The focus of this article is to develop a surface plasmon resonance (SPR) nanosensor to determine chloramphenicol (CAP) using the molecularly imprinted nanoparticles. The CAP imprinted nanoparticles were prepared by miniemulsion polymerization method. Then, the nanoparticles were attached onto the SPR nanosensor surface via temperature-controlled evaporation. Surface characterization studies we...

Anisotropic yolk/shell or Janus inorganic/polystyrene nanocomposites were prepared by combining miniemulsion polymerization and sol-gel reaction. The morphologies of the anisotropic composites were found to be greatly influenced by surface modification of zinc oxide (ZnO) nanoparticle seeds. Two different types of the oleic acid modified ZnO nanoparticles (OA-ZnO) were prepared by post-treatmen...

An original synthetic route, based on the combination of a single-source precursor, UV-photodegradation and inverse w/o miniemulsion, is used to prepare Au nanoparticles (NPs) dispersed on titania. The source of the nanocomposite materials is the photolabile single-source precursor AuCl4(NH4)7[Ti2(O2)2(cit)(Hcit)]2·12H2O, which is suspended in a w/o miniemulsion consisting of different surfacta...

Nanoparticles (NPs) are finding ever-increasing uses in a wide range of fields including photonics, catalysis and medicine, and identification of new compositions and synthetic methods is key to the continued discoveries with these materials. Within the medical arena, NPs are being investigated for drug delivery and medical imaging applications. Our efforts are focused on exploring synthetic pr...

ID No : 113 ABSTRACT A carrier system is efficient if distinct payloads can be selectively released via different stimuli because unwanted and unspecific release can be avoided. For anticorrosion, the wanted carrier system is the one able to release its self-healing agents or corrosion inhibitors upon change of pHor/and redox-potential due to the variation of these two signals at the corroded s...

A simple template-free approach to generate spherical porous anatase nanoparticles by combining the sol-gel process with the inverse miniemulsion technique is reported. These as-synthesized particles of about 200 nm in diameter consist of aggregated small anatase crystallites of several nanometers, thus leading to a high specific surface area of more than 300 m ·g, even after calcination at 400...

Lipids and amphiphilic block copolymers spontaneously self-assemble in water to form a plethora of micelles and vesicles. They are typically fluidic in nature and often mechanically weak for applications such as drug delivery and gene therapeutics. Mechanical properties of polymeric materials could be improved by forming crystalline structures. However, most of the self-assembled micelles and v...
