Dual-Component Biosensor for Detecting Mutated COVID Strains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diagnostic methods for COVID-19, particularly against mutated variants like Omicron, are ineffective due to rapid viral mutations, leading to a need for timely and comprehensive detection systems that can identify new SARS-CoV-2 virus strains in human sputum and saliva samples.
Innovation Solution
A biosensor system utilizing two different biological components, separated by a membrane, interacts with sputum and saliva samples to generate electrical, magnetic, or optical signals, which are processed by a memory device and wireless communication system to identify specific SARS-CoV-2 virus strains, incorporating microfluidic chips and graphene coatings for selective molecule interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional diagnostic methods and vaccines are used, then they may be effective against original SARS-CoV-2 strain, but they become ineffective against mutated variants such as Omicron
Solution Approach 1:
The biosensor system is designed with multiple biological components (proteins, antibodies, enzymes, DNA/RNA molecules) that can detect various SARS-CoV-2 variants simultaneously. The system performs multiple functions: detecting original strain, identifying mutated variants, and providing comprehensive diagnostic information, making it universally applicable across different virus strains without requiring separate diagnostic tools for each variant.
Solution Approach 2:
The system detects mutations by identifying changes in viral genetic parameters (RNA sequences, protein structures). By monitoring parameter changes in the virus genome and comparing them against known variant profiles, the biosensor can distinguish between original and mutated strains, adapting to new variants as they emerge through systematic parameter analysis rather than requiring complete redesign.
2Reliability
If lockdown measures are implemented to control virus spread, then virus transmission is reduced, but economy cannot function normally for extended periods
Solution Approach 1:
The portable biosensor system enables individuals to perform self-testing at home using saliva or sputum samples, eliminating the need for centralized laboratory testing and extensive lockdown measures. This self-service capability allows continuous economic activity while maintaining virus detection and control, as people can independently monitor their health status without requiring shutdown of businesses or restriction of movement.
Solution Approach 2:
The patent replaces mechanical lockdown measures (physical restrictions, closures) with a technological solution (portable biosensor system). Instead of using forceful mechanical control through lockdowns, the system uses biological detection mechanisms to monitor and control virus spread, allowing economic activities to continue normally while maintaining public health safety through widespread individual testing.
3Reliability
If comprehensive vaccine distribution is implemented to protect against all variants, then population immunity is improved, but vaccine quantities and distribution logistics become insufficient
Solution Approach 1:
The biosensor system extracts the diagnostic function from vaccine dependency. Instead of relying solely on vaccines for protection, the system extracts viral detection capability directly into a portable device that can identify infections in real-time. This reduces the burden on vaccine distribution systems by providing an alternative protective mechanism through early detection and isolation of cases, complementing rather than replacing vaccination efforts.

AI summary
Systems for determining COVID include a biosensor that interacts with a sputum sample and outputs the first and second signals; a wireless communication device; a memory device with detectors embedded in the memory device. The biosensor is configured to use two different biological components with the first and second biological components separated by a membrane. The concentration of the first biological component corresponds to the threshold for the first virus strain and the concentration of the second biological component corresponds to the threshold for the second virus strain. The memory device is configured to receive the first and second signals and set the first and second signal thresholds for each detector. The memory device identifies the presence of the first or second virus strain in response to detectors embedded in the memory device are detecting a value that is greater than or less than the first or second signal threshold.
