Metal—Polyaniline nanocomposites such as Platinum-Polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of Pt+4 ions into Pt nanoparticles. Thepolymerization of aniline was carried out in the presence of 1(2PtCN6 [Potassium Hexa CyanoPlatinate (IV)] as oxidizing agent. During the reaction aniline monomers undergo oxidation andform polyaniline (PANT) w...

Introduction: The present study aimed to evaluate the impact of PbO nano and micro-sized fillers on ordinary and heavy concretes for different photon energies. Material and Methods: The MCNPX Monte Carlo code (version 2.6.0) was used for all simulations in the present study. A model of narrow-beam geometry was validated and utilized to calcul...

Several drugs targeting the pathogenesis of aortic aneurysm have shown efficacy in model systems but not in clinical trials, potentially owing to the lack of targeted drug delivery. Here, we designed a novel drug delivery system using nanoparticles to target the disrupted aortic aneurysm micro-structure. We generated poly(ethylene glycol)-shelled nanoparticles incorporating rapamycin that exhib...

Lipids contain hydrocarbons and are the building blocks of cells. Lipids can naturally form themselves into nano-films and nano-structures, micelles, reverse micelles, and liposomes. Micelles or reverse micelles are monolayer structures, whereas liposomes are bilayer structures. Liposomes have been recognized as carriers for drug delivery. Solid lipid nanoparticles and lipoplex (liposome-polyca...

BACKGROUND It is well documented that Silver Nanoparticles (SNPs) are potent antimicrobial agents. However, little is known about antimicrobial effects of biologically synthesized SNPs at molecular level. In the present study, efficacy of the green microalgae Chlorella vulgaris in biosynthesis of silver nanoparticles and inhibitory effect of the biosynthesized SNPs on growth and virulence of St...

Thermosensitive nanoparticles were prepared via the self-assembly of two different poly(ε-caprolactone)-based block copolymers of poly(N-isopropylacrylamide)-b-poly(ε-caprolactone) (PNPCL) and poly(ethylene glycol)-b-poly(ε-caprolactone) (PEGCL). The self-aggregation and thermosensitive behaviors of the mixed nanoparticles were investigated using 1H-NMR, turbidimetry, differential scanning micr...

Use of metal nanoparticles in biological system has recently been recognised although little is known about their possible effects on plant growth and development. Nanoparticles accumulation, translocation, growth response and stress modulation in plant system is not well understood. Plants exposed to gold and gold nanoparticles have been demonstrated to exhibit both positive and negative effec...

Controllable synthesis of uniform spherical silver nanoparticles was investigated by carrying out a chemical reduction reaction in a micro emulsion, formed under high shear mixing of aqueous silver nitrate solution and 2-ethyl hexanol as organic phase. Sodium borohydride was used as reducing agent and sorbitan monooleate (span-80) as stabilizer. Further, a study has been performed to observe th...

One-dimensional single crystal incorporating functional nanoparticles of other materials could be an interesting platform for various applications. We studied the encapsulation of nanoparticles into single-crystal ZnO nanorods by exploiting the crystal growth of ZnO in aqueous solution. Two types of nanodiamonds with mean diameters of 10 nm and 40 nm, respectively, and polymer nanobeads with si...
