designated as GO/PHB-CS-gP(MMA-b-(PEGMA-ran-DMAEMA)) and investigated as a drug delivery system. The synthesized products were characterized by FTIR, 1HNMR, scanning electron microscopy (SEM), dynamic light scattering (DLS) and thermogravimetric analysis (TGA). Doxorubicin (DOX) as an anticancer drug was loaded on the synthesized GO nanocomposite and the drug encapsulation efficiency was calculated about 76.4%. The release profiles indicated that the resulting GO nanocomposite has a pH-responsive behavior under physiological conditions due to the hydrogen bonding interaction between PHB-CS-g-P(MMA-b-(PEGMA-ran-DMAEMA)) and GO. The release property of DOX from GO nanocomposite exhibited a slow sustained release, and suggested that the GO/PHB-CS-gP(MMA-b-(PEGMA-ran-DMAEMA)) nanocomposite could be an appropriate candidate as a useful nanocarrier for the release of DOX in controlled drug delivery systems for treatment of cancer cells.

We used sulfanilamide as a complexing agent to form a hydrophobic complex with Pb2+, and a mixture of choline chloride-phenol as an extraction solvent. We investigated and optimized several parameters affecting the analyte's extraction recovery, including pH of the sample solution, concentration of the complexing agent, mole ratio of choline chloride phenol, volume of extraction solvent, volume of tetrahydrophoran (as an aprotic solvent), and ultrasonic time. Under the optimized conditions, we found that the proposed method has a linear range of 0.5-10 µg L-1 Pb2+ and a limit of detection of 0.16 µg L-1 Pb2+ (n=6). The proposed method's accuracy was verified using certified reference material-trace metals in drinking water (CRM-TMDW) samples. We also successfully used the proposed method to determine trace levels of Pb2+ in different water samples. In conclusion, our study offers an effective UA-LPMEbased method for preconcentrating trace levels of Pb2+ that can be applied to environmental monitoring and analysis. Manuscript profile -

For the adsorption characterization of the adsorbent used in benzyl paraben adsorption, BET, FTIR, XRD, and SEM analyses were performed. The impacts of variables including initial benzyl paraben concentration (X1), pH (X2), adsorbent dosage (X3), and sonication time (X4) came under scrutiny using response surface methodology (RSM). The values of 10 mg L-1, 0.03 g, 7.0, and 4.0 min were considered as the ideal values for benzyl paraben concentration, adsorbent, pH, and contact time, respectively. Adsorption equilibrium and kinetic data were fitted with the Langmuir monolayer isotherm model and pseudo-second-order kinetics (R2: 0.999) with maximum adsorption capacity (92.0 mgg-1), respectively. The predicted values were in agreement with experimental values obtained for the components of the mixture. The values at the optimized process conditions indicated a commercially viable route for optimal removal of dyes from wastewater. Manuscript profile -

Ag NPs/ Ziziphus jujuba kernelas an effective catalyst was prepared through reduction of Ag+ions using Tilia platyphyllos extractas the reducing and capping agent and Ag NPs immobilization on Ziziphus jujuba kernel surface in the absence of any stabilizer or surfactant. According to FT-IR analysis, the hydroxyl groups of phenolics in Tilia platyphyllos extract as bioreductant agents are directly responsible for the reduction of Ag+ions and formation of Ag NPs. The as-prepared catalyst was characterized by Fourier transform infrared (FT-IR) and UV-Vis spectroscopy, field emission scanning electron microscopy (FESEM) equipped with an energy dispersive X-ray spectroscopy (EDS), Elemental mapping, X-ray diffraction analysis (XRD) and transmittance electron microscopy (TEM). The synthesized catalyst was used in the reduction of Congo Red (CR), and Methyl Orange (MO) at room temperature.The Ag NPs/Ziziphus jujuba kernel showed excellent catalytic activity in the reduction of these organic dyes. In addition, it was found that Ag NPs/Ziziphus jujuba kernelcan be recovered and reused several times without significant loss of catalytic activity. Manuscript profile -

In order to monitor the trough level of the drug, sensitive analytical methods are in demand.Therefore, for detection of trace levels of this drug, the trend solvent bar microextraction method coupled with HPLC-UV were implemented. Application of pH gradient of 10.3 and 3.0 (donor and acceptor phase, respectively) enabled preconcentration and microextraction of the target analyte. The results were modeled using Artificial Neural Network (ANN) successfully.The optimum results were obtained with a stirring rate of 365 rpm and salt addition by 15.1% at 25°C after 26 min. The limit of detection and quantification were 7.0 ng mL-1and 20 ng mL-1, respectively. It offered good linearity range of 20-5000 ng mL-1 with a coefficient of estimation higher than 0.9972 and a preconcentration factor of 112. The relative standard deviations of analysis were 4.6% within a day (n=3) and 6.2% between days (n=9).Overall, this method can be employed for several purposes such as for dosage adjustment in ADHD patients, clean validation in the pharmaceutical industry, and for trace determination in forensics.

Therefore, development of simple and rapid methods for simultaneous determination of them in routine analysis has a great significance for many researchers. Therefore, for the first time, nanocomposite of graphene (Gr)LaMnO3has been utilized to fabricate the new electro-chemical sensor for simultaneously determining DA and UA via immobilizing Gr-LaMnO3 on the glassy carbon electrode(GCE). Because of the very god catalytic activities, greater electrical conductivity as well as higher surface area of the Gr-LaMnO3, DA and UA with two clearly described peaks have been simultaneously determined at the Gr-LaMnO3 modified electrode. Relative to peaks at the bare GCE, oxidation currents of DA and UA notably enhanced. Moreover, the catalytic peak current linearly depended on concentration of DA and UA in a range of 0.33 – 283.3 and 0.33 –283.3 μM with 0.040 and 0.051 μAμM-1sensitivity. In addition, limit of detection (LOD) for DA and UA equaled 0.03 and 0.045 μM and diffusion coefficient for DA and UA diffusion at the modified electrode has been computed as 1.71×10−5 and 1.38×10−5 cm2s−1, respectively. It has been found that our electrode could have a successful application for detecting DA and UA in real samples. Thus, this condition demonstrated that the Gr-LaMnO3 nanocomposite displays good analytical performances to detect DA and UA. Manuscript profile -
