Evaluation of Colorimetric BCA-Based Quantification of Hydrazide Groups on Magnetic Particles

Figure 3

The comparison of two methods for the determination of hydrazide groups. TNBS (dark columns) and BCA-based (light columns) tests on three carboxyl-containing MPs functionalized with ADH. (a) SiMAG, (b) PHEMA, and (c) PGMA. Particles with carboxyl groups served as negative controls, and those with hydrazide groups as positive controls.
