Multifunctional shape and size specific magneto-polymer composite particles.
Interest in uniform multifunctional magnetic particles is driven by potential applications in biomedical and materials science. Here we demonstrate the fabrication of highly tailored nanoscale and microscale magneto-polymer composite particles using a template based approach. Regiospecific surface functionalization of the particles was performed by chemical grafting and evaporative Pt depositio...
متن کاملSynthesis and Characterization of Spherical Magnetite/Biodegradable Polymer Composite Particles.
A method for preparing colloidal particles formed by a magnetite nucleus and a biodegradable poly(DL-lactide) polymer coating is first described. The method is based on the so-called double-emulsion technique, employed to obtain polymeric spheres loaded with therapeutic drugs, to be used as drug delivery vectors. The aim of this work was to obtain, in a reproducible and rather simple way, collo...
متن کاملMECHANICAL PROPERTIES OF DENTAL COMPOSITE MATERIALS REINFORCED WITH MICRO AND NANO-SIZE Al2O3 FILLER PARTICLES
Abstract: Composite specimens were prepared by dispersion of various amounts of nano-sized Al2O3 fillers in a monomer system containing 60% Bis-GMA and 40% TEGDMA. For comparative purposes, composite samples containing micrometer size Al2O3 fillers were also prepared following the same procedure. The mechanical properties of the light- cured samples were assessed by three-point flexural strengt...
متن کاملSwelling behavior of nanoscale , shape - and size - specific , hydrogel particles fabricated using imprint lithography †
Recently a number of hydrogel-based microand nanoscale drug carriers have been reported including top down fabricated, highly monodisperse nanoparticles of specific sizes and shapes. One critical question on such approaches is whether in vivo swelling of the nanoparticles could considerably alter their geometry to a point where the potential benefit of controlling size or shape could not be rea...
متن کاملOn the Size and Shape of Polymers and Polymer Complexes
Preface The central issue in this thesis is the detailed investigation of size and shape of polymers and polymer aggregates. A large part of the work is concerned with computational studies of grafted polymers under confinement (Paper I-III), with the aim of a better understanding of the behaviour of chains with varying interaction potential and stiffness. The results can then serve as a test f...
