Excellent performance of dendrimer-based magnetic nanoparticles in the heavy metal recycling. The dendrimer combined with magnetic nanoparticles has integrated both their advantages,can prepare efficient adsorbent for heavy metal ions, and achieve the analytical recovery of heavy metal ions without membrane material. Dendrimer can be recycled 10 times. Dendrimer modified magnetic nanoparticles has good dispersion with uniform particle size. Metal ion removal rate of the magnetic nanoparticles is about 30%, while the dendritic polymer-modified magnetic metal particles have better adsorption capacity up to 80%, which is 2.5 times more than unmodified one. pH affects adsorption of heavy metal ions, best performance is at pH 7, the adsorption rate was 10% at pH 4. Adjusting the pH can achieve recovery of heavy metals ion and magnetic particles.

Effective application of dendrimers in the biomedical field. Magnetic nanoparticles modified by dendrimer terminated with amino groups can increase the loading capacity and stability of the Streptavidin-biotin, thereby improving affinity to biotin in the biomedical applications. Compared with unmodified magnetic nanoparticles, its SA adsorption performance was improved, and the adsorption performance increases with the generation enhances. In addition, nanoparticles modified by dendrimer has a good affinity to biotin, affinity to biotin of G5 dendrimer modified particles than the unmodified magnetic particles are increased 6.15 times.

Dendritic polymers products are widely used in the agriculture field. Currently, commercially available insecticides, herbicides, fungicides or plant hormones, agricultural preparations have the following disadvantages: decreased activity of the active ingredient, low surface energy, small void space, light degradation, and high cost etc. Dendrimers due to structural characteristics have absolute advantages compared with traditional products in this area: (1) thermal stability (2) longer activity time of the active ingredient (3) low-release effect (4) increase solubility (5) improve adhesion and permeability (6) improve permeability (7) reduce the adhesion of soil to make the active ingredient get the plant roots or soil to play the effect ( ![]() |

Dendrimer based magnetic nanoparticles in biomedical areas. Using coprecipitation to prepare double oleic Fe3O4 nanoparticles, first modified MMA in surface of magnetic nanoparticles and then modified with GMA, modified dendrimers by generation. The large number of amino groups and fluorescein isothiocyanate (FITC) combine to form a fluorescent magnetic beads with fluorescent, magnetic, multi-drug delivery characteristic. Dendrimer carried drug reaches the specified position by applying a magnetic field, to achieve the purpose of targeted drug delivery, the drug can be tracked as of the fluorescence. Dendrimer surface grafted variety of functional groups can be applied to different areas.

Dendrimer modified magnetic nano-materials as water treatment agent in the oil field. Using dendrimer with a special structure to coat magnetic iron oxide nano-particles to prepare water treatment agents of PF series of magnetic nano material modified by dendrimer, they have very good degreasing effect. At dosage of 50mg/L, oil removal rate can be up to 89.7%, far higher than 100mg/L Roman Haas with degreasing rate 66.6% .About suspended solids removal, water quality is clear and with no obvious suspended solids after the treatment of dendrimers based water treatment agents, while other agents suspended solids removal rate is low. This shows that the dendrimer-coated iron oxide magnetic nanoparticles greatly improved degreasing effect, not only played high adsorption role of magnetic iron oxide nano but also played bridging effect of dendrimer surface group.
