Bipolar lipids are described which are able to form complexes with polyanions. The lipids comprise a cationic head linked to a hydrophobic backbone and a hydrophilic tail and are capable of self assembly to form stable complexes in aqueous solutions. The lipids are of particular use for the delivery of bioactive substances such as nucleic acids to cells in vitro and especially in vivo.

The present invention provides an albumin-binding compound essentially of the following elements: a spacer group, a water-soluble bridging group, a fatty acid chain and an acidic group characterised in that the acidic group is attached to the distal end of the fatty acid chain. The invention also provides an albumin-binding compound to which one or more biologically active moieties are attached.
