Controllable unharness of Dopastat (DA) is price finding out for its vital in physiological metastasis. β-cyclodextrin/11-mercaptoundecanoic acid self-assembled monolayer (β-CD/MUA SAM) supported gas bonds network was created as simulated enzyme-containing biomembrane. DA interacted with β-CD supported building block chemical bond and fashioned inclusion complexes in surface-to-air missile, specifically DA@β-CD/MUA surface-to-air missile. The method|natural action|action|activity} process of DA from DA@β-CD/MUA surface-to-air missile disclosed the discharge behavior of DA from enzyme-containing biomembrane at molecular level. Positive biased potential as external input was applied at DA@β-CD/MUA surface-to-air missile, reducing the electric charge density of surface-to-air missile. The decrease of electric charge density of surface-to-air missile resulted within the weakening of chemical bond between DA and β-CD, that successively caused DA to be discharged. mistreatment scanning chemical science research, positive biased potential not solely had specificity induction for the discharge of DA, however additionally was able to monitor the discharge quantitatively in real time. These results showed that positive biased potential as external input was favorable for the governable unharness of DA, suggesting the doable application of biased potential in governable regulation field.
