Surface Modification and Functionalization of Metal and Metal Oxide Nanoparticles by Organic Ligands

Hairy nanoparticle assemblies as one-component functional polymer nanocomposites: opportunities and challenges

“…Metal and metal oxide particles, in particular, have been widely studied and there are multiple chemical modifications that have been shown to work. [89][90][91] For gold and noble metals, possibilities include thiols, [67,[92][93][94] tyrosine and disulfides (which cleave to create a thiolate link), amines, carboxylates, [95] pyridine, and phosphines. These links are relatively weak (and can provide a path for ligand exchange; phosphines and amines can be exchanged for thiols) but can be strengthened by using multiple linkages, either of the same (such as polyphosphines) or different types.…”

Fabrication and Characterisation of Novel Natural <i>Lycopodium clavatum</i> Sporopollenin Microcapsules Loaded <i>In-Situ</i> with Nano-Magnetic Humic Acid-Metal Complexes

“…The paramagnetic iron oxide magnetite nanoparticles have attracted intriguing attentions in several environmental and biomedical applications owing to their biocompatibility [14]- [21]. They were usually surface modified with different functional groups in order to enhance their dispersion stability and affinity to different target species [14] [15] [16].…”

Charge effect of superparamagnetic iron oxide nanoparticles on their surface functionalization by photo-initiated chemical vapour deposition

“…However, none of these reports related the effect of initial surface charge and composition of SPIONs (resulting from the synthesis approach) on functionalization (Neouze and Schubert 2008;Latham and Williams 2008;De Palma et al 2007;Matsuno et al 2004;Georgelin et al 2008). This is significant because surface charge and composition can impact the electrostatic interaction of the SPIONs with the polymer coating.…”
