  • Controlled release of moquito[!] repellents by cyclodextrins treated textiles [Elektronski vir]
    Miro Specos, M. M. ...
    Cyclodextrins are cyclic oligosaccharides which can form inclusion complexes with a large number of organic molecules, acting as reservoir for functional agents, such as mosquito repellents. They can ... be fixed to cotton surfaces by forming ester bonds with poly carboxylic acids. Beta-cyclodextrins were fixed to cotton fabrics via citric acid. Their content and permanence on the substrate after several washing cycles was evaluated by gain in mass, phenolphthalein test and infrared spectroscopy. Citriodiolr, a mosquito repellent derived from a natural source, was incorporated to beta-cyclodextrin treated textiles to obtain long lasting and reloadable mosquito repellent fabrics. Citriodiol release kinetics from treated fabrics was evaluated by gas chromatography. Repellent activity was monitored by exposure of a human hand and arm covered with the treated fabrics to Aedes aegypti mosquitoes. Mosquito repellent fabrics may constitute an alternative for the control of diseases caused by vector transmission such as dengue and yellow fever in rural areas from developing countries.
