I. [Product Description]
PASP-PEG-COOH is an amphiphilic block copolymer that combines the biocompatibility of polyaspartic acid with the steric hindrance effect of polyethylene glycol (PEG). It can be used as a high-performance organic intermediate or pharmaceutical intermediate, suitable for the construction of catalytic systems and the synthesis of functional materials. Its carboxyl terminal provides efficient chemical modification sites, enabling precise control of molecular self-assembly behavior.

III. [Application Fields]
    1. Polymer material synthesis: Used as a block copolymer template to prepare nanoparticles with controllable pore sizes.
    2. Nanomaterial preparation: Forms micelle or vesicle structures through self-assembly for carrier systems.
    3. Bioconjugation technology: The carboxyl active site undergoes a condensation reaction with amino groups to modify biomolecules.
    4. Catalyst carrier: Immobilizes metal nanoparticles to improve the stability of the catalytic system.
    5. Surface modification material: Improves the hydrophilicity and anti-protein adsorption performance of materials.
