in this work, a new, simple and fast method for the solid phase extraction-spectrophotometric determination of phosphate using cetyltrimethyl ammonium bromide immobilized on alumina-coated magnetite nanoparticles (ctab@acmnps) has been developed. the determination of phosphate is based on the molybdenum blue method which was monitored at λmax of 810 nm. mnps and acmnps characterized by sem, vsm...
this paper presents a comparison between variational iteration method (vim) and modfied variational iteration method (mvim) for approximate solution a system of volterra integral equation of the first kind. we convert a system of volterra integral equations to a system of volterra integro-di®erential equations that use vim and mvim to approximate solution of this system and hence obtain an appr...
Poor ocular bioavailability of drugs (<1%) from conventional eye drops (i.e., solution, suspension, and ointments) is mainly due to the physiologic barriers of the eye. In general, ocular efficacy is closely related to ocular drug bioavailability, which may be enhanced by increasing corneal drug penetration and prolonging precorneal drug residence time. In our current work, we developed a collo...
To facilitate the administration of combined 5-Fluorouracil (5-FU) and gold nanoparticles (for photothermal treatment purposes), we developed 5-FU-gold-poly(lactide-co-glycolic acid) (5-FU-Au-PLGA) nanovehicles, via the nanoprecipitation method. The gold nanoparticles were incorporated inside the 5-FU-PLGA carriers using a roller mixer. Morphological analysis using atomic force microscopy (AFM)...
Nanoprecipitation of miglyol into droplets surrounded by a functional glycopolymer generates nanocapsules of biointerest. Fluorophores are trapped in situ or post-grafted onto the crosslinked polymer shell for efficient imaging. The resulting colloids induce aggregation of bacteria through strong specific interactions and promote their facile removal.
