Methods are described of delivering biological material, which methods include the steps of providing a liquid formulation containing the biological material, supplying the liquid formulation to an outlet and subjecting liquid issuing from the outlet to an electrical field thereby causing electrohydrodynamic processing of the liquid without denaturing the biological material. In one example, the liquid formulation is provided by removing salts form a formulation containing biological material that does not denature in alcohol and then adding an alcohol to the formulation before supplying the liquid formulation to the outlet. An acid may be added to the liquid formulation before supplying the liquid formulation to the outlet.

L'invention concerne des procédés permettant de distribuer une matière biologique, qui consistent à obtenir une formulation liquide contenant la matière biologique, à acheminer la formulation liquide à une sortie et à soumettre le liquide sortant de la sortie à un champ électrique, ce qui entraîne un traitement électrohydrodynamique du liquide sans dénaturation de la matière biologique. Dans un mode de réalisation, la formulation liquide est obtenue par élimination des sels d'une formulation contenant une matière biologique qui ne se dénature pas dans l'alcool puis par addition d'un alcool à la formulation avant d'acheminer la formulation liquide à la sortie. Un acide peut être ajouté à la formulation liquide avant d'acheminer cette dernière à la sortie.
