As chronic wounds, diabetic ulcers, surgical incisions, and other wound types become increasingly complex, traditional dressings gradually reveal limitations in moisture retention, antibacterial properties, breathability, and bioactivity. To meet the modern demands for efficient, safe, and smart wound care solutions, functional hydrogel materials have emerged. PAM/CS hydrogel (composed of polyacrylamide and chitosan) demonstrates remarkable advantages in wound healing due to its excellent gel-forming ability, biocompatibility, and tunable properties.

Taskcm possesses mature PAM/CS hydrogel preparation technology and customization capabilities, providing clients with multi-specification, multi-performance hydrogel products to meet different stages of pharmaceutical R&D needs.

Product Introduction

Product Name: PAM/CS Composite Hydrogel Dressing

Product Overview:
This product is a soft, transparent, three-dimensional hydrogel network that can be directly applied to the wound surface. It offers excellent fluid absorption, film-forming ability, and bioactivity to accelerate wound repair. It is suitable for a variety of wound care applications.

Technical Parameters:

• Gel water content: >90%
• pH adaptability: 4.5–8.0
• Biodegradability: High
• Antibacterial efficacy (inhibition rate): >95% (against E. coli and S. aureus)

Material Composition:

• Polyacrylamide (PAM)
• Chitosan (CS)
• Deionized water
• Crosslinking agents (optional, natural/biodegradable)

Physical Properties:

• Excellent softness and adhesion to wound surfaces without displacement
• Microporous structure supporting gas exchange and exudate absorption
• Non-adhesive to wounds, reducing pain during dressing changes

For drug-loading applications, the hydrogel surface or structure can be functionally modified, enabling precise design of drug release profiles.

Product Advantages

Performance Advantages:

• Combines PAM’s strong gelation with CS’s natural antibacterial properties
• Good mechanical strength and bioactivity
• Maintains a moist wound environment while preventing infection

Core Functions:

• Prolonged hydration, promoting granulation tissue growth
• Antibacterial and anti-inflammatory effects to reduce infection risk
• Adjustable drug delivery system for controlled release
• Facilitates epithelial cell migration, accelerating wound closure

For drug encapsulation, Taskcm offers precise custom hydrogel services, extending drug efficacy and enhancing stability across various drug types.

Comparison with Competing Products:

• Superior bioactivity and comfort compared with traditional nonwoven fabrics, foam dressings, and silver-ion dressings
• Composite PAM/CS hydrogel shows synergistic properties compared with single-component PAM or CS hydrogels

Economic Advantages:

• Mature synthesis process with controllable costs
• Supports large-scale and customized production
• Longer usage cycles reduce replacement frequency and overall care costs

Cost-effectiveness:

• Stable raw material sources
• Supports single-use and multiple-use formats
• Economically friendly for both medical institutions and patients

Application Scenarios

• Surgical incision dressings
• Diabetic foot ulcer care
• Venous ulcer care
• Pressure ulcers and trauma care
• Post-medical-aesthetic treatment dressing

Taskcm’s robust pilot-scale platform allows lab-formulated hydrogels to be scaled up rapidly to industrial levels, ensuring smooth transition to clinical and commercial stages.

Implementation Plan

Design Stage:

• Determine drug loading, gel strength, and thickness according to customer requirements
• Provide multiple formats (patch, injectable, pre-formed dressing)

Manufacturing:

• Controlled temperature and vacuum stirring synthesis
• Key production steps compatible with GMP standards for medical-grade output
• Large-scale production capacity ensures continuous supply

Installation and Use:

• Sterile packaging for direct use in hospitals or at home
• User manuals and instructions reduce operational complexity

Maintenance and Storage:

• Stable for over 6 months under low-temperature conditions
• Easy disposal after use without special treatment

Conclusion

PAM/CS hydrogel represents a new generation of medical dressings, excelling in moisture therapy, antibacterial control, controlled drug release, and biocompatibility. It is a highly promising solution for wound repair in pharmaceutical R&D.

Taskcm looks forward to collaborating with R&D institutions and pharmaceutical companies to advance hydrogel technology applications and meet diverse medical research needs, maximizing industrial value.

In the future, this material may further integrate smart responsive mechanisms (e.g., temperature-sensitive, pH-responsive) and expand into wearable medical dressings and self-healing wound repair systems, supporting precision therapy and personalized care development.
