Abstract: Described and claimed is the combined use of an electric field and ultrasound to ablate a cell or tissue, the use of ultrasound to disrupt a nucleated cell which has previously been electrosensitised by exposure to an electric field, and the use of an electric field for sensitising a nucleated cell to ultrasound. We furthermore disclose the use of electricity to disrupt a nucleated cell which has previously been sensitised by exposure to ultrasound, and the use of ultrasound for sensitising a nucleated cell to electricity.

Abstract: The invention relates to a method for selectively releasing an agent loaded into a red blood cell, comprising electrosensitizing the red blood cell by application of an electric field and subsequently disrupting the cell selectively using ultrasound.

Abstract: A loading system for providing a cell suitable for delivery of an agent to a vertebrate, the system comprise a loading module for loading a cell with an agent; and a sensitisation module in fluid communication with the loading module, the sensitisation module for sensitising a cell to an energy field, such that said cell is induced to release the agent upon exposure to said energy field. The system can be used to transform a cell, such as a red blood cell, into a delivery vehicle for delivering a therapeutic agent and/or an imaging agent to a vertebrate, and in particular, to a mammal, such as a human being.
