Prevention of bacterial colonization on non-thermal atmospheric plasma treated surgical sutures for control and prevention of surgical site infections

FTIR spectra of sutures before and after NTAP treatment.
Chemical modifications caused on (A) PGLA, (B) PGA, (C) PDO and (D) PGCL sutures by 7-minute NTAP treatment was evaluated by using FTIR. FTIR spectra revealed that, 7-minute NTAP treatment, caused a decrease in relative absorption intensity of C-C groups and increase in relative absorption intensity of C–O and C = O groups suggesting increasing hydrophilicity.
