15) An example of the dendritic polymer is the hydroxy-functional Boltorn H60 Dendritic Polymer (from Perstrop).
Miller and his colleagues have made some LEDs out of a different dendritic polymer and are currently preparing to test them.
Boltorn, dendritic polymer polyols as load builders in HR PU foams," Anders Magnusson, Birger Midelf and Bo Haggerman, Perstorp Specialty Chemicals AG; "Free volume determination of polyurethane gels using Positron annihilation technique and the correlation of this volume to physical properties," Victor Sanchez Mendieta, UAEM University, and Suresh N.
However, such differences do not seem to suppress their typical dendritic polymer characteristics (9).
The hybrid system has appropriate biocompatibility and solubility due to the presence of the linear dendritic polymer in physiologic environment, is able to kill cancerous cells due to the presence of doxorubicin anti-cancer drug, is able to quickly pass through the cell walls due to the presence of carbon nanotubes, and can be monitored and directed towards the cancerous tissue due to the presence of iron nanoparticles.
However, actual exploitation of dendritic polymer technology, particularly in more engineering applications, is limited because of difficulties in synthesizing them in large quantities.
Their topics include dendrimer-nanoparticle conjugates in nano-medicine, dendritic polymers for the repair of tissues, the theranostic potential of dendronized iron oxide nanoparticles, structurally flexible and amphiphilic poly(amidoamine) dendrimers as non-viral vectors for siRNA delivery, and the impact of physico-chemical properties on dendrimer pharmacokinetics and biodistribution.
In September 2013, Iranian researchers from Lorestan University succeeded in designing a new type of drug delivery system for anti-cancer drugs by using linear dendritic polymers and iron nanoparticles.
Among the topics are polymer states and properties, cross-linking, bulk and solution processes, small-angle X-ray scattering of polymer systems, and dendritic polymers.
Among their topics are removing endocrine disrupting contaminants from water using macroporous molecularly imprinted selective media, copper ion exchange studies of local (in Turkey) zeolitic tuffs, the impact of calcium on struvite precipitation from anaerobically digested dairy wastewater, the design of microsieves and microsieve processes for suspension fractionation, modifying the surface of polyamide reverse osmosis membranes with hydrophilic dendritic polymers, and Ti02 nanowire free-standing membrane for concurrent filtration and photocatalytic oxidation water treatment.
His research is primarily in the areas of solution rheology combined with light, neutron, and X-ray scattering methods to investigate the physics of complex systems such as biomembranes, polyelectrolytes, associating polymers, gels, polymer crystallization, and dendritic polymers.
