Evaluation of Colorimetric BCA-Based Quantification of Hydrazide Groups on Magnetic Particles
Table 1
Magnetic particles used for the determination of hydrazide groups.
| | Magnetic particles | Functional group | Characteristics |
| | SiMAG (1 μm) | Hydrazide | Positive control | | Carboxyl | Negative control | | Carboxyl + ADH | ADH-functionalized |
| | PHEMA (4.5 μm) | Hydrazide | Positive control | | Carboxyl | Negative control | | Carboxyl + ADH | ADH-functionalized |
| | PGMA (4.5 μm) | Carboxyl | Negative control | | Carboxyl + ADH | ADH-functionalized |
