AMP | peptides | Anti-fouling, bactericidal capability, low cellular cytotoxicity, low antibiotic resistance | Structural complexity, expensive | [163] | ||
lotus leaf surface | super-hydrophobicity | Silane | Silicon based materials | Bactericidal capability, osseointegration performance | — | [164] |
Wing-shaped nanopillar structure of Cicada or dragonfly | bactericidal capability, self-cleaning property | Ti | metal | Bactericidal capability (S. epidermidis), hydrophobicity, low antibiotic resistance | — | [165] |
TiO2 | metal | Higher bactericidal capability (E. coli and S. aureus) | — | [166] | ||
ZnO | metal | Bactericidal capability (E. coli and S. aureus) | — | [167] | ||
FHA | Ceramic | Bactericidal capability, hydrophilic, good osseointegration | — | [168] | ||
bSi | Silicon substrate | Highly hydrophobic, bactericidal capability (P. aeruginosa and S. aureus) | Sterilization was less effective than previously reported | [169] | ||
SiO2 | Silicon substrate | Higher bactericidal capability efficiency | — | [170] | ||
PET | polymer | Bactericidal capability (E. coli and Klebsiella pneumoniae) | — | [171] | ||
PS-block-PMMA | copolymer | Dual bactericidal and bacteria-releasing function | — | [172] | ||
