Hybrid nanoparticles

 

Mixing inorganic nanoparticles or ions and soft matter (liquid crystal, polymer or surfactant) lead to new hybrid systems with combined properties and even synergies useful for material or biomedical applications. We also use up-converting nanoparticles for imaging purposes, photochromic nanomaterials for sensors, photocatalytic nanoparticles for environmental applications.
Two examples of this research are described below:

New colloidal Magnetic Resonance Imaging (MRI) contrast agents

Mixing double-hydrophilic block copolymers containing a poly(acrylic acid) block with gadolinium ions in water leads to the spontaneous formation of polymeric nanoparticles with high magnetic relaxivities that were successfully used for in vivo experiments as MRI contrast agents.

Synthesis of hybrid nanoparticles by flash nano-precipitation

A one step method based on flash nanoprecipitation enables the straightforward synthesis of nanoparticles by decoupling the formation of the inorganic core and surface functionalisation.
