چکیده
Gold particles are modified with surface-attached bis(beta-cyclodextrin)s bearing S-S bridges to give water-soluble cyclodextrin-modified gold nanoparticles, which are successfully used as recycling extractors for [60]fullerene.

One-pot synthesis of sub-3 nm gold nanoparticle networks connected by thio-based multidentate fullerene adducts.
A new organo-soluble [60]fullerene hexaadduct bearing twelve thiocyanate functions has been synthesized and successfully used as a stabilizing/assembling agent to assemble homogeneous sub-3 nm gold nanoparticles into extended tridimensional networks.
متن کاملSupramolecular aggregates constructed from gold nanoparticles and l-try-CD polypseudorotaxanes as captors for fullerenes.
A series of cyclodextrin-based polypseudorotaxanes (PPRs) were constructed by threading native beta-cyclodextrin or l-tryptophan-modified beta-cyclodextrin onto the amino-terminated PPG chains of different lengths. Subsequently, these PPRs were further assembled to form netlike supramolecular aggregates through the linkage of gold nanoparticles, and the resulting water-soluble Au-PPR aggregates...
متن کاملEvaluation of antioxidant and anti-cancer properties of curcumin / beta- and gamma-cyclodextrin complexes modified with chitosan nanoparticles on lung cancer cell A549
The aim of this study was to investigate the interaction modification of curcumin complex molecule (CUR) in beta- and gamma-cyclodextrin (β-CD and γ-CD) carriers with chitosan (CS) nanoparticles for targeted drug delivery and to compare their performance. The targeted drug delivery system includes the therapeutic agent of the CS nanoparticles targeting section of the same drug and the CD carrie...
متن کاملFullerene-functionalized gold nanoparticles: electrochemical and spectroscopic properties.
Fullerene (C(60))-tethered gold nanoparticles were synthesized by the coupling of the fullerene molecules with peripheral amine moieties on the particle surface. The particle composition was determined by thermogravimetric analysis and FT-IR spectroscopy. The resulting particles exhibited unique optical and electrochemical properties. UV-visible measurements showed that the C(60) characteristic...
متن کاملReversible Phase Transfer of Nanoparticles Based on Photoswitchable Host–Guest Chemistry
An azobenzene-containing surfactant was synthesized for the phase transfer of α-cyclodextrin (α-CD)-capped gold nanoparticles between water and toluene phases by host-guest chemistry. With the use of the photoisomerization of azobenzene, the reversible phase transfer of gold nanoparticles was realized by irradiation with UV and visible light. Furthermore, the phase transfer scheme was applied f...
