Abstract: 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 from 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.

Abstract: A method of manufacturing a dosage form is described wherein a liquid solution of a biologically compatible polymer containing a suspension of particulate material that is insoluble in the polymer is supplied to a liquid supply tube (2) having an outlet (2a) and an electrical field is established between the outlet (2a) and a surface (19) spaced from the outlet (2a) to cause liquid issuing from the outlet to form a jet which dries to form a polymer fibre containing particles of the particulate material and which deposits onto the surface (19) to form a dosage which consists of said particulate containing fibre which fibre dissolves or disintegrates in a wet environment such as the mouth.

Abstract: A method of facilitating processes of mammalian cells such as at least one of attachment, movement, growth, proliferation and differentiation comprises: supplying liquid comprising biologically compatible polymer to a liquid outlet in the vicinity of a surface and subjecting liquid issuing from the outlet to an electric field to cause the liquid to form polymer fibre which is attracted to and deposits onto the substrate to form a polymer fibre scaffold having fibre of a given diameter with gaps between adjacent fibre portions; and applying mammalian cells to the fibre scaffold, wherein the gaps between the fibre portions and the fibre diameter have a size relative to a diameter of the mammalian cells such that cells grow or elongate preferentially along the fibre of the fibre scaffold. Apparatus for enabling carrying out of such a method is also described.

Abstract: An eye covering (700) for covering an exposed surface portion of an eye, the covering comprising a body having front and rear surfaces (702a and 701a) with the rear surface being shaped to conform to said exposed surface portion (701, 702) and at least a portion of the body comprising biologically compatible polymer fibre.
