Molecularly Imprinted Polymer-Silica Hybrid Particles for Biomimetic Recognition of Target Drugs

Figure 3

(a) The decreasing absorbance of amlodipine on successive washings confirms the removal of template molecules from the MIP-silica hybrid particles, whereas (b) shows the absorbance of standard amlodipine solutions (concentration: 10-80 ppm) decreasing after treatment with the hybrid particles.
