Controllable Gold Nanocluster–Emulsion Interface for Direct Cell Penetration and Photothermal Killing

Abstract: In the view of their ability to be uptaken by cells, colloidal particles can exert diverse physiological effects and are promising vehicles for the intracellular delivery of biologically active substances. Given that the modulation of biomaterial interfaces greatly facilitates the prediction and control of the corresponding cellular responses, the interfacial behavior of hydrophobic dye‐modified gold (Au) nanoclusters (Au NCs) is rationally designed to develop Au NC‐containing emulsions and control their bioin… Show more

“…40 Moreover, the ultra-small size (B2 nm) may permit the doping of Au NCs with good dispersion and without interference to the intrinsic structure of the artificial substrate. 41,42 Meanwhile, with the selected biomolecules as organic ligands, Au NCs can assemble with the artificial substrate noncovalently, readily avoiding complex chemical links. [43][44][45] Therefore, customized Au NCs with good biocompatibility show promising potential in the smart release of bioactive substances.…”

“…Nanomaterials can be easily engineered with different intrinsic physical and surface chemical properties. Silver nanomaterials have generally been synthesized by the reduction of Ag­(I) to Ag(0) and then or spontaneously stabilized by surface agents . Proteins containing reductive and coordinative amino acids, such as cysteine, glutamine, and tyrosine, can be used as both reductants and stabilizers in the preparation of nanomaterials. By precisely controlling the reaction conditions, silver nanoparticles and even atomically precise silver nanoclusters can be obtained. Compared to nanoparticles, silver nanoclusters consist of a defined number of silver atoms and organic ligands, which featured a quasimolecular structure.…”
