In the original publication [1], there was a mistake in reporting certain row values of the “Components” column in Tables 9 and 10. The revised Table 9, with a modified caption “Nominal compositions of SBA2 and SBA3 control bioactive glasses”, and Table 10, with a modified caption “Nominal compositions of the ST control bioactive glass and ST after ion doping”, appear below. The column name “Components” is replaced by “mol.%” (mole fractions). Moreover, Table 9 and Table 10 were re-arranged horizontally.
Table 9.
Nominal compositions of SBA2 and SBA3 control bioactive glasses.
Table 10.
Nominal compositions of the ST control bioactive glass and ST after ion doping.
The following correction has been made to Section 4. Materials and Methods, 4.1. Bioactive Glasses Preparation:
In the present study, silica-based bioactive glasses, either doped on their surface with silver- or copper-ions via ion exchange or by including tellurium oxide directly to the glass as a substitute for silica, were prepared following the descriptions in [93–95]. The compositions of SBA2 and SBA3 (undoped controls) are shown in Table 9.
Both SBA2 and SBA3 were prepared using a melting and quenching process. In short, all the components listed above were melted in a platinum crucible at 1450 °C for 1 h, after which the melt was cooled in a brass mold to obtain glass bars with a diameter of 1 cm, which were then annealed at 500 °C for 13 h and cut into discs of 2 mm thickness. The discs were polished with SiC abrasive papers up to 1200 grit to level the surfaces. For the ion-doping procedure, silver (Ag+) and copper (Cu2+) ions were incorporated onto the surface of SBA2 and SBA3, respectively, through the ion-exchange process consisting of submerging them in an aqueous solution of AgNO3 (0.03 M) or Cu(CH3COO)2 (0.001 M) for 1 h, at 37 °C.
Additionally, the composition of ST with 5% molar tellurium or without (in previous works denominated as Ste0 or a doped version of STe5, [94]) is described in Table 10.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
