Fig. 21. Schematic illustration of phase-transfer catalysis using an amine-terminated den-drimer-encapsulated nanoparticle complexed with a fatty acid (present in the organic phase). The fatty acid surrounds the dendrimer, yielding a monodisperse inverted micelle which is soluble in the organic phase. After catalysis, the catalyst can be reclaimed by changing the pH of the aqueous phase...

Figure 23 shows a biphasic toluene/perfluoro-2-butyltetrahydrofuran (Fluoro-inert FC-75) mixture containing dendrimer-encapsulated Pd nanoparticles complexed with poly(hexafluoropropylene oxide-co-difluoromethylene oxide) monocarboxylic acid prepared via the type of electrostatic modification de-... 

Fig. 23. This photograph shows a two-phase system consisting of (top phase) toluene and (bottom phase) perfluoro-2-butyltetrahydrofuran (Fluoroinert FC-75).The dark color (brown) in the bottom phase indicates that the dendrimer-encapsulated Pd nanoparticles, complexed with poly (hexafluoropropylene oxide-co-difluoromethylene oxide) monocarboxylic acid, are selectively extracted into the fluorous phase. No detectable color was observed in the organic phase. Reprinted with permission from Ref. 103 Copyright 2000 American Chemical Society...

The protein-nanoparticle complex was prepared by adding a dimethylformamide (DMF) solution of preformed CdS nanoparticles ranging from 2 to 4 nm to a solution of heat shock protein. As a result, the CdS nanoparticles diffused into the heat shock pore analogous to a damaged protein over a period of 100 h. TEM analysis revealed that as much as 75% of the proteins contained a single discrete nanoparticle core of CdS. Upon subsequent inclusion, the CdS complex displayed intense photoluminescence from 430 to... 

Another factor that needs to be discussed is BBB penetration. Such an increase could be solved by chemical modification of the reactivator s structure, for example modifications like withdrawal of the quaternary nitrogen or connection of quaternary moiety with lipophilic compounds, which can serve as carriers into the brain (amino acids, steroids, Alzheimer s disease drugs, sugars, etc.), or the use of special carriers (e.g. nanoparticles, complex systems). However, do we really need to increase the oxime level in the...

Figure 8.3 Nanotechnology applications in engineering complex tissues. Cells seeded into biocompatible and nanostructured scaffolds are able to reassemble into functional structures that resemble native tissues under the stimulation of growth factors spatiotemporally delivered by nanoparticles. Complex tissues, like this lobule of tbe liver, could be engineered with the help of devices that are equipped with nanotechnology.
