A dispensing device and method for forming at least partially solid or gel-like material from a liquid are described. In one example, at least one liquid issuing from an outlet is subjected to an electric field causing the liquid to form at least one electrically charged jet which, after formation, forms a fibre (F) or breaks up into fibre fragments (FF) or particles (D). The thus formed at least partially solid or gel-like material may be directly deposited, by virtue of the energy in the electrical field, onto a surface area, for example an area of skin enabling, for example, formation of a dressing for a wound or burn which is of high specific area and extremely absorbent. A biologically active ingredient such as for example a pharmaceutical ingredient or biological matter such as DNA may be incorporated into the fibres (F), fragments (FF) or particles (D). In another example, fibrils, particles or microcapsules incorporating a biologically active ingredient may be supplied for oral or nasal administration to an animal such as a human being. |
