Abstract: PEHAM dendrimers of the formula: Specific PEHAM dendrimers are used in a formulation with an active agent for agricultural purposes. In particular, the PEHAM dendrimers may be used for increasing the efficacy of the active agent in various ways, such as by improving solubility of the active agent in the formulation, by improving adhesion and penetration of the active agent to plant surfaces, or by improving the water-fastness of the active agent to the plant or seed. The PEHAM dendrimers may also increase the efficacy of the active agent by increasing soil penetration of the active agent to reach the plant roots or under soil parts, by reducing soil adhesion of the active agent to reach the plant roots or under soil parts, or by reducing enzymatic degradation of the active agent by the plant or seed or microorganisms in the soil.

Abstract: A device for the transdermal delivery of a therapeutic agent to a biological subject that includes a first electrode comprising a first array of electrically conductive microprojections for providing electrical communication through a skin portion of the subject to a second electrode comprising a second array of electrically conductive microprojections. Additionally, a reservoir for holding the therapeutic agent surrounding the first electrode and a pulse generator for providing an exponential decay pulse between the first and second electrodes may be provided.
