The present invention aims to provide a cationic lipid that can be used as a nucleic acid delivery carrier, a lipid membrane structure using a cationic lipid, a nucleic acid-introducing agent using a cationic lipid, and a method of achieving nucleic acid introduction by using a nucleic acid-introducing agent containing a cationic lipid. A lipid membrane structure containing a cationic lipid represented by the formula (1)
wherein each symbol is as defined in the DESCRIPTION, is superior in the stability in blood and tumor accumulation property. A nucleic acid-introducing agent using the cationic lipid can achieve high nucleic acid delivery efficiency of nucleic acid to be delivered into the cytoplasm.

Readily available hydrophilic and small organofluorine moieties were condensed via “click chemistry” to generate nonionic hydrophilic fluorinated molecules with unique
19
F MR signatures. These were used to fabricate stable liposome formulations for imaging various tissue types. This approach was tailored to exploit the broad spectrum of organic
19
F molecular species and to generate probes with distinct
19
F MRI signatures for simultaneous assessment of multiple molecular targets within the same target volume.

Water soluble fluorogenic sensors for detecting a hydrazine analyte are provided. Aspects of the fluorogenic sensors include at least one water soluble group and a hydrazine reactive group. Methods of evaluating a sample for the presence of a hydrazine analyte and methods of detecting hydrazine diffusion across a phospholipid membrane are provided. Kits for practicing the subject methods are also provided.
