The invention discloses a method for preparing a diethylstilbestrol molecularly imprinted electrochemical sensor based on electropolymerization of a p-aminothiophenol film. The method comprises sequential steps such as glassy carbon electrode pretreatment, electrode modification by multi-wall carbon nanotubes, electrode modification by nano gold, functional monomer self-assembly, template molecular pre-assembly, electropolymerization of the p-aminothiophenol film, and template molecule elution, and an organic phase as a polyelectrolyte solvent improves the number and selectivity of binding sites in a polymer film, and is beneficial to formation of a stable host-guest compound from a template molecule and a function monomer, so that the template molecule can maintain a good rigid structurein a polymer network structure and form a cavity with a memory effect. The preparation method is simple and easy to control, and the sensor has strong selectivity and stability, high sensitivity and low cost. The sensor is suitable for analysis and detection of diethylstilbestrol residues in animal-derived foods, feeds and other samples.

The invention provides a photodynamic sterilization polymer as well as a preparation method and application thereof. The polymer is composed of a main chain and a side chain; the side chain is composed of a long alkyl chain with a quaternized tail end and can be combined with the surface of bacteria with negative charge to form a tight combined body, so that a bacterial membrane is transparent; the main chain is composed of benzene, fluorene and thiophene and has a relatively strong rigid structure; under a light illumination condition, the main chain is excited by light to sensitize air in the periphery to generate active oxygen, so that an efficient sterilization effect is realized. The polymer can be used as an antibacterial agent and can be used for killing gram positive bacteria and gram negative bacteria; the polymer also can be used for killing fungi and has a broad-spectrum antibacterial function. The polymer is simple to prepare and moderate to react and has relatively high yield. The polymer is used as an efficient photodynamic antibacterial material, concentration needed by sterilization is low and the light dosage is small; common white illumination can reach an efficient sterilization effect. The polymer provided by the invention emits fluorescent light in a long-wave region and also can be used for biological fluorescent imaging.
