In this book, the authors present topical research in the study of dendrimers, with a focus on their synthesis, application and role in nanotechnology. Topics discussed in this compilation include dendrimer-based nanostructured ultralthin films formed by covalent molecular assembly in supercritical carbon dioxide; dendrimer-based host/guest systems for drug delivery; dendrimers for chemotherapeutic drug delivery; dendrimer-templated gold nanoparticles; sorption in liquid crystalline poly (propyleneimine) dendrimers by inverse gas chromatography; dendrimer-based nanocarriers for drug controlled release and targeted delivery; dendrimers as versatile architectures in bio-detection technologies; nanoglobular macrocyclic Gd(III) chelate conjugates as magenetc resonance imaging contrast agents; dendrimers quantum dots nanocomposites for chemical sensing; dendrimers for the functionalisation of textiles; and recyclable metal nanoparticulate catalysts based on dendrimers.
