Combined far-field, near-field and topographic imaging of nano-engineered polyelectrolyte capsules

Nano-engineered polyelectrolyte capsules (NPCs) were investigated using a multimodal approach based on Confocal Laser Scanning Microscopy, scattering-type Scanning Near-Field Optical Microscopy and Atomic Force Microscopy. Our experiment demonstrates that correlating optical information collected wi...

More Information
Summary:Nano-engineered polyelectrolyte capsules (NPCs) were investigated using a multimodal approach based on Confocal Laser Scanning Microscopy, scattering-type Scanning Near-Field Optical Microscopy and Atomic Force Microscopy. Our experiment demonstrates that correlating optical information collected with far-field and near-field techniques and topographic data collected with scanning probe variants holds significant potential for gaining new insights on the structure of NPCs assembled with layer-by-layer strategies.
