Recent Study on Production and Evaluation of Antimicrobial Microcapsules with Essential Oils Using Complex Coacervation | Chapter 5 | Advanced Aspects of Engineering Research Vol. 6

 Today's needs and criteria for preventing infections during surgical procedures necessitate more creativity than ever before. The single-use textile substrates used in hospitals can also be employed to spread the antibacterial impact throughout the building. The major goal of this project is to use natural components to create antibacterial clothing and textile surfaces. Microencapsulation has demonstrated its ability to protect and vehiculize active principles that can be used in medical treatments on multiple occasions. Essential oils were utilised as an antibacterial agent in this study, and when mixed with shell polymers based on Chitosan with varying molecular weight distributions and Arabic gum, they were able to fight Gram (+) and Gram () bacteria. Chitosan has been demonstrated to be a biopolymer with a wide range of applications, but its molecular weight is extremely important. Due to its hydrogel-like characteristics, the examination of the efficiency of the final systems obtained presents highly valuable possibilities. In a layer by layer method (LbL), the influence of the molecular weight of biopolymers utilised has been established, and it provides a highly promising technique to assert a clear control over the delivery mechanisms. The essential oil used has a very volatile character generated by more than 40 components, and it was possible to confirm that all of its components were encapsulated using FT-IR and TGA. The impregnation of the various samples to the tissue was successful, allowing for the antibacterial research, which was carried out in duplicate on each sample and indicated bacterial activity.
