Conventional antibiotics has saved countless human lives, however, is seriously challenged by the quick emergence of antibiotic-resistant pathogens. It is urgent to develop new types of antimicrobial agents to treat antibiotic-resistant microbial infections.

However, natural HDPs are structurally unstable due to their easy hydrolysis by proteases.
