In order to test the effect of binding between CsgASpyCatcherHisTag mutant and inorganic nanoparticles, we apply same amount of suspended QDs solution into M63 medium which has cultured biofilm for 72h. After 30-min incubation, we used PBS to mildly wash the well, and the result was consistent with our anticipation: On the left, CsgASpyCatcherHisTag mutant were induced and thus secreted biofilm, and firmly attached with QDS and thus show bright fluorescence. Therefore, we ensure the stable coordinate bonds between CsgASpyCatcherHisTag mutant and QDs can manage to prevent QDs from being taken away by liquid flow.

CsgASpyCatcherHisTag

This is the subunit of the biofilm of E. Coli Curli system linked to SpyCatcher and HisTag. The two added parts can be used for various functions with SpyTag and other His tag-binding materials like quantum dots.

Fluoresence Binding Test In order to test the effect of binding between CsgASpyCatcherHisTag mutant and inorganic nanoparticles, we apply same amount of suspended QDs solution into M63 medium which has cultured biofilm for 72h. After 30-min incubation, we used PBS to mildly wash the well, and the result was consistent with our anticipation: On the left, CsgASpyCatcherHisTag mutant were induced and thus secreted biofilm, and firmly attached with QDS and thus show bright fluorescence. Therefore, we ensure the stable coordinate bonds between CsgASpyCatcherHisTag mutant and QDs can manage to prevent QDs from being taken away by liquid flow. <img>
