(A) Generated radicals in silver ion solution with and without bacterial suspension and purple LED irradiation. *Significant differences (p < 0.05). (B) Radicals generated in silver ion solution with and without biofilms on titanium disks, under purple LED irradiation. *Significant difference (p < 0.05). + indicates application or irradiation. (C) Representative electron spin resistance (ESR) spectra of the radicals generated by the following treatments: (a) bacterial suspension(−) silver application(+) Purple-LED irradiation(−), (b) bacterial suspension(−) silver application(+) Purple-LED irradiation(+), (c) bacterial suspension(+) silver application(+) Purple-LED irradiation(−), and (d) bacterial suspension(+) silver application(+) Purple-LED irradiation(+). (D) Representative ESR spectra of the radical generated by the following treatments: (a) Titanium with biofilm(−) silver application(+) Purple-LED irradiation(−), (b) Titanium with biofilm(−) silver application(+) Purple-LED irradiation(+), (c) Titanium with biofilm(+) silver application(+) Purple-LED irradiation(−), and (d) Titanium with biofilm(+) silver application(+) Purple-LED irradiation(+).
