“…Materials with nanostructures have many specific properties due to their size and space effects; the nanostructured PPy also show practical applications in microelectronics, medical diagnosis, sensing technology, solar cell, and actuators (Kamalzadeh and Shahrokhian 2014;Lu et al 2011;Magdesieva et al 2014;Ramanavicius et al 2010). Different morphologies of PPy have been obtained by changing the synthesis method.…”

The size-controllable polypyrrole (PPy) nanospheres are successfully synthesized by oxidative polymerization of pyrrole using N-methylene phosphonic chitosan (NMPC) as a structure-directing agent. By simply changing the amount of NMPC, the size of the PPy nanospheres can be adjusted from 190 to 50 nm in diameter. The spectrometric results suggest that the electrostatic interactions of phosphate groups in NMPC molecule with pyrrole ring might be a driving force for formation of the uniform and sizecontrollable PPy nanospheres. The PPy nanospheres with the diameter of 100 nm exhibit the largest capacity and a good cycling stability as electrode materials of supercapacitors. The as-prepared PPy nanospheres also can be combined with carbon dots to form composite nanospheres presenting enhanced fluorescence intensity, which show potential application in fluorescence detection.

“…38,41,50–55 However, many of these methods require considerable setup, analysis time and/or high-cost instruments. While the need for direct, and timely selective sensors for atorvastatin, capable of operating in real samples is evident, so far, a very limited number of systems have been described which are based on carbon nanotubes functionalized with polypyrrole films, 44 Fe 3 O 4 -nanoparticles, 42 Au-nanoparticles, 56 graphene, 57 and zinc oxide 58 or by oxidative coupling reactions with Ce( iv )-complexes. 59…”

In the present work, nickel-1,4-benzenedioxyacetic acid was synthesized as a rod-like metal organic material and then modified with alumina nanoparticles to synthesize nickel metal organic modified-Al 2 O 3 nanoparticles. The material was found as an efficient sorbent for the enrichment of atorvastatin in human blood plasma. After the extraction of the sample of plasma by ultrasound-assisted dispersive solid phase extraction, high performance liquid chromatographyultraviolet was used to determine the quantitatively pre-concentrated interest analyte. The conditions for optimum extraction were achieved by the optimization of the volume of eluent, dosage of the sorbent, and time of sonication. Solution pH of 7.0, 250 μL of ethanol, 45 mg of the sorbent, and 10 min of sonication time were the conditions for extracting the atorvastatin maximum recovery of higher than 97.0%. By using desirability function for the optimization of the process, the present method showed a response that was linear ranging from 0.2 to 800 ng/mL with regression coefficient of 0.999 in the plasma of human blood with a satisfactory detection limit of 0.05 ng/mL, while the precision of interday for the current method was found to be <5%. It can be concluded that dispersive solid phase extraction method is effective for the extraction of atorvastatin from human plasma samples (97.4-102%) due to its easy operation, simplicity, repeatability, and reliability.
