Summary
Molecularly imprinted polymers (MIPs) adapted for capillary electrochromatography (CEC) offer enhanced separation efficiency. This review covers MIP formats and their broad applications beyond CEC, highlighting stability and cost-effectiveness.
Area of Science:
- Analytical Chemistry
- Polymer Science
Background:
- Molecularly imprinted polymers (MIPs) mimic antibody binding characteristics.
- Early MIP applications in liquid chromatography (LC) faced peak broadening issues.
Purpose of the Study:
