Stimuli responsive polymer/quantum dot hybrid platforms modified at the nanoscale

Fabricating quantum dots polymer hybrid nanostructures, enable realization of many applications, because encaging QDs within polymer matrices enables the control over optical and spectroscopic properties, and introduces a strong resistance to chemical and photo degradation.

The research described in this thesis aims at: synthesis and characterization of CdSe/ZnS core/shell QDs; synthesis and characterization of temperature-responsive polymer matrices; and fabrication of assemblies with potential applications as sensing devices, to be used in bio-nanotechnology.

Furthermore, applications of QDs in bioscience and medicine were reviewed with a special emphasis on the QD cytotoxicity. It is necessary to elucidate the potential adverse effects of these materials, not only for the concerns about the human health and environment protection, but also for the industry to make use of these promising materials in larger scales.
