Dendrimers in Nanoscale Confinement: The Interplay between Conformational Change and Nanopore Entrance

“…Hence, it is not clear to which degree the structural flexibility of differently sized dendrimers influences their entrance into pores; their rigidity usually increases with bigger diameter. 1 Furthermore, there is no detailed information on the mechanism for pore insertion, that is, whether the dendrimers insert completely or partly into a pore. Finally, it is not known whether the nanoscale confinement of dendrimers has an effect on the charge state of the ionizable functional groups of the molecules.…”

Metallodendrimers in three oxidation states with electronically interacting metals and stabilization of size-selected gold nanoparticles

“…T o date, dendrimers and metal nanoparticles (NPs) have been largely involved in materials science including nanomedicine, photonics and supramolecular chemistry [1][2][3][4][5] , and in particular metallodendrimers and dendrimercontaining NPs 2-4,6-11 have been efficiently designed for catalysis [2][3][4] , photophysics [7][8][9][10][11] and sensing [9][10][11][12][13] . Redox-stable metallodendrimers are a specific class of materials allowing redox anion recognition, sensing [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and biosensing 14,15 that have been used essentially with ferrocene derivatives [12][13][14][15] .…”

Although biferrocene-and silicon-bridged biferrocene-terminated dendrimers are known 5,[14][15][16] , no dendrimers have yet been isolated in several oxidation states owing to instability of the oddelectron species.…”

Nitric oxide releasing-dendrimers: an overview

“…Dendrimers are molecules of the dendritic materials group, which is also composed by dendronized and hyperbranched polymers, dendrons and dandrigrafts (Carlmark et al, 2009;Astruc, Boisselier, Ornelas, 2010). The main difference between dendrimers and dendrons regarding to the other dendritic polymers is related to their shape: dendrimers and dendrons are perfectly branched (Figure 2).…”

“…One of the key features related to dendrimers is the possibility of tailoring its surface through chemical modifications, and their conjugation with molecules or ions of interest (Astruc, Boisselier, Ornelas, 2010;Archut et al, 1998;Vögtle et al, 1999). Major applications are related to the drug delivery systems development (Gillies, Fréchet, 2005;Medina, El-Sayed, 2009;Nanjwade et al, 2009;Wijagkanalan, Kawakami, Hashida, 2011;, solubility (Devarakonda, Hill, Villiers, 2004) and biocompatibility improvements (reduce toxicity) (Duncan, Izzo, 2005;Sadekar, Ghandehari, 2010;Ciolkowski et al, 2012), magnetic resonance image (MRI) contrast (Wiener et al, 1994;Margerum et al, 1997;Kobayashi et al, 2003;Kojima et al, 2011;Tang et al, 2012), targeted drug delivery (Yang et al, 2009;Menjoge et al, 2011) and gene delivery (Dufès, Uchegbu, Schätzlein, 2005;Kim et al, 2007;Mintzer, Simanek, 2009;Shcharbin, Klajnert, Bryszewska, 2009;Nam et al, 2012).…”
