However, there are still challenges in terms of the stability and controlled release of plant extracts within the nanofibrous matrix.

3. Conclusions from Existing Research

3.1 Efficacy of Nanofibrous Wound Dressings with Plant Extracts

Overall, the existing research indicates that nanofibrous wound dressings with plant extracts have great potential in wound healing. The combination can effectively reduce the wound healing time, decrease the incidence of infection, and improve the quality of healed tissue. The unique properties of nanofibrous materials combined with the bioactive components of plant extracts contribute to these positive outcomes.

3.2 Challenges in Current Research

• Stability of Plant Extracts: One of the major challenges is maintaining the stability of plant extracts within the nanofibrous matrix. Many plant extracts are sensitive to environmental factors such as temperature, humidity, and light. Their bioactive components may degrade over time, reducing the effectiveness of the wound dressing.
• Controlled Release: Achieving a controlled release of plant extracts is another difficulty. Ideally, the plant extracts should be released in a sustained and controlled manner at the wound site. However, current methods often result in either too rapid or too slow release, which can affect the wound - healing process.
• Biocompatibility: While nanofibrous materials are generally considered biocompatible, the addition of plant extracts may introduce new variables that need to be carefully evaluated. Ensuring that the combination is fully biocompatible with the human body is crucial for its clinical application.

4. Recommendations for Future Research

4.1 Improving Stability of Plant Extracts

• Encapsulation Techniques: Advanced encapsulation techniques can be explored to protect plant extracts from degradation. For example, microencapsulation or nano - encapsulation can create a protective shell around the plant extracts, shielding them from environmental factors.
• Selection of Appropriate Polymers: The choice of polymers for nanofibrous materials can also impact the stability of plant extracts. Polymers with good barrier properties can be selected to minimize the interaction between the plant extracts and the external environment.

4.2 Optimizing Controlled Release

• Design of Smart Release Systems: Smart release systems can be designed to respond to specific stimuli at the wound site, such as pH or enzyme levels. For example, a pH - sensitive nanofibrous dressing can release plant extracts more rapidly in an acidic wound environment, which is often associated with infection.
• Mathematical Modeling: Mathematical modeling can be used to predict and optimize the release kinetics of plant extracts. By understanding the factors that influence release, such as diffusion coefficients and fiber degradation rates, more precise control over the release process can be achieved.

4.3 Ensuring Biocompatibility

• In - vitro and In - vivo Studies: Comprehensive in - vitro and in - vivo studies should be carried out to evaluate the biocompatibility of nanofibrous wound dressings with plant extracts. These studies can help identify any potential cytotoxicity or immunogenicity issues at an early stage.
• Surface Modification: Surface modification of nanofibrous materials can be considered to enhance their biocompatibility. For example, the addition of bio - friendly coatings or functional groups can reduce the interaction between the dressing and the body's immune system.

4.4 Multifunctional Nanofibrous Wound Dressings

• Combination with Other Therapeutic Agents: Future research could explore the combination of plant extracts with other therapeutic agents, such as growth factors or antibiotics, within the nanofibrous wound dressings. This could create multifunctional dressings with enhanced wound - healing capabilities.
• Customization for Different Wound Types: Different wound types may require different properties from the wound dressing. Therefore, research should focus on customizing nanofibrous wound dressings with plant extracts for specific wound types, such as chronic wounds or burn wounds.

5. Conclusion
