Antimicrobial is closely related to public life and efficient delivery of drug and gene is an indispensable means for the modern medicine. However, guanidinium-rich polymer has particular function in antimicrobial and delivery, such as the bactericidal mode of guanidinium-rich polymer is the non-specific interaction—electrostatic interaction, which is the driving force of the movement for the process of guanidinium-rich polymer getting close to the cell membrane of microbes, and from the perspective of biological evolution, which make bacterial hard to evolve resistance. On the other hand, the tight double-hydrogen bonded structure between guanidino and phosphate in the cell membrane phospholipids is the foundation for guanidinium-rich polymer exhibiting excellent performance on delivery, which will be an important grasp for the guanidinium-rich polymer and its carrying molecules entering the mammalian cell membrane. Moreover, relatively lower toxicity or nontoxicity of guanidinium-rich polymer for the mammalian cells remove the obstacle of applications. Therefore, this paper is based on available literature, sums up the fabrication methods of guanidinium-rich polymer, reviews the applications in microbial inhibition and delivery of drug or gene.

Key words: guanidinium-rich polymer, microbial inhibition, drug delivery, gene delivery
