We report on a simple and effective ultrasound-assisted deposition of vanillin nanoparticles (∼50 nm in size), raspberry ketone (RK) nanoparticles (∼40 nm in size) and camphor nanoparticles (width ∼30 nm, length ∼40 nm in size) on textiles and on polypropylene surfaces. The excellent antibacterial and antifungal activity of the fragrant coatings on cotton bandages, and polypropylene surface against Escherichia coli (E. coli), Salmonella paratyphi A (S. paratyphi A) and the yeast Candida albicans (C. albicans) cultures was demonstrated. It is worth pointing out that these fragrant materials are edible, making them very useful for packaging. The mechanism of the edible fragrant coating formation and adhesion to the textile was discussed, and finally an up-scaling of the sonochemical process for textile coating was carried out.
