• 1. Dendritic nano catalysts can greatly enhance the catalytic activity
of the push agent.
• Nanoparticles prepared by the dendritic template has uniform size, as
catalyst can significantly improve the catalytic activity of the push
agent. Dendrimer on the surface of nanoparticles is curled state in air
or poor solvents, while it’s non-curled state in good solvents such as
alcohols,it’s stretched state, thus affecting the performance.
Dendrimers-OH was used as template to prepare Pt nanoparticles, in
the gas phase it doesn’t adsorb carbon monoxide. While in ethanol,
the adsorption amount was significantly increased, substantially
saturated after 1 hour adsorption. Weihai CY Dendrimer Technology
Co., Ltd.-Professional Manufacturer for low cost dendritic polymers.
-The newest 4th class polymers.

• 2. Dendrimers

as drug carriers have excellent targeting property.

• Dendrimers as drug carriers have good performance as its unique
cavity structure and a lot of end groups, such as adequate drug
loading, long-term cycle, better drug targeting, drug release
controllability, and little or no toxicity. Anticancer drug loaded by
dendrimers has good targeting and long-term retention, it has
stronger vascular permeability to lesions, but in normal tissues has
weak permeability, even in normal tissues will loop out and enter into
the diseased tissue again. Drug can be loaded onto dendrimer in two
ways. Non-covalent interaction, hydrogen bonding, hydrophobic
interactions, ion electrostatic interaction; covalent interaction,
including graft drug on the surface of dendrimer by chemical reaction.
Dendrimers have been used as drug carriers for methylamine purine,
paclitaxel, fluorouracil anticancer drugs in vivo animal experiments,
have good load targeting.

• 3. Application

of dendrimer in biomedical field.

• Caries has been recognized as the most common chronic
disease, and dental caries formation process is
irreversible. Looking for a dental hard tissue similar with
biological material, inducing dental hard tissue healing fix
will have important clinical implications. Dendrimer was
used as a template to control the formation of inorganic
substance, simulate enamel mineralization and
crystallization processes, to prepare a microstructure
material with unique structural features and biological
properties. Verification shows that, in the physiological
environment, carboxyl-terminated dendrimers induced
enamel to achieve its biomimetic mineralization, thus
achieving the purpose of dental hard tissue regeneration.

• 4. Dendrimers

modification impact on water vapor
permeability of microfiber synthetic leather.

• Leather substrate was synthesized by glutaraldehyde
cross-linked dendrimer and microfiber, increasing the
functional group content, so that the health performance
of fabric was improved. Process under optimum
conditions show that microfiber synthetic leather, tear
strength improved by 27.95% compared with preunhydrolyzed, the tensile strength increased by 23.95%,
water vapor permeability improved by 96.72%, elongation
at break increased by 57.21% ,amino group content
increased by 330.61%.

• 5. Great performance of dendrimers in composite
nanofiltration membrane field.
• Polysulfone ultrafiltration membrane was used as
support layers, composite nanofiltration
membrane was prepared by polymerization of
dendrimer and TMC,after interfacial
polymerization, active separating layer was on
the surface of the ultrafiltration membrane to
retain multivalent salt and captured molecular
weight is around 600~1000g/mol, has been
applied in water softening and depth of bleaching
treatment and industrial wastewater treatment.
