Application

  • Schiff Base-Based Hydrogel for Wound Healing: Research has developed a hydrogel using Schiff base chemistry embedded with silver nanoparticles capped by a hyaluronic acid-diethylenetriamine derivative, specifically aimed at enhancing wound healing applications. This innovative approach leverages the unique properties of diethylenetriamine in creating effective therapeutic materials (Martorana et al., 2024).
  • Photocatalytic Treatment of Wastewater: A study has utilized CdBi(2)S(4)-decorated aminated polyacrylonitrile nanofibers, involving diethylenetriamine, for the photocatalytic treatment of Cr(VI) and tetracycline in wastewater. This application highlights diethylenetriamine′s role in enhancing the environmental cleanup capabilities of photocatalytic materials (Du et al., 2024).
  • pH-responsive Drug Delivery Systems: Collagen/functionalized cellulose nanofibril composite aerogels, modified with diethylenetriamine, exhibit pH-responsive characteristics ideal for targeted drug delivery systems. This application demonstrates the versatility of diethylenetriamine in biomedical engineering, particularly in developing responsive delivery vehicles (Yue et al., 2024).
