Area of Science:

• Polymer Chemistry
• Materials Science
• Analytical Chemistry

Background:

• Traditional methods for synthesizing molecularly imprinted polymers (MIPs) are time-consuming.
• The miniMIP approach, while improved, still presents limitations in speed and throughput.
• Efficient synthesis and screening of MIPs are crucial for developing selective adsorbents.

Purpose of the Study:

• To develop a novel, rapid technique for synthesizing and testing large numbers of molecularly imprinted polymers (MIPs).
• To shorten the MIP development procedure significantly compared to existing methods.
• To demonstrate the system's performance by creating a combinatorial library of MIPs selective for cimetidine.

Main Methods:

• Polymers synthesized on microfiltration membranes in multiwell filterplates instead of vials.
• Thin polymeric films utilized for accelerated template removal.
• Combinatorial library approach combined with experimental design and response surface modeling for optimization.

Main Results:

• MIP synthesis and testing time significantly reduced compared to the miniMIP approach.
• MIP development procedure shortened to two days.
• Optimized polymer composition achieved using MAA/EDMA/template molar ratio of 3.5:19.5:1, yielding the highest imprinting factor.

Conclusions:

• The described technique offers a faster and more efficient alternative for MIP synthesis and screening.
• This method facilitates the rapid development of selective MIPs for various applications.
• The use of microfiltration membranes and multivariate analysis streamlines the MIP optimization process.
