Facile and Cost-Effective Development of Silver based Cellulosic Wound Dressing using Electrospraying Process

Silver-based wound dressings are deployed for various types of wounds due to its broad antimicrobial activity. Most of the wound dressings are prepared by exhaustion or doping process, which requires excess quality of silver to be used and also leads to burst release. Electrospraying process provides an excellent opportunity to topically apply silver on cationic cellulosic substrates. The cationization of cellulose ensures better bonding of silver nanoparticles thereby ensuring durability for long periods. The developed wound dressing exhibited excellent antimicrobial activity against E. Coli and S. Aureus.

Automated summary

By topically applying silver on cationic cellulosic substrates using the electrospraying process, better bonding of silver nanoparticles is ensured, resulting in long-term durability and excellent antimicrobial activity of the developed wound dressing.
