Autonomously Nourishing Embryos for ETF Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting embryotoxic factors (ETFs) are costly, time-consuming, and lack operational flexibility, and the use of animal models raises ethical concerns, limiting their feasibility and scalability.
Innovation Solution
A method using autonomously nourishing living organisms, such as zebrafish or medaka fish embryos, which are not considered animals under regulatory definitions until they exhaust their yolk sac nutrients, allowing for large-scale, reliable testing of samples for ETFs without the need for expensive animal models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If animal models (mouse embryos) are used for detecting ETFs, then the reliability of detection is improved, but the operating costs increase and ethical concerns arise
Solution Approach 1:
The patent uses zebrafish embryos as a simplified model that copies the essential biological functions needed for ETF detection without requiring the complex infrastructure and ethical approvals associated with mouse models. The zebrafish embryo serves as a surrogate system that maintains detection reliability while reducing operational complexity and cost
Solution Approach 2:
Zebrafish embryos are used as a cost-effective alternative to mouse embryos. They are inexpensive to produce, require minimal care, and can be disposed of after use, eliminating the need for expensive animal facility maintenance and complex ethical compliance procedures while maintaining adequate detection reliability
2Measurement precision
If mouse embryos are used for testing, then detection accuracy is improved, but the time required for the test increases
Solution Approach 1:
The patent changes the biological model parameter from mouse embryos to zebrafish embryos, which have faster development cycles. This parameter change maintains the essential embryonic characteristics needed for accurate ETF detection while reducing the incubation time required from several days to approximately 72 hours, thereby improving test execution speed without sacrificing detection accuracy
3Reliability
If animal models are used, then the biological response to ETFs is accurately captured, but regulatory restrictions and ethical limitations increase
Solution Approach 1:
The zebrafish embryo serves as a surrogate copying the essential biological responses to ETFs without triggering the same regulatory and ethical constraints as mouse models. This allows the system to maintain biological response accuracy while operating in a more flexible regulatory environment that does not require the same level of ethical approval and institutional oversight

AI summary
A method for detecting chemical substances in samples of material that can be taken from a subject, comprising a step of preparing a sample of a substance coming from a donor organism; a step of associating with said sample of a substance a control element suitable for verifying a presence of at least one active agent in the sample of the substance and a step of verifying the presence or absence of the active agent based on a change in state in said control element; the control element comprising at least one living organism having the ability to nourish itself autonomously through temporary organs associated with the living organism itself and able to supply nutritive substances to the latter without taking said nutritive substances from an outside environment.
