Nanoindentation result obtained from the base of an uncoated polyglycolic acid microneedle. Reduced modulus (Er) and hardness (H) data were obtained from nanoindentation data using Oliver-Pharr analysis.
| Data | Indent 1 | Indent 2 |
|---|---|---|
| Reduced modulus (Er) | 5.61 GPa | 5.43 GPa |
| Hardness (H) | 238.96 MPa | 217.37 MPa |
| Maximum depth | 287.5 nm | 299.1 nm |
