Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating substance permeability through central nervous system (CNS) tissues are invasive, limited in their consideration of sophisticated biological mechanisms, and difficult to use for simultaneous screening of multiple target substances, leading to restricted information and reproducibility issues.
Innovation Solution
A novel evaluation probe, represented by a specific dye compound formula, is used to assess CNS permeability by permeating into biological specimens and serving as a substrate for transporters, allowing for functional evaluation and screening of compounds influencing transporter action in a less-invasive manner, considering in vivo metabolism mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive methods are used to evaluate CNS permeability, then measurement precision is improved, but ease of operation deteriorates and reliability worsens due to reproducibility issues
Solution Approach 1:
The patent introduces an evaluation probe as an intermediary substance that mediates between the testing system and the CNS tissue. This probe serves as a model substrate that interacts with transporters without requiring invasive procedures, thereby maintaining measurement precision while improving ease of operation and reliability through non-invasive evaluation methods
2Measurement precision
If existing screening methods are used, then measurement precision is improved, but productivity deteriorates due to inability to screen multiple substances simultaneously
Solution Approach 1:
The evaluation probe is designed with multi-functionality to serve as a universal tool for screening multiple substances and evaluating various transporter functions simultaneously. The probe can be used across different experimental conditions and substance types, enabling high-throughput screening while maintaining measurement precision through its standardized interaction mechanism with transporters
3Reliability
If sophisticated biological mechanisms are fully considered, then reliability is improved, but device complexity worsens
Solution Approach 1:
The evaluation probe system utilizes the biological specimen's own sophisticated mechanisms (such as in vivo metabolism and transporter functions) to perform the evaluation automatically. The probe interacts with the specimen's endogenous transporters and metabolic pathways, allowing the biological system itself to serve the evaluation function without requiring complex external experimental apparatus, thereby improving reliability while minimizing added complexity
