Abstract

Porphyrin is a type of polymer which can combine with multiple heavy metal ions.Some structures and properties of porphyrin will get changed with this combination.We can detect these changes of structures or properties of porphyrin to know how the combination between them goes on.In this paper,we get the giant porphyrin capsule in two consecutive micro-fluidic junctions.We can observe strong red fluorescence under green laser excitation.Then we use Mn²⁺ to react with this capsule.Mn²⁺ can combine with porphyrin and influence the intensity of the red fluorescence.Different concentration of Mn²⁺ solution has different effects on the intensity of fluorescence.So we can make sense of how the combination is between the two substance.
