Dermal drug delivery is highly preferred by patients due to its several advantages. Protein therapeutics have attracted huge attention recently. Since dermal delivery of proteins encounter problems, in this investigation, zinc oxide nanoparticles and calcium phosphate nanoparticles were compared as enhancers for dermal permeation of albumin. Albumin was applied simultaneously with zinc oxide na...

In this study, an asymmetric supercapacitor (ASSC) device is assembled by the deposition and annealing of silver-doped mixed metal oxides on reduced graphene oxide (rGO)/Ni foam activated carbon (AC) Ni as positive negative electrodes, respectively. The best performing Ag:MnCoNiO active material synthesized rGO/Ni using chronopotentiometry combined with heat treatment. XRD study clearly confirm...

in this research nickel zinc ferrite nanoparticles with composition of ni1-xznxfe2o4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °c for 5 hours. the structure of nanoparticles was studied using x-ray diffraction pattern. the lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticles depend on zinc concentration. the crystal...

BACKGROUND Gold nanoparticles are useful tools for biological applications due to their attractive physical and chemical properties. Their applications can be further expanded when they are functionalized with biological molecules. The biological molecules not only provide the interfaces for interactions between nanoparticles and biological environment, but also contribute their biological func...

Nobel metal nanoparticles have drawn significant attention for a wide range of new applications in various fields including biology and medicine. Research work during the last two decades have clearly demonstrated that the properties of nanoparticles, in particular silver nanoparticles are strongly influenced by shape, size and size distribution, which is dictated by the synthetic method adopte...

in present study we studied using green routes for microwave assisted synthesis of alumina nanoparticles from aluminum nitrate. it was revealed that when plant extracts are used, no specific stabilizer is needed. structural characterization of nanoparticles was studied using x-ray diffraction that showed semi-crystalline structure for two of plant extracts, other xrd patterns had no significant...

In this brief review, gold nanoparticles conjugated with functional polymers are described from the viewpoint of application to sensing materials. The optical properties of gold nanoparticles, the synthesis of polymer-functionalized gold nanoparticles, and their analytical applications are discussed. Polymer-functionalized gold nanoparticles are categorized into two classes: biopolymer-conjugat...

results the results revealed the formation of spherical silver nanoparticles with an average size of 10 nm. moreover, concentration of snps in a 25 ml sample containing both snps and plant extract biomass was 2.934 mg/l on average. serial microdilution test showed that snps at the concentration of 50 μg/ml can inhibit growth of the pathogen. conclusions the present study extends the existing li...
