The dependence of the optical properties spherical gold nanoparticles on particle size and wavelength were analyzed theoretically using multipole scattering theory, where complex refractive index was corrected for effect a reduced mean free path conduction electrons in small particles. To compare these theoretical results to experimental data, range 5 100 nm synthesized characterized with TEM UV−vis. Excellent agreement found between theory experiment. It is shown that data produced here can...
A progress report is presented on a selection of scientific, technological and commercial advances in the biomedical applications magnetic nanoparticles since 2003. Particular attention paid to (i) actuation for vitro non-viral transfection tissue engineering vivo drug delivery gene therapy, (ii) recent clinical results hyperthermia treatments brain prostate cancer via direct injection, continuing efforts develop new agents suitable targeted following intravenous injection (iii) developments...
Based on protein folding considerations, a pentapeptide ligand, CALNN, which converts citrate-stabilized gold nanoparticles into extremely stable, water-soluble with some chemical properties analogous to those of proteins, has been designed. These peptide-capped can be freeze-dried and stored as powders that subsequently redissolved yield stable aqueous dispersions. Filtration, size-exclusion chromatography, ion-exchange electrophoresis, centrifugation applied these particles. The effect 58...
A unique, sensitive, and highly specific immunoassay system for antibodies using gold nanoparticles has been developed. The assay is based on the aggregation of that are coated with protein antigens in presence their corresponding antibodies. results an absorption change at 620 nm monitored plate reader. To demonstrate analytical capabilities new technique, monodispersed A-coated particles, averaging 10 diameter, were used to determine level anti-protein serum samples. effects pH,...
Controlled synthesis of multicore magnetic nanoparticles reveals that optimum heating is obtained when the cores are comparatively large and few, minimising core–core interactions inhibit hyperthermia.
The possibility to finely control nanostructured cubic ferrites (MIIFe2O4) paves the way design materials with desired magnetic properties for specific applications. However, strict and complex interrelation among chemical composition, size, polydispersity, shape surface coating renders their correlation not trivial predict. In this context, work aims discuss heating abilities of Zn-substituted cobalt ferrite nanoparticles different zinc contents (ZnxCo1−xFe2O4 0 < x 0.6), specifically...
Dual pH- and thermo-responsive magnetic nanocomposite as a platform for hyperthermia controlled drug delivery in cancer treatment.
Co-precipitation is the most ubiquitous method for forming iron oxide nanoparticles. For a typical co-precipitation synthesis, pH of ferrous and/or ferric ion solution increased via addition base. The latter can be added either slowly (a steady over minutes or hours) fast one-time addition) resulting in an abrupt increase pH. However, understanding mechanism particle formation still lacking, which limits reproducibility reaction due to intermediate phases being present final product. In this...
The scientific community has made great efforts in advancing magnetic hyperthermia for the last two decades after going through a sizeable research lapse from its establishment. All progress various topics ranging nanoparticle synthesis to biocompatibilization and vivo testing have been seeking push forefront towards some new clinical trials. As many, they did not go at expected pace. Today, fruitful international cooperation wisdom gain careful analysis of lessons learned seminal trials...
