Abstract
The present invention relates to a polymer complex for recognizing Helicobacter pylori and its uses, and in more detail, a water-soluble polymer-photosensitizer complex in which sialyllactose, which selectively binds to the surface of Helicobacter pylori, is conjugated, has excellent selectivity and binding power to the Helicobacter pylori strain, and the photosensitizer in the complex generates singlet oxygen when irradiated with laser to effectively induce the inactivation of Helicobacter pylori and it is intended to provide the complex as a polymer complex for recognizing Helicobacter pylori to effectively detect Helicobacter pylori in the gastrointestinal tract and to provide a Helicobacter pylori photodynamic therapy to solve the conventional antibiotic resistance problem.
