| Abstract: | An atomic force microscope was used to observe the adsorption of phospholipid molecules(phospha-tidylcholine, PC) on the mica substrate.The film-formation by PC molecules adsorption spontaneously on the specific substrate has been proved. It is revealed that the evident differences of morphology exist among different sampler with different concentrations of PC/decane solutions. different adsorption times, etc.The effect of tip-induced change in size of domains formed by adsorption of PC molecules on the substrate during the AFM scanning was observed. |
