Molecularly imprinted polymers: synthetic receptors in bioanalysis

Area of Science:

• Materials Science
• Analytical Chemistry
• Biochemistry

Background:

• Molecularly imprinted polymers (MIPs) are synthetic materials with tailored cavities for specific molecular recognition.
• MIPs exhibit high affinity and selectivity, analogous to biological receptors, earning them the name 'synthetic receptors' or 'plastic antibodies'.
• Their application in affinity separations, particularly solid-phase extraction (SPE), is a growing area of research.

Purpose of the Study:

• To review the potential and recent advancements of MIPs in affinity separation techniques.
• To emphasize the application of MIPs in solid-phase extraction (SPE) for isolating analytes from complex matrices.
• To discuss challenges and solutions for using MIPs in aqueous environments for SPE.

Main Methods:

• Review of existing literature on molecularly imprinted polymers (MIPs).
• Focus on MIPs utilized in solid-phase extraction (SPE) methodologies.
• Analysis of research aimed at developing water-compatible MIPs for aqueous applications.

Main Results:

• MIPs demonstrate significant potential for selective analyte extraction in complex samples.
• Development of water-compatible MIPs enhances their applicability in diverse, including aqueous, environments.
• Strategies to overcome challenges in MIP-based SPE have improved their efficiency and reliability.

Conclusions:
