Biological Testing TRIZ Cases
- Benzocyanine Compounds with Sulfonic Acid Groups for Fluorescent Imaging
Benzocyanine compounds modified with sulfonic acid groups prevent aqueous aggregation, improving signal-to-noise ratios in biological imaging.
- Immunochromatographic Device Background Noise Reduction
A colorant in the absorption zone reduces background noise from labeling carriers.
- Lateral Flow Assay Device External Data Integration
A lateral flow assay device connects to public networks to receive external diagnostic information for result augmentation.
- Standardizing Platelet Function Measurement Across PFA Cell Types
Resolves non-standardized closure times by applying normalization formulas that transform raw data into comparable platelet function metrics.
- Cholesterol Measurement Cartridge with Movable Membrane Alignment
A cholesterol measurement cartridge uses movable upper and lower cases to align sample transferring membranes with measuring membranes for direct serum transfer.
- Boron Nitride Nanotube Capsule for Fluorogenic Probe Stability
A boron nitride nanotube capsule encapsulates fluorogenic molecules to create a stable near-infrared fluorescent nanoprobe.
- Cell-Based Reporter Assay for Antibody Potency
Automated reporter gene expression replaces manual bioassays to resolve assay duration and variability trade-offs.
- Partial Lysis Reagent for Malaria Detection
A surfactant reagent partially lyses red blood cell membranes to retain malaria parasites while allowing fluorescent dye penetration.
- Double Antigen Bridging Immunoassay for Anti-Drug Antibody Differentiation
Spiking samples with monomeric and oligomeric drug antibody forms allows the assay to distinguish specific from non-specific anti-drug antibodies.
- Surrogate Antibody Bridging ELISA for Fc-Region Modified Antibodies
A serial bridging ELISA employs a non-therapeutic surrogate antibody to determine Fc-region modified antibodies without cross-reactivity interference.
- Automatic Analyzer Reagent Heating Stability
Feedback control and thermal regulation stabilize reagent temperature against external fluctuations, ensuring accurate coagulation time measurement.
- Whole Blood Thrombin Potential Measurement via Electrical Impedance
A blood coagulation module measures thrombin potential using whole blood electrical properties without plasma extraction.
- Oligomer Sequence Mapping via Key Substitution
A mapping system generates keys from oligomer sequences and modifies them through base substitutions to locate candidate positions in a reference index.
- Biosensor Abnormal Waveform Detection Circuit
A biosensor measurement system uses a second electrode system to detect abnormal waveforms during operation.
- Nucleic Acid Aptamer Binding Elements for Reversible Target Detection
Replacing protein binders with nucleic acid aptamers eliminates immunogenicity while maintaining high selectivity across repeated regeneration cycles.
- Immunoassay Binding Strength Detection via Displacement Kinetics
A displacement assay detects analytes and measures binding strength simultaneously using fluorescence markers on a fixed surface.
- Modular Chemistry Analyzer with RFID Reagent Tracking
A modular chemistry analyzer integrates a unitary base and RFID-tagged vessels for automated test specification management.
- Fluorescent Cell Binding Assay Normalization
A fluorescent cell binding assay uses housekeeping proteins to normalize bound protein signals for accurate quantification.
