Exposure of AMP’s improved antibacterial behavior on Ti-pNIPAM-AMP. (a) Quantitative antibacterial activity of different surfaces after incubation agtainst S.aureus and E.coli for 2h with an agar plate method, suggesting the antimicrobial activity of the Ti-pNIPAM-AMP surface was responsive to tyemperature. Ti-pNIPAM-AMP presented the most antimicrobial activity among difference surfaces, in particular, when temperature was set at 25◦C. (b) Antibacterial activity of free AMPs at different temperatures after incubation against S.aureus and E.coli for 2h. The results indicated that free AMP presented excellent antimicrobial activity at different temperatures.
