Biological Testing TRIZ Cases
- Macromolecular Analyte Detection via Segmented Reagent System
Segmenting the reagent population isolates target antibodies from non-specific binders, reducing interference and improving measurement precision.
- Sensor Substrate with Immobilized Sugar Molecule Layer
Chemical bonding of sugar molecules to the sensor substrate surface suppresses specific-binding substance deterioration during washing or drying.
- Platelet Aggregation Assay for Anti-CD40L Clotting Risk
Sedimentation-based platelet aggregation assays identify thromboembolic risks from anti-CD40L antibodies.
- T1R1 Receptor Modulators for Umami Enhancement
T1R1 transmembrane modulators amplify umami signals, reducing sodium and glutamate concentrations while maintaining flavor quality.
- Hematology Analyzer RBC Measurement White Blood Cell Interference
A hematology analyzer identifies a valley between red and white blood cell distribution modes to calculate mean cell volume within the defined region.
- Insoluble Carrier Amplification Reagent Layout for Rapid Diagnostics
Pre-coated insoluble carrier integrates first amplification reagent upstream of test sample to enable immediate capillary-driven detection.
- Microparticle-Based SARS-CoV-2 Neutralizing Antibody Assay
Identifiably labelled microparticles conjugated to viral proteins enable rapid neutralizing antibody detection.
- Acoustic Levitation Rheometer for Biological Samples
Acoustic levitation suspends biological samples to enable non-contact rheological measurements, eliminating sample contamination and boundary condition errors.
- Fluorophore Urine Labeling for Tamper-Proof Sample Authentication
Administer fluorophores to a subject before urination to enable optical detection of the marker, verifying sample origin and preventing substitution.
- Immunoassay Sensitivity via High Salt Buffer Conditions
High salt conditions strengthen drug-antibody interactions to improve assay precision and reduce non-specific binding errors.
- Handheld Multi-Substance Detection Device for Impaired Driving
A handheld detection device acquires breath or saliva samples to identify target substances of abuse using integrated electronic sensors.
