    What is Dendritic Polymer?

    Dendritic polymers are a type of synthetic polymer materials with three-dimensional structures. They are formed by repeated branching growth from the core molecule outward, and each repeating unit has a dendron, presenting a regular and controllable topological structure. The molecule can be spherical, with a cavity inside and rich functional end groups on the surface.

    What are the Features of Dendritic Polymers?

    Controllable Functionality‌

    The type and number of terminal groups can be controlled in a targeted manner, giving the material optical, catalytic, targeted drug release and other properties

    Monodispersity and Nanoscale‌

    The molecule itself has a nanoscale size, and the synthesis process can achieve precise control of molecular weight.

    High Biocompatibility‌

    Dendrimers are widely used in drug delivery and gene transfection due to their non-toxicity and degradability. ‌

    Question and Answer

    What is the difference between dendritic polymers and hyperbranched polymers?

    Dendritic polymers are highly symmetrical and can present a perfect sphere. Hyperbranched polymers are incompletely branched and have a fan-shaped structure.

    Dendritic polymers have a high density of terminal groups and are precisely controllable. Hyperbranched polymers have randomly distributed functional groups.

    Typical applications of dendritic polymers are targeted therapy and nanomaterials. Typical applications of hyperbranched polymers are industrial adhesives and toughening of composite materials.

    Which synthesis technologies exist for producing dendritic polymers?

    Dendritic polymer synthesis involves both divergent and convergent methods together with functional modification techniques to satisfy various requirements across biomedicine, catalysis, materials science and other domains. The synthesis efficiency and product purity remain on an upward trajectory due to the ongoing optimization of the divergent-convergent combination method along with the macromonomer method.

    How do dendritic polymers contribute to pharmaceutical applications?

    1. Drug delivery and targeted therapy: Dendritic polymers stand out as a drug carrier due to their ability to hold large drug quantities and deliver medications through variable release rates with precise targeting capabilities.
    2. Antibacterial properties: Because of their high branching structure and many terminal functional groups dendritic polymers demonstrate high reactivity towards microorganisms and thus serve as effective antibacterial materials.
    3. Biosensing: Biosensing applications frequently employ dendritic polymers due to their excellent molecular recognition and signal transduction properties.
