Custom Polymer ModificationAdvanced Drug Delivery CarriersPEGylation Contract Services
We provide end-to-end PEGylated chitosan services, combining expertise in polymer chemistry, PEGylation techniques, and nanomaterial engineering to deliver reliable solutions for research and industry. Our service includes not only the synthesis of PEG–chitosan conjugates with tailored chain lengths and substitution degrees, but also optimization for solubility, stability, and biocompatibility to meet biomedical standards. Whether your goal is to develop novel drug delivery systems, design advanced biomaterials, or explore new formulations, our team ensures consistency, scalability, and scientific rigor in every project.
Traditional chitosan suffers from poor water solubility, limited stability at physiological pH, and inconsistent performance in drug delivery systems. Our PEGylation technology solves these pain points by:
Improving solubility and dispersibility across a wide pH range
Enhancing biocompatibility and reducing immunogenicity
Extending circulation time in vivo through "stealth effect" shielding
Increasing formulation stability for nanoparticles and hydrogels
Enabling multifunctional modification with targeting ligands, dyes, or therapeutic molecules
These improvements make PEGylated chitosan an ideal platform for nanoparticle drug delivery, gene carriers, tissue engineering scaffolds, and advanced biomedical applications.

Application Consulting
We start with an in-depth consultation to understand your specific application needs, such as drug delivery, biomaterial development, or nanoparticle formulation. Together, we define the technical requirements, target specifications, and expected outcomes.
Our experts propose a tailored PEGylation strategy, selecting the optimal PEG chain length, conjugation chemistry, and substitution degree. A synthesis plan is drafted, ensuring scalability and reproducibility.
We carry out PEGylated chitosan synthesis under controlled conditions, optimizing reaction parameters for maximum efficiency and batch consistency. Early samples can be provided for client validation.
Each batch undergoes comprehensive analysis (NMR, FTIR, GPC, zeta potential, solubility testing) to confirm PEGylation success and ensure compliance with client specifications.
Once validated, the process is scaled up to deliver research-grade or preclinical quantities, maintaining quality assurance through every stage.
We provide full documentation, data reports, and continued technical support, including consultation on application integration, regulatory requirements, and future scale-up strategies.
We offer highly flexible PEGylated chitosan synthesis with precise control over PEG chain length, grafting ratio, and functionalization, ensuring that every project receives a material perfectly matched to its application.
Our technology improves chitosan's water solubility and stability across physiological conditions, delivering materials that are safe, reliable, and effective in biomedical environments.
Each product is validated using advanced techniques (NMR, FTIR, GPC, and more), guaranteeing reproducibility, transparency, and full confidence in material performance.
From milligram-scale research samples to gram-scale pilot batches, we provide seamless scale-up services, enabling clients to transition smoothly from lab R&D to preclinical development.
Beyond material synthesis, we guide clients through formulation design, regulatory considerations, and integration into drug delivery or biomedical systems, reducing risk and accelerating project success.
PEGylated chitosan is a biopolymer created by chemically conjugating polyethylene glycol (PEG) with chitosan. This modification improves solubility, stability, and biocompatibility, making it ideal for biomedical and industrial applications.
A: While natural chitosan has limited solubility and stability at physiological pH, PEGylated chitosan overcomes these limitations by increasing hydrophilicity and reducing immunogenicity, allowing broader use in drug delivery and tissue engineering.
Yes. We support multiple scales - from milligram-level research quantities to multi-gram preclinical pilot batches - with consistent quality and detailed analytical validation.
We offer a variety of PEG chain lengths (2k-20k Da) and functional end groups (amine, carboxyl, thiol, azide, etc.) to match your project's specific chemical and biological requirements.
