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.

Importance of the correlation between width and length in the shape analysis of nanorods

Analysis of nanoparticle size through a simple 2D plot enable to extract the correlation between characteristic sizes of nanoparticles. In addition to multivariate analysis, this plot enable to get further insights upon critical steps in NPs growth mechanism.
