将羧基结合到直链淀粉中，形成了一种独特的刺激响应型超分子体系，该体系对具有重要生物学意义的多胺具有明显的颜色变化。当将精胺加入含有碘和羧基修饰的直链淀粉的水溶液中时，溶液明显从无色变为蓝紫色。这种颜色变化归因于碘被包裹到直链淀粉的螺旋空腔中，这是由直链淀粉和精胺之间的静电结合所触发的。
Incorporation of carboxyl groups into amylose led to a unique stimuli-responsive supramolecular system that shows distinct colour change in response to biologically important polyamines. When spermine was added to an aqueous solution containing iodine and amylose modified with carboxyl groups, the solution clearly changed from colourless to bluish purple. This colour change was attributed to the encapsulation of iodine into the helical cavity of amylose, which was triggered by the electrostatic association between the amylose and spermine.
