Dendrimers stabilizing agents

N3P3F6 n(OAr)n and their application as stabilizing agents in LiPFe-contain-ing batteries has been patented. The compound [NP(OMe)2]3 has also been used as stabilizer in lithium-ion batteries.Cyclotriphosphazenes having phenoxy and UV-absorbing groups have been patented. Immobilization of dendrimers based on a cyclotriphosphazene core has been covered. ... 

PAMAM dendrimers can also be used as templating agents and nanoparticle stabilizers for the synthesis of bimetallic particles. The unique ability of dendrimers to host various metal precursors enables the simultaneous complexation of multiple metallic species at its various internal functional groups. The three primary methods of bimetallic nanoparticle synthesis through dendrimer stabilization are partial displacement, co-complexation, and sequential complexation. 

It is worthwhile to point out that dendrimers can also be used as normal capping agents during the synthesis of nanoparticles that do not reside inside the cavities of dendrimers [59,60]. These dendrimer-stabilized nanoparticles, capped with several dendrimer molecules, are usually much bigger than DENs and will not be discussed in this book chapter. 

The main studies on dendrimer-stabilized Cu NPs relate to capping agents derived from just two structures, namely poly(propylene imine) [221, 222] and poly(amido amine) [223, 224]. 

Dendrimers are a special class of arborescent monodisperse nanometer sized molecules that have been used in the synthesis of Au NPs as surface stabilizers or nanoreactor/templates for nanoparticle growth. Moreover, these hybrid nanomaterials have great potential for application in different fields such as sensors, imaging in cells, electrooptical devices, catalysis, drug delivery agents, and so on. 

Furthermore, this lysine dendrimer-bound gadolinium complex exhibits a higher in-vivo stability as a contrast agent and hence a longer residence time in tissue than comparatively simple commercially available gadolinium compounds and thus assures improved visualisation of organs, blood vessels, and tissue (Fig. 8.18) [58],... 

Applications of cationic dendrimers as transport vehicles have been described, with an emphasis on their use as transfection agents for nucleic acids. They can transfect them into a large number of cell lines and primary culture cells.Dendrimers with protonable amine groups can interact with all forms of nucleic acid by electrostatic interactions to form complexes that condense the nucleic acids. Whereas linear polymers often adopt random coil structures, the 3D structure of a dendrimer is characterized by radial symmetry. To solve many cellular obstacles of gene delivery, functionalization and variation of the dendrimer structure is an important tool that can be applied. These systems have shown stability and non-immunogenic properties for their potential use in a high variety of therapeutic applications and have been successfully used as carriers for nucleic acids and drug delivery. ...
