A fluorinated amphiphilic dendrimer based nanosystem to combat PDAC is reported by Juan Liu and co-workers in the article number 20210003.These nanoparticles markedly overcome heterogeneity of drug response resistance primary tumor cells, constituting a promising delivery system for treatment.

In this report we show that composite materials that consist of noble metal nanoparticles stabilized within dendrimer interiors are suitable for use as homogeneous hydrogenation catalysts. These interesting new materials are prepared by sorbing PdII or PtII ions into hydroxyl-terminated poly(amidoamine) (PAMAM) dendrimers (Gn-OH, where Gn represents the nth generation) where they complex with i...

nature nanotechnology | VOL 3 | JANUARY 2008 | www.nature.com/naturenanotechnology 13 that accumulation in each of the organs is determined by size. Although the results show that size matters in biodistribution, it is still unclear why it can markedly affect the way the particles are distributed in vivo. Finally, none of the nanoparticles used in the study appeared to readily cross the blood–b...

This article is an account of the work carried out in the authors' laboratory illustrating the usefulness of dendrimer design for nanoparticle palladium catalysis. The "click" synthesis of dendrimers constructed generation by generation by 1-->3 C connectivity, introduces 1,2,3-triazolyl ligands insides the dendrimers at each generation. Complexation of the ligands by Pd(II) followed by reducti...

15-Membered tri-olefinic azamacrocycles as end-groups of phosphorus-containing dendrimers from generation 1 to 4 are used for obtaining Pt nanoparticles in mild conditions; remarkable and unprecedented branched supramolecular assemblies composed of dendrimers and coalesced Pt nanoparticles are obtained, which become larger for higher dendrimer generations, affording for the first time a very un...

The synthesis and magnetic properties of Ni nanoparticles containing <150 atoms are described. These materials are prepared in an organic solvent using hydrophobic dendrimers as templates, which results in a high degree of size monodispersity. The dendrimer-encapsulated nanoparticles were characterized by UV-vis spectroscopy, transmission electron microscopy, and energy dispersive spectroscopy....

The sol-gel co-condensation of organo-phosphonates to titanium alkoxides enables access to novel organic-inorganic hybrids based on phosphonate-bridged titanium dioxide. In this contribution, we bring new perspectives to the long established sol-gel mineralization of titanium alkoxide species, by harnessing the virtues of the well-designed phosphonate-terminated phosphorus dendrimers as reactiv...

We report that the oxygen binding energy of alloy-core@Pt nanoparticles can be linearly tuned by varying the alloy-core composition. Using this tuning mechanism, we are able to predict optimal compositions for different alloy-core@Pt nanoparticles. Subsequent electrochemical measurements of ORR activities of AuPd@Pt dendrimer-encapsulated nanoparticles (DENs) are in a good agreement with the th...
