Polymeric Gel Carriers for Low-Damage Tissue Section Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring biological specimens, such as tissue sections, often cause damage due to strong contact forces, making it difficult to move them from one surface to another without causing harm.
Innovation Solution
A carrier substrate, such as a hydrophilic or hydrophobic polymeric gel, is used to immobilize and transfer tissue sections by maintaining a hydrated interfacial surface, allowing for gentle handling and transfer onto receiving substrates like glass or plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional transfer methods are used to move tissue sections between surfaces, then transfer capability is achieved, but sample damage occurs due to strong contact forces
Solution Approach 1:
The patent introduces a water bath as an intermediary medium between the tissue section and the receiving surface. The tissue section is first transferred to the water bath, which reduces direct contact forces, and then from the water bath to the final surface. This intermediary step significantly reduces mechanical damage to the fragile tissue section during transfer operations.
2Reliability
If tissue sections are attached to glass slides for examination, then analysis capability is improved, but subsequent transfer becomes difficult without damage due to strong adhesion forces
Solution Approach 1:
The patent applies preliminary coating of the glass slide and/or tissue section with a transfer facilitation coating before attachment. This coating is specifically designed to reduce adhesion strength, allowing the tissue section to be easily detached and transferred to subsequent surfaces while maintaining proper attachment for initial analysis. The coating is applied in advance to prevent permanent bonding.
3Adaptability or versatility
If multiple transfers are performed on tissue sections, then comprehensive analysis is enabled, but cumulative damage increases with each transfer
Solution Approach 1:
The patent uses the water bath as a reusable intermediary medium that can facilitate multiple transfers without degrading. Each transfer goes through the water bath, which consistently reduces contact forces. This enables comprehensive multi-step analysis while maintaining sample integrity, as the water bath intermediary protects the tissue section from cumulative mechanical damage across multiple transfer operations.
