The synthesis, characterisation and application of three multifunctional nanomaterials, viz., magnetite-coated gold nanorod (GNR-Fe3O4) hy,brids, gold-coated magnetite (Fe3O4 @Au) nanoparticles and thiolated poly(HEMA-ran-GMA) G4 dendrimer­-CdTe quantum dots (OD-polymer nanocomposites) are reported. These multifunctional nanoparticles which combine two or more nanosystems have enabled significant property enhancement to overcome some of the issues associated with sensing, catalysis and biological applications. In particular, the GNR-Fe3O4 nanohybrids show excellent sensitivity, stability, selectivity and reproducibility for H202 sensing. The self-assembled Fe3O4@Au nanoparticle chains enabled controlling the rate of the A coupling reaction in situ. Novel CdTe QD-polymer nanocomposites were fabricated and characterised, en route to biomedical applications.
