Abstract
In this work, isotherms for mixtures of methylene blue (MB(+)) and dim yristoyl phosphatidic acid (DMPA) were studied. Cc-spreading technique s were used to spread a mixed solution of MB(+) and DMPA in 3:1 CHCl3/ CH3OH at the air-water interface. This system exhibits markedly expand ed isotherms at low pi values. By using the Langmuir-Blodgett (LB) tec hnique, a 1:1 DMPA/MB(+) monolayer was transferred to an indium tin ox ide electrode at pi = 25 mN m(-1). The presence of MB + in LB films wa s detected by visible spectroscopy and electrochemical methods.
