I. [Product Introduction]
MA-PEG-SPDP is a multifunctional organic intermediate that combines the polymerizability of methacrylate, the biocompatibility of the PEG chain, and the reversible disulfide bond cross-linking property of the SPDP group. As an efficient catalyst and functionalization modification tool, this compound is widely used in the fields of bioconjugation, polymer material synthesis, and nanocarrier construction, and is one of the core raw materials for the development of pharmaceutical intermediates.

III. [Application Fields]
1. Bioconjugation of macromolecules: Achieve the controllable connection between proteins/antibodies and PEGylated carriers through the disulfide bond exchange mechanism of SPDP.
2. Functionalization of nanomaterials: Used for the reversible surface modification of nanocarriers such as liposomes and polymer micelles.
3. Preparation of responsive hydrogels: The methacrylate group supports photo-initiated cross-linking to construct intelligent responsive materials.
4. Targeted drug delivery systems: Release drugs in response to the intracellular environment mediated by disulfide bonds.
5. Interface engineering of biosensors: The PEG spacer arm optimizes the immobilization density and orientation of biorecognition elements.
