ADSL and infection: An efficient method to inhibit infection of the biomaterial is to modify its surface with antibacterial agents containing silver, antibacterial polymers, antibiotics, etc.13, 14, 15, 16, 17 Among these, the antimicrobial peptides (AMPs) hold great potential due to their high antibacterial activity, low drug‐resistance, and specific metabolic pathways.18 Until now, more than 2300 AMPs have been identified from natural sources.19 In addition, many synthetic AMPs, especially those with short sequence, have been rationally designed.
