Scheme 2.
(a) AFM images of the grafted fluorescent tetracycline-imprinted polymer (a1)/non-imprinted polymer (a2) nanoparticles. (The inset is a height profile of cross-section (white line)). (b) Profiles of a water drop on the films of the ungrafted and grafted fluorescent tetracycline-imprinted polymer/non-imprinted polymer nanoparticles. Photographs of nanoparticles dispersed in pure water (1 mg·mL−1) (c) without irradiation and (d) under 365-nm light irradiation. The samples from left to right in each figure are the ungrafted tetracycline-imprinted polymer (1)/non-imprinted polymer nanoparticles (2) and grafted tetracycline-imprinted polymer (3)/non-imprinted polymer nanoparticles (4).
