Liposomes have also been used as carriers for smaller drug carriers, such as cucurbiturils, to achieve a more controlled release of the drug into the targeted site in the body. In this study, we investigated the effects of cucurbit[7]uril, a macrocyclic organic compound, on the integrity of liposome lipid membranes. The average liposome size, measured by dynamic light scattering, increased with increasing concentrations of cucurbit[7]uril. In addition, fluorescence spectroscopy was used to calculate an association constant (\n                    <jats:italic toggle=\"yes\">K<\/jats:italic>\n                    <jats:sub>a<\/jats:sub>\n                    ) between cucurbit[7]uril and cholesterol of 3\n                    <jats:inline-formula>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" display=\"inline\" overflow=\"scroll\">\n                        <mml:mo>\u00d7<\/mml:mo>\n                        <mml:msup>\n                          <mml:mn>10<\/mml:mn>\n                          <mml:mn>6<\/mml:mn>\n                        <\/mml:msup>\n                        <mml:mo>\/<\/mml:mo>\n                        <mml:mrow>\n                          <mml:mi mathvariant=\"normal\">M<\/mml:mi>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    .

Thermogravimetric analysis demonstrated the localization of cucurbit[7]uril molecules on the surface of the liposomes. As the concentration of cucurbit[7]uril increased, the thermal stability increased, i.e. the mass loss of the liposomal suspension decreased. The biocompatibility of cucurbit[7]uril was also investigated using a hemolysis test on human red blood cells. In conclusion, the current study is the first to explain the relationship between lipid membranes and cucurbit[7]uril. The results of this study can be used to develop a new drug delivery system comprising liposomes and cucurbit[7]uril.\n
