TSST-1 Toxin Detection Device Using Antibody Complexes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tests for toxic shock syndrome (TSS) take hours or days to produce results, allowing the condition to progress and cause irreversible damage before diagnosis, as they focus on detecting Staph bacteria rather than the specific toxins responsible for TSS.
Innovation Solution
A device comprising a pad and membrane with specific antibodies configured to react with toxic shock syndrome toxin one (TSST-1) antigens, providing rapid and accurate detection of TSS toxins through visible or quantifiable indications, allowing for in-situ testing without the need for laboratory analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional blood tests are used to detect TSS, then the test can detect Staph bacteria, but the test results take hours or days which allows TSS to progress and cause irreversible damage
Solution Approach 1:
The invention extracts and detects only the specific TSST-1 toxin antigen that causes TSS, rather than detecting all Staph bacteria. This extraction of the critical pathogen element enables rapid specific detection in minutes while maintaining high accuracy for TSS diagnosis.
Solution Approach 2:
The invention changes the detection parameter from general bacterial presence to specific toxin antigen concentration. By using immunological reactions between antibodies and TSST-1 antigens, the test achieves both rapid results (parameter change from hours/days to minutes) and high specificity for TSS detection.
2Reliability
If conventional tests detect Staph bacteria, then they can identify potential TSS risk, but they produce false positives because not all Staph bacteria produce TSS toxins
Solution Approach 1:
The invention extracts detection from general bacterial detection to specific toxin detection. By targeting only TSST-1 antigens with specific antibodies, the test eliminates false positives from non-toxigenic Staph bacteria while maintaining high reliability for actual TSS cases.
Solution Approach 2:
The invention applies local quality by using different antibodies with specific binding affinities for TSST-1 antigens. The first antibody captures TSST-1 specifically, while the second antibody detects the complex, creating a localized specific detection system that distinguishes TSS-causing bacteria from other Staph strains.
3Loss of time
If rapid detection of TSS toxins is implemented, then timely intervention is enabled, but the device complexity increases compared to conventional blood tests
Solution Approach 1:
The rapid detection device is self-service in that it performs all detection functions in a single integrated unit without requiring external laboratory equipment. The immunological reactions, color development, and result interpretation all occur within the device itself, enabling point-of-care testing in minutes.
Solution Approach 2:
The invention uses color changes as a simple visual indicator of TSST-1 detection. When antibodies bind to TSST-1 antigens, a colorimetric reaction occurs that can be read directly on the device, eliminating the need for complex instrumentation while achieving rapid results.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enables quick and accurate detection of TSS toxins, reducing false positives and providing results in minutes, compared to hours or days for conventional tests, by directly detecting TSST-1 antigens rather than Staph bacteria, facilitating timely intervention.
Implementation Method 1

AI summary
A device for detecting toxic shock syndrome toxins includes a pad and a membrane coupled to the pad. The pad includes first antibodies that include a first particular antibody and a second particular antibody. Each of the first antibodies are associated with toxic shock syndrome toxin one (TSST-1). The first particular antibody is configured to react with a TSST-1 antigen to form an antibody complex. The membrane includes a first zone that includes an immobilized second antibody configured to react with the antibody complex to cause a first indication. The membrane further includes a second zone that includes a third antibody configured to react with the second particular antibody to cause a second indication.
