Molecularly imprinted polymers (MIPs) offer a cost-effective and stable alternative to antibodies for selective solid-phase extraction. This review details their synthesis and application in isolating analytes from complex samples.

Area of Science:

  • Polymer Chemistry
  • Analytical Chemistry
  • Separation Science

Background:

  • Molecularly imprinted polymers (MIPs) are synthetic materials with tailored cavities for specific molecular recognition.
  • They function as selective sorbents in solid-phase extraction (SPE), analogous to antibodies but with enhanced stability and ease of preparation.
  • MIPs offer advantages over traditional methods, including cost-effectiveness, rapid synthesis, and robustness in diverse chemical environments.

Purpose of the Study:

  • To review the application of MIPs in solid-phase extraction for selective analyte isolation.
  • To discuss the synthesis of MIPs and factors influencing extraction selectivity.
  • To highlight the potential of MIPs in complex sample matrices, LC coupling, and miniaturized analytical devices.
