    Here we describe a novel strategy of liposome aggregation employing DNA-surfactant, in which the aggregation of liposomes can be reversibly controlled by enzyme stimuli and temperature. Single-stranded oligonucleotides were tethered to the outer surface of liposomes. Mixing of the DNA-tagged liposomes with ones bearing complementary DNA strands initiated the aggregation of liposomes. The liposomes were linked with each other via duplex DNA. The aggregated liposomes were dissociated by restriction enzyme to produce the initial discrete liposomes and re-aggregated by ligase.
