The subject invention finds utility in the area of gene therapy of diseases. More specifically, the invention concerns the making of a novel non-viral vector which can bind to desired DNA to form a combination useful to transfect diseased mitochondria of human or animal cells. The non-viral vector comprises a dequalinium salt subjected to standard liposome production procedures to obtain the vector named DQAsomes.

The subject invention concerns novel materials and methods for the delivery of substances into cells. In a specific embodiment substances are delivered into cells using a novel class of lipid compounds. These compounds, cationic lipid compounds having a disulfide bond, can be complexed with DNA to be inserted into a cell in gene therapy. Once inside the cell, enzymes present within the cell cleave the disulfide bond and the DNA is released.
