Embodiment 1
[0024] A method for constructing an electrochemically controllable bacterial adhesion interface, comprising the following steps:
[0025] 1) Preparation of dipyridylamine: Put 550 mg of paraformaldehyde and 2.8 g of lutamine in a 250 mL round bottom flask, add 15 mL of ethanol and 45 mL of water, and then add 1.0 g of p-hydroxyphenylpropionate Esters and 1.4 mL of 1.0 M hydrochloric acid, refluxed for 24h. The reaction mixture was cooled to room temperature and washed with saturated Na 2 CO 3 Neutralize to neutral, then extract the solution with excess chloroform. Na for organic phase 2 SO 4 After drying, chloroform was evaporated under reduced pressure. The crude product was purified by silica gel column chromatography (methanol:chloroform=5:95, v:v) to obtain a light yellow oily substance which was dipyridylamine. Its structure can be given by figure 2 shown 1 Confirmed by H NMR spectroscopy.
