09/2013 microcapsules of vanillin to fight bacteria

vanillia Metor


A group of URV researchers led by Doctor Ricard Garcia-Valls has taken advantage of the antibacterial properties of vanillin to develop microcapsules that can be incorporated into fabrics and thus create antibacterial curtains. The work has been carried out by the research group at the METEOR-Centre for Membrane Technology and Engineering Processes of the URV in collaboration with Doctor Magdalena Constantí of the Nanobiotechnology and Bioanalysis Group.


.This new study has opened up the possibility of developing curtains with an antibacterial layer that resists odours and gives off a scent of vanilla. The technology has been developed at the URV and opens the door to new medical applications in preventing the spread of hospital infections through bed linen and other objects. The results of the research have been published in an article in the scientific journal Industrial & Engineering Chemistry Research of the American Chemical Society.

The article points out that vanillin (the principal ingredient in the vanilla extract that can be found in any supermarket) offers more than just a pleasant smell because it can also combat microbes including Staphylococcus aureus, a bacterium responsible for many of the infections contracted in hospitals. The research team decided to use microcapsule technology as a means of incorporating both the fresh aroma and the antibacterial properties of vanilla into curtains.

This has resulted in the microencapsulation of vanilla in small capsules made of polysulfone, a heat resistant plastic. These capsules were then embedded in layers of cotton. The study shows that curtains containing these microcapsules resist the growth of Staphylococcus aureus bacteria and that the coating remains intact after several dry-cleaning cycles. The scientists believe that this research has opened the way for the development of further antibacterial and pleasant smelling fabrics.
