Combatting Helicobacter pylori: A Focus on Nanomaterials

Developing effective non-antibiotic antimicrobial strategies is essential for combating global antibiotic resistance, including resistance stemming from Helicobacter pylori (H. pylori) treatment. Nanomaterials offer a promising and innovative approach for non-antibiotic anti-H. pylori treatment strategies. This review highlights the progress made in the use of metallic and nonmetallic nanoparticles, as well as nanozymes, to directly inhibit H. pylori growth. Moreover, we summarize advances made in the direct targeting of H. pylori by nanomaterials and the stimuli-responsive release of nanoparticles in the stomach. Additionally, we explore the recent advancements in multifunctional nanoplatforms that integrate physical methods, such as light, heat, ultrasound, and magnetism, with nanomaterials to synergistically treat H. pylori infections. Finally, we briefly address the existing challenges and future directions in this field. In summary, we highlight that with ongoing research, nanomaterials may serve as a promising treatment strategy for H. pylori eradication.
