Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional molecular imprinting is used with highly cross-linked organic polymers, then binding sites are formed, but heterogeneous distribution of binding sites occurs leading to strong dependence of selectivity and binding uptake on sample load
Solution Approach 1:
The invention divides the polymerization process into discrete temporal stages: template binding phase, polymerization phase, and template removal phase. This segmentation allows independent optimization of each phase to achieve uniform binding site distribution while maintaining high binding capacity.
Solution Approach 2:
The template is bound to the monomer mixture before polymerization begins, ensuring that templates are positioned and secured in advance. This preliminary action prevents template displacement during polymerization and ensures uniform distribution of binding sites throughout the polymer matrix.
2Reliability
If template is added to monomer mixture for imprinting, then binding sites are formed, but template occlusion occurs resulting in bleeding and requiring multiple purification steps
Solution Approach 1:
The template is selectively removed from the polymer matrix through a dedicated template removal phase using selective solvents or chemical treatments. This extraction step separates the template from the polymer product, eliminating occlusion issues and simplifying purification while maintaining binding site integrity.
Solution Approach 2:
The template is discarded from the final polymer product through controlled removal, and the process is designed to prevent template recovery requirements. The polymerization and removal steps are optimized to ensure complete template elimination without needing subsequent purification steps, reducing manufacturing complexity.
3Reliability
If multiple MIPs need to be synthesized and screened for optimization, then right MIP is found, but process scalability and cost increase
Solution Approach 1:
The invention creates a universal imprinting protocol that can be applied to multiple different templates using the same core process parameters and material system. This multi-functionality allows parallel synthesis of different MIPs with consistent quality, improving scalability while maintaining selection effectiveness.
Solution Approach 2:
The invention uses an excess of template in the monomer mixture to ensure complete coverage of binding sites, even when optimizing for specific selectivity. This excessive action ensures that sufficient binding sites are formed for each MIP variant, allowing efficient screening of multiple candidates without compromising quality.
