Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for sequence-controlled synthesis of non-biological polymers are limited by premature termination and poor synthetic yields, lacking in situ monitoring of synthetic efficiency and structural characteristics.
Innovation Solution
The development of monomer units with removable blocking groups and fluorescent labels allows for optical verification of each monomeric addition during polymer chain synthesis, using methods such as Suzuki-Miyaura cross-coupling and DNA-templated oligomer synthesis, enabling sequence-specific polymer chain assembly with in situ monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequence-controlled synthesis of non-biological polymers is performed using conventional methods, then polymer chains can be synthesized, but premature termination occurs and synthetic yields are poor
Solution Approach 1:
The patent implements real-time optical monitoring of polymer chain synthesis by incorporating fluorescent labels that emit signals when monomers are successfully added. This feedback mechanism allows detection of premature termination events and enables corrective actions, thereby improving both synthetic yield and reliability by ensuring complete chain extension.
Solution Approach 2:
The patent replaces conventional analytical methods with optical detection systems. Fluorescent labels and optical sensors substitute traditional mechanical or chemical analysis techniques, enabling non-invasive, real-time monitoring of synthesis progress without disrupting the chemical reactions, thus improving yield and reducing termination.
2Loss of information
If conventional polymer synthesis methods are used, then polymer chains can be formed, but in situ monitoring of synthetic efficiency and structural characteristics is not possible
Solution Approach 1:
The patent utilizes fluorescent labels that undergo color changes or emit light at specific wavelengths when monomers are incorporated into the polymer chain. This optical signal provides real-time information about synthetic efficiency and structural characteristics, enabling in situ monitoring without complex additional equipment.
Solution Approach 2:
The patent introduces fluorescent labels as intermediary molecules that bridge the synthesis process and detection system. These labels attach to monomers and provide optical signals that carry information about synthesis progress, enabling monitoring while adding minimal complexity to the overall system.
3Measurement precision
If fluorescent labels are incorporated for optical verification, then each monomeric addition can be verified, but the complexity of monomer units increases
Solution Approach 1:
The patent extracts the detection function from the main polymer chain by using separate fluorescent labels that attach to monomers. This separation allows precise verification of monomeric addition while keeping the core polymer structure simple, as the fluorescent components can be removed or are minimal in quantity.
Solution Approach 2:
The patent applies fluorescent labels only at specific locations (on individual monomer units) rather than throughout the entire polymer structure. This localized approach provides precise measurement capability at the monomer level while minimizing overall structural complexity and maintaining simple polymer backbone architecture.
