Case 10391

Novel material with controllable sub-nanometer morphology

Keywords:

Nanotechnology, nanoparticles, surface engineering, ligand shell, molecule orientation, catalysis, water purification, antimicrobials

Applications:

Oil-water separation, chemical catalysis, antimicrobial activity

Problem:

Conveniently synthesizing nanomaterials that present sub-nanometer features on their outside ligand shell to produce unique properties

Technology:

This invention discloses a new family of mixed ligand nanoparticles that show sub-nanometer patterns (e.g. ridges) on their ligand shell. Some of these particles have ridges composed of hydrophilic valleys and hydrophobic peaks. For the first time, there exists the ability to control the supramolecular ordering of the organic ligands on the nanoparticle surfaces, and also to control the surface properties of nanoparticles by varying the mixture of ligands introduced during nanoparticle synthesis. These particles show unique and unexpected solubility, self-assembly and surface chemistry properties.

Advantages:
  • Unique easily controllable properties such as solubility, surface chemistry and reactivity
  • First known materials that exhibit sub-nanometer features
  • Simple synthetic method that can be readily implemented on a large industrial scale
