Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for quickly and accurately assessing interactions between biological agents such as cells, viruses, and antibodies are inefficient, particularly in identifying effective drugs or antidotes, as they often require numerous experiments and struggle with real-time monitoring of interactions, which can be time-consuming and impractical for rapid virus or toxin response scenarios.
Innovation Solution
A high-throughput method and system for monitoring biological interactions using a platform with multiple interaction sites that support long-term cell culture, controlled fluid delivery, and real-time monitoring, allowing for the detection of changes in biological entities like virus replication or antibody effectiveness through integrated or separate detection means, including interferometry and biochemical assays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional specific time point testing is performed to assess biological interactions, then the experimental process is simple to carry out, but it fails to capture critical interactions between biological agents over real time
Solution Approach 1:
The patent implements continuous real-time monitoring of biological interactions using automated imaging and analysis systems. Instead of discrete time-point measurements, the system continuously captures and analyzes cellular responses to biological agents, ensuring critical interactions are captured as they occur without manual intervention at each time point.
Solution Approach 2:
The patent replaces manual experimental operations with automated computational image analysis and machine learning algorithms. The system automatically processes images, identifies cellular changes, and determines critical interactions without human intervention, significantly reducing the time required while maintaining or improving measurement accuracy.
2Reliability
If numerous experiments are conducted to screen biological interactions, then comprehensive coverage is achieved, but the time required becomes prohibitive for rapid response scenarios
Solution Approach 1:
The patent implements self-service through automated high-content screening where the system autonomously performs experimental setup, data collection, image processing, and result analysis. The automated pipeline processes multiple samples simultaneously without requiring researcher intervention for each experiment, enabling comprehensive screening of numerous biological agents while maintaining high productivity.
Solution Approach 2:
The patent adds temporal dimension to the screening process by performing continuous real-time monitoring across multiple time points within a single experimental run. This allows comprehensive assessment of dynamic biological interactions without requiring separate experiments for each time point, effectively increasing throughput by utilizing the time dimension efficiently.
3Measurement precision
If multiple antibodies are tested against a virus to identify effective ones, then specific effective agents are identified, but the time required for screening increases with the number of combinations
Solution Approach 1:
The patent segments the antibody screening process into parallel independent assay channels, each testing multiple antibodies simultaneously against viral targets. The high-content imaging system divides the screening task across multiple fields of view and time points, allowing comprehensive evaluation of numerous antibody-virus combinations to occur in parallel rather than sequentially, thereby reducing total screening time while maintaining identification accuracy.
4Quantity of substance
If viruses are propagated through cell infection to produce large quantities, then sufficient viral particles are obtained, but the process requires finding suitable host cells which adds time and complexity
Solution Approach 1:
The patent develops universal host cell lines with engineered receptors that can be infected by multiple different virus types. These universal cells express broadly reactive cell surface receptors allowing diverse viruses to attach and enter, eliminating the need to identify and test specific host cell matches for each virus. This multi-functional cell platform enables rapid virus propagation across different viral strains without adding complexity to the cell-virus matching process.

AI summary
A method for identifying an interaction between a pathogen and a biological agent includes providing a platform for supporting cell growth, seeding different interaction sites on the platform with different biological agents, perfusing the platform with a fluid that carries substances for promoting growth and maintenance of the cells, exposing all of the interaction sites to a solution containing viruses, and detecting evidence indicative of the interaction, the evidence comprising evidence indicative of a change in structure or composition of a medium at the interaction site. The biological agent includes cells alone or cells with another substance.
