Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to develop methods for manufacturing jellyfish collagen hydrogels that are stable at physiological temperatures, as existing methods struggle due to the low thermostability of jellyfish collagen, which limits its use in cell culture and medical applications.
Innovation Solution
A process involving the mixing of purified jellyfish collagen with an aqueous neutralization buffer, followed by incubation to form collagen fibrils, with the option to add a cross-linking agent, results in thermally and mechanically responsive jellyfish collagen hydrogels stable between 25° C. and 50° C.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If jellyfish collagen is used to form hydrogels, then manufacturing cost is reduced and virus transmission risk is eliminated, but the hydrogels lack stability at physiological temperatures
Solution Approach 1:
The patent applies parameter changes by modifying the chemical composition parameters of the hydrogel system. Specifically, it introduces cross-linking agents (genipin, EDC, or glutaraldehyde) at controlled concentrations and adjusts pH levels during fabrication. These parameter modifications transform the thermally unstable jellyfish collagen into a stable hydrogel structure that maintains integrity at physiological temperatures, directly resolving the thermostability limitation while preserving the biological safety advantages of jellyfish collagen.
Solution Approach 2:
The patent creates composite materials by combining jellyfish collagen with cross-linking agents to form a new material system with enhanced properties. The cross-linked jellyfish collagen hydrogel integrates the biocompatibility and low cost of jellyfish collagen with the thermal stability provided by the cross-linking network, producing a composite material that overcomes the inherent thermostability weakness of pure jellyfish collagen.
2Reliability
If cross-linking agents are added to improve hydrogel stability, then thermal stability increases, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-mixing the cross-linking agent with the jellyfish collagen solution before hydrogel formation, or by having cross-linking agents ready in solution form. This preliminary preparation simplifies the manufacturing process by eliminating the need for separate cross-linking steps and allowing hydrogel formation to occur in a single incubation step, thereby reducing manufacturing complexity while achieving the desired thermal stability.
