Quantum dots were used as fluorescent probes to investigate nanoparticle penetration into biofilms. The particle penetration behavior was found to be controlled by surface chemical properties.

Here we demonstrate patterning of protein/quantum dot hybrid bionanostructures via electrostatic assembly of engineered negatively charged fluorescent protein with positively charged CdSe/ZnS QD patterns formed through e-beam lithography and post-patterning modification with cationic ligands.
