Introduction to TSM (Tannic Acid-based Mussel-inspired Hydrogel)

Ingredients & Mechanism
TSM is an advanced bioactive hydrogel inspired by the wet adhesion properties of mussels. The active ingredients primarily consist of Tannic Acid (TA), Silk Fibroin (SF), and therapeutic agents such as Minocycline Hydrochloride (MCH). Through hydrogen bonding between the amide bonds of SF and the phenolic hydroxyl groups of TA, a stable β-sheet network is formed. The therapeutic agent is then incorporated into this network via dynamic Schiff base reactions under mild aqueous conditions.

Its mechanism relies on its exceptional wet-adhesive capability within dynamic fluid environments. Upon application, the hydrogel forms a robust bond with tissue surfaces even in the presence of blood or saliva. This strong adhesion extends the local retention time of the material. Furthermore, the porous structure of the hydrogel allows for the controlled release of therapeutic agents through swelling and diffusion, providing sustained antibacterial and anti-inflammatory effects while maintaining a stable network structure in the body's microenvironment.

Product Advantages
The distinct advantages of TSM over traditional topical treatments include:

• Superior Wet Adhesion: Unlike conventional materials that lose stickiness when wet, TSM achieves high shear and tensile strength on moist tissue interfaces, ensuring it stays firmly in place during treatment.
• Sustained Therapeutic Release: The unique porous matrix facilitates the gradual release of active compounds, leading to long-lasting efficacy and reducing the need for frequent reapplication.
• Self-Healing Properties: The dynamic chemical bonds within the hydrogel grant it self-healing capabilities, allowing the material to recover its structural integrity after mechanical damage.
• Biocompatibility: Constructed from biocompatible components like tannic acid and silk fibroin, TSM demonstrates excellent safety profiles and minimal risk of immune rejection.

Suitable Population
This product is generally intended for the following groups, typically under professional medical supervision:

• Patients with Periodontal Conditions: Individuals suffering from periodontitis who require localized, long-term antibacterial therapy and tissue protection in the dynamic fluid environment of the oral cavity.
• Individuals Requiring Wound Management: Patients with soft tissue injuries or surgical sites where strong wet adhesion and sustained drug delivery are necessary to prevent infection and promote healing.
• Clinical Research Participants: Scientists and medical professionals investigating the efficacy of mussel-inspired biomaterials in tissue engineering and localized drug delivery systems.
