| 中文摘要 | supramolecular assemblies of liposomes (vesicles) made of diacetylenic lipids and synthetic mannoside derivative glycolipid receptors were successfully used to mimic the molecular recognition occurring between mannose and escherichia coli. this specific molecular recognition was translated into visible blue-to-red color transition (biochromism) of the polymerized liposomes, readily quantified by uv-visible spectroscopy. some transition metal cations (cd2+, ag+, cu2+, fe3+, zn2+ and ni2+) and alkali earth metal cations (ca2+, mg2+ and ba2+) were introduced into the system to analyze their effects on specific biochromism. results showed that the presence of cd2+, ag+, ca2+, mg2+ and ba2+ enhanced biochromisin. a possible enhancement mechanism was proposed in the process of bacterial adhesion to host cells. however, cu2+, fe3+, zn2+ and ni2+ exhibited inhibitory effects that cooperated with diacetylene lipid with a carboxylic group and increased the rigidity of the liposomal outer leaflet, blocking changes in the side chain conformation and electrical structure of polydiacetylene polymer during biochromism. |
