the conducting polymer films have been widely applied in the field of electrochemistry owing to their goodstability, permselectivity, unique physical and chemical properties. a novel nano-au/poly (4-aminobenzoicacid) (paba) film modified carbon paste electrode was fabricated for sensitive detection of acetaminophenin this paper. the paba film and nano-au/paba film were characterized by scanning...

Polymer nanoparticles are vehicles used for delivery of hydrophobic anti-cancer drugs, like doxorubicin, paclitaxel or chemopreventors like quercetin (Q). The present study deals with the synthesis and characterisation of nano formulations (NFs) from Q loaded PLGA (poly lactic-co-glycolic acid) nano particles (NPs) by surface modification. The surface of Q-loaded (NPs) is modified by coating wi...

The reduction of aluminium trichloride by lithium aluminium hydride in the presence of poly(vinylpyrrolidone) or poly(methylmethacrylate) in mesitylene yielded nano aluminium particles in the matrices of respective polymers. Solution phase synthesis methodology was used successfully to produce composites of various Al/polymer ratios. The composites were characterized by powder XRD patterns and ...

We report on the ultrafast photoinduced charge separation processes in varying compositions of poly(3-hexylthiophene) (P3HT) blended with the electron acceptor [6,6]-phenyl-C61-butyric acid methyl ester (PCBM). Through the use of time-resolved terahertz spectroscopy, the time- and frequency-dependent complex photoconductivity is measured for samples with PCBM weight fractions (WPCBM) of 0, 0.2,...

Here, we present the first application of molecular gel-mediated power-conversion enhancement of solar cells, which is based on the excimer emission from a transparent and colourless polymer film that encapsulates a pyrene nano-fibrillar assembly.

The conformation of embedded molecule in a polymer matrix is sensitive to the local nano-environment that the molecule experiences. Particularly, single molecule spectroscopic methods have been utilized to visualize each molecular conformation in local sites of the polymer matrix by monitoring rotational diffusion and fluctuating fluorescence of the molecule. Here, we have performed single mole...

The present work reports the development of pH and enzyme dual responsive polysaccharide vesicular nano-scaffolds for the administration of doxorubicin via physical loading and polymer-drug conjugation to breast cancer cells. Dextran was suitably modified with a renewable resource 3-pentadecyl phenol unit through imine and aliphatic ester chemical linkages that acted as pH and esterase enzyme s...

A nanocomposite containing polypropylene (PP) and nano α-Al2O3 particles was prepared using a Haake internal mixer. Mechanical tests, such as tensile and flexural tests, showed that mechanical properties of the composite were enhanced by addition of nano α-Al2O3 particles and dispersant agent to the polymer. Tensile strength was approximately ∼ 16% higher than pure PP by increasing the nano α-A...

Mesoporous silica nanoparticles (MSNs) were used as a nano-carrier/amplifier to develop a novel MSN-SERS probe for DNA MTase detection. High sensitivity, good selectivity, and rapid analysis are achieved.

background :wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. we investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (hsv-1) in cell culture.   methods : in-vitro c...
