Malaria is a life threatening disease for many people, especially in Africa. It is a vector borne disease, meaning that it is spread by infected mosquitos. Malaria can be stopped by preventing mosquitos to spread. Insecticide treated nets (ITNs) are a very useful tool for this. The use of ITNs resulted already in a 20% reduction in overall child mortality in Africa. The amount of insecticide on the ITNs gradually decreases over time. The nets therefore have to be retreated regularly. However the retreatment rate is very low (5%), reducing the effectiveness. In response to these low retreatment rates long lasting insecticidal nets, having a life time of four to five years, are being developed. This research focusses on the development of a controlled release coating for mosquito nets, applied by means of Electro HydroDynamic Atomization, also referred to as electrospraying. EHDA produces very fine droplets from a liquid by using an electric field. The produced spray can be used to cover the mosquito nets with a coating. By adding a polymer to the liquid that is sprayed, a controlled release coating can be obtained. Poly(vinyl acetate) is used because is easily dissolvable in acetone, without having influence to the conductivity…
