Abstract
A substance of interest is contained in nanospheres which are then encapsulated in fusogenic liposomes to prepare transport carriers that allow physiologically active substances, especially those having high molecular weight such as proteins and genes, to be introduced into cells efficiently and which permit the introduced active substance to be released in the cell at controlled rate. The fusogenic liposomes are prepared by conferring the fusogenic capability of Sendai virus to known liposomes.
