Injectable Gels

Traditional biomaterial scaffolds often require invasive surgical implantation, which carries associated risks and complications. Injectable hydrogels represent a paradigm shift, offering a platform for the minimally invasive delivery of advanced therapeutics and tissue engineering solutions. As liquid precursors that undergo a phase transition to form a three-dimensional (3D) scaffold in situ, these intelligent materials can perfectly fill complex tissue defects, provide localized and sustained therapeutic delivery, and mimic the native extracellular matrix (ECM) to support cellular regeneration.

Service Overview

Matexcel's custom injectable gels service is a collaborative, full-service R&D partnership. We are not just a supplier; we are an extension of your research team. We specialize in designing, developing, and validating bespoke hydrogel formulations tailored to your specific application. Our experts partner with clients in academia and industry to navigate the complexities of formulation and scale-up, bridging the critical gap between laboratory innovation and industrial application.

Technical Principles

The core technical principle of an injectable hydrogel is a precisely controlled sol-gel transition, where a low-viscosity polymer solution (sol) transforms into a solid 3D network (gel) after administration. At Matexcel, we engineer this transition using two primary crosslinking strategies:

• Physical Crosslinking: These systems utilize reversible, non-covalent interactions. Gelation is triggered in situ by environmental stimuli, such as a change in temperature (thermo-responsive), pH, or the presence of specific ions. We also design shear-thinning hydrogels that are pre-gelled but temporarily fluidize during injection and self-heal instantly upon delivery.
• Chemical Crosslinking: These systems form stable, irreversible covalent bonds to create a robust network. We can trigger this gelation using highly biocompatible mechanisms, including light exposure (photocuring), highly specific enzymatic reactions (e.g., HRP, transglutaminase), or rapid "click chemistry" reactions like Schiff base formation.

Technical Classification

Our development capabilities are built upon a comprehensive library of polymer platforms, allowing us to select the optimal material for your specific requirements:

Our Services

Matexcel provides a comprehensive, end-to-end service framework to accelerate your R&D and ensure robust, reproducible outcomes. Our services are structured to guide your project from concept to a fully validated biomaterial.

• Formulation Design: Collaborative consultation to define your project's Critical Quality Attributes (CQAs). We assist in selecting the optimal polymer, crosslinking mechanism, and additives to meet your target product profile.
• Custom Synthesis & Process Development: Bespoke "Customized Polymerization" and chemical modification (e.g., methacrylation) to create novel polymers, followed by process optimization for aseptic manufacturing and scalability.
• Comprehensive Physicochemical Characterization:

Rheological Profiling: Advanced analysis of viscosity, shear-thinning properties, and gelation kinetics (storage/loss moduli, G' and G'')—critical for guaranteeing injectability and in situ stability.

Structural & Mechanical Analysis: (FTIR, NMR, DMA, compression/tensile testing) to validate chemical composition and final mechanical performance.

Functional Testing: Characterization of swelling kinetics, equilibrium water content, in vitro degradation profiling (hydrolytic and enzymatic), and in vitro drug/protein release studies.

• Biocompatibility & Safety Validation: We provide a comprehensive in vitro data package aligned with international regulatory standards.

Our Service Advantage

As a "professional materials science research partner," Matexcel's key advantage is our vertical integration. We are not just a contract research lab; we are a primary developer and manufacturer of high-performance biomaterials (chitosan, hyaluronic acid, collagen, etc.) that form the basis of these advanced hydrogels. This provides us with "unmatched expertise" in material science, ensures rigorous quality control over all raw materials, and offers you a seamless, de-risked pathway from benchtop formulation to cGMP-compliant industrial scale-up.
