Studies on Improving Milk Characteristics

Sutures used to repair lips that have lost integrity due to Trauma or surgical causes are being developed with antimicrobial, drug-releasing, cellular, and intelligent designs to minimize surgical site infections, scarring, inflammation, and pain like conditions.

Antimicrobial Sutures

Bacterial adhesion and proliferation on the surfaces of biomaterials constitute a significant risk for surgical site infections. Although Antibiotic treatments help eliminate infections, their prolonged use can lead to bacterial resistance resistance. To achieve antimicrobial and anti-inflammatory effects at the surgical site, researchers have focused on modifying the surface composition and inorganic components of sutures. For this purpose, various antibacterial agents and silver nanoparticle-enhanced suture studies have been conducted. Triclosan is the antimicrobial agent currently used in sutures due to its efficacy and low toxicity in humans. Studies on triclosan-coated sutures have demonstrated that they inhibit bacterium growth and exhibit bacteriostatic activity without compromising the mechanical properties of the suture.

Drug-Releasing Sutures

Drug-releasing sutures alleviate postoperative complications and accelerate wound healing. Their primary advantage lies in delivering drugs locally at the wound site while maintaining continuous release without exceeding systemic toxic thresholds. Drug-loaded sutures can be produced using methods such as coating and electrospinning. Key considerations in production include achieving adequate drug loading without compromising the suture’s mechanical strength and ensuring controlled drug release.

Stem Cell Sutures

Sutures containing growth factors or cell stem cells can serve as scaffolds in tissue engineering and regenerative medicine by promoting fast healing, wound repair, and tissue regeneration within short timeframes. The primary objective of using stem cell sutures is to increase cell numbers at the wound site to accelerate tissue renewal and repair. However, maintaining the mechanical properties of sutures when used as cell carriers in wound treatments remains a significant challenge.
