End-Grafted Polymer Chains onto Inorganic Nano-Objects

Abstract: Organic/inorganic nanohybrid materials have attracted particular scientific and technological interest because they combine the properties of the organic and the inorganic component. Inorganic nanoparticles exhibit interesting electrical, optical, magnetic and/or catalytic properties, which are related with their nano-scale dimensions. However, their high surface-to-volume ratio often induces agglomeration and leads to the loss of their attractive properties. Surface modification of the inorganic nano-objects … Show more

“…The extended open conformation of PSA in PSA-MNPs is most likely due to the higher tendency of the polymer chains to uncoil when anchored to a surface (here a NP surface) at a certain optimized polymer concentration, thereby significantly increasing the number of hydrophilic groups available to attract water molecules [34,[39][40][41]. Thus, the MNPs boost the osmotic properties of PSA by forcing it to assume an open extended configuration.…”

“…for a reversible physisorption of the surfactant, macromolecules, and amphiphilic polymers on the surface of metal oxide nanoparticles and the second one involves the attachment of macromolecular chains onto the nanoparticles surface via chemisorption. [384] In the matter of former approach, a so called "ligand addition" process can be performed wherein the physical interaction between the hydrophobic tails of amphiphilic molecules (e.g., phospholipids) and hydrophobic ligands on the surface of MNPs takes place. [385] In fact, interaction of the long-chain hydrocarbons with hydrophobic surfactants of the core surface leads to liposomal or micellular structures that can interact with water by either ionic interactions or hydrogen bonding due to the hydrophilic heads of surfactants.…”

“…Although such identification is debatable, environmental evaluation of NHs in this category should be pursued with reflection on already existing classical coated-NM studies. The literature on OMCNH involves a wide range of synthesis processes that include: physisorption of organic molecules, [125] electrochemical immobilisation of protein, enzyme or DNA molecules, [44] polymer grafting from or grafting to NM surfaces, [126] emulsification [40] and ionexchange. [127] Such coated NMs are researched in the application areas of nanoelectronics, [125] photovoltaics, [125] chemical and bio-sensing, [128] bio-imaging, [129] controlled drug delivery [130] and cancer therapy.…”
