A Corrigendum on
Core-Shell 3D printed biodegradable calcium phosphate cement – Alginate scaffolds for possible bone regeneration applications
by Schweiker C, Zankovic S, Baghnavi A, Velten D, Schmal H, Thomann R and Seidenstuecker M (2024). Front. Drug Deliv. 4:1407304. doi: 10.3389/fddev.2024.1407304
In the published article, there was an error in Table 1 as published. An X was incorrectly placed at GP4 for PBS 1 week. The corrected Table 1 and its caption Table 1: Classification of the groups according to post treatment appear below.
Table 1
Table 1. Classification of the groups according to post treatment.
In the published article, there was an error. In several instances, GP4 was incorrectly used instead of GP3.
A correction has been made to Results, 3.2.1 Mechanical properties, Paragraph 1. This sentence previously stated:
“It can be observed that the samples in GP1 (reference) and GP4 (freeze-dried) exhibit significantly lower maximum values.”
The corrected sentence appears below:
“It can be observed that the samples in GP1 (reference) and GP3 (freeze-dried) exhibit significantly lower maximum values.”
A correction has been made to Results, 3.2.1 Mechanical properties, Paragraph 2. This sentence previously stated:
“The non-post-treated sample GP1 showed a 4-fold higher mechanical strength compared to the GP4 freeze-dried sample, which also had no (self) setting/crosslinking time.”
The corrected sentence appears below:
“The non-post-treated sample GP1 showed a 4-fold higher mechanical strength compared to the GP3 freeze-dried sample, which also had no (self) setting/crosslinking time”
A correction has been made to Discusson, 4.3 Mechanical properties, Paragraph 1. This sentence previously stated:
“The reason for the low strength of sample GP4 is that this sample was frozen directly after printing to prevent the (self) setting/crosslinking reaction and to be able to compare it with the other samples.”
The corrected sentence appears below:
“The reason for the low strength of sample GP3 is that this sample was frozen directly after printing to prevent the (self) setting/crosslinking reaction and to be able to compare it with the other samples.”
In the published article, there was an error. Group 12 was incorrectly used instead of Group 8.
A correction has been made to Discusson, 4.2 Surface condition. This sentence previously stated:
“Samples from group 12-1 show no signs of alginate coating in the SEM, as the solution is too thin to be detected in the ESEM. Group 12-2 and 12-3, on the other hand, both show an alginate coating, albeit unevenly.”
The corrected sentence appears below:
“Samples from group 8-1 show no signs of alginate coating in the SEM, as the solution is too thin to be detected in the ESEM. Group 8-2 and 8-3, on the other hand, both show an alginate coating, albeit unevenly.”
The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.
