Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solid-phase synthesis methods face limitations in synthesizing long polymer chains of high purity, particularly due to steric hindrance and inefficiencies in conventional solid supports, which restrict the growth of large molecules like peptides and oligonucleotides.
Innovation Solution
The method involves performing solid-phase synthesis directly on the internal surface of a capillary, utilizing the capillary channel as the solid support, which reduces steric hindrance and allows for unencumbered growth of polymers, enabling the synthesis of longer chains with higher yields and purity.

Engineering Contradiction Analysis
1Length of moving object
If conventional solid supports are used for polymer synthesis, then the synthesis process can be performed, but steric hindrance restricts the growth of large molecules and limits the synthesis of long polymer chains
Solution Approach 1:
The patent transitions from conventional three-dimensional solid supports to a two-dimensional surface approach by performing synthesis directly on the internal surface of capillary tubes. This dimensional change eliminates the steric hindrance inherent in bulk solid supports, allowing polymer chains to grow unencumbered along the capillary wall and achieving significantly longer polymer lengths with higher yields and purity.
2Manufacturing precision
If conventional solid-phase synthesis methods are used, then polymer synthesis can be achieved, but the methods result in failure sequences that limit the ability to synthesize long polymer chains of high purity
Solution Approach 1:
The patent extracts the polymerization reaction from the bulk solid support environment and relocates it to the interface between the capillary wall and the monomer solution. This extraction allows the reaction to proceed in a controlled manner at the surface, eliminating the failure sequences associated with conventional solid-phase synthesis and achieving high purity and reliable synthesis of long polymer chains.
3Ease of manufacture
If polymers are synthesized and then attached to capillaries, then the capillary can be used for extraction processes, but the process requires multiple steps and the polymer may not be optimally positioned
Solution Approach 1:
The patent performs the polymer synthesis as a preliminary action directly on the capillary wall before the capillary is used for its intended extraction function. This integrated approach eliminates the need for separate attachment steps, simplifies the overall manufacturing process, and ensures the polymer is optimally positioned on the capillary surface for subsequent extraction applications, thereby improving both ease of manufacture and productivity.
