Biological Testing TRIZ Cases
- Configurable Wash Process for Sample Analyzer Reaction Cells
A configurable washing arrangement uses timed sequences of wash actions to remove unreacted components from reaction cells.
- Bio-MEMS Transducer with Piezoelectric Microcantilever for Muscle Stress Measurement
A bio-MEMS transducer couples a cultured myotube to a piezoelectric microcantilever to detect contraction forces via electrical signal generation.
- Site-Specific Mutation for L-Threonine Overproduction
Site-specific gene disruption and strong promoter introduction in mutant microorganisms increase L-threonine yield while maintaining growth rate.
- Metal-Bis(dipicolylamine) Ligands for Microvesicle Capture
Metal(II)-bis(dipicolylamine) ligands capture phosphatidylserine-enriched microvesicles to resolve detection accuracy and diagnostic reliability trade-offs.
- Immunochromatography Diluent for Infant Fecal Sample Analysis
Dicarboxylic and tricarboxylic acids in the diluent suppress fecal interference, enabling accurate analyte detection in infant samples.
- Parallel Control Preparation for Signal Discrimination in Detection Methods
Parallel control preparations subtract non-specific background noise to improve measurement precision and diagnostic reliability.
- Combinatorial Barcoding for Low-Abundance Protein Identification
Split-pool barcoding generates unique nucleic acid tags from amino acid residues, enabling detection of low-abundance proteins in complex mixtures.
- Predicting Misfolded Protein Epitopes via Collective Coordinate Bias
A conformational sampling engine applies global collective coordinate bias to force protein unfolding for epitope identification.
- Probe Delivery of Membrane Proteins to Lipid Bilayers
A probe delivers membrane proteins directly onto a lipid bilayer using a carrier surface for rapid insertion.
- Dispensing Mechanism for Test Strips Using Unidirectional Spring Rotation
A dispensing mechanism uses a spring with an engagement section to move measurement strips out of a cartridge slot.
- Dielectric Microsensor for Hemostatic Dysfunction Assessment
A dielectric microsensor measures blood permittivity changes to assess hemostatic dysfunction.
- Multi-Receptor Assay for Analyte Detection
Multiple receptors bind distinct epitopic sites to reduce cross-reactivity and improve detection accuracy in small samples.
- Monoclonal Antibody for Active Renin Immunoassay
A monoclonal antibody detects active renin concentration through specific immunological recognition of conformational epitopes.
- Haptoglobin Glycan Analysis for Hepatocellular Carcinoma Detection
Analyzing specific haptoglobin glycan structures detects hepatocellular carcinoma, overcoming the low sensitivity of AFP biomarkers.
- Fluorescent Polymer Dyes with Charged Linkers
Charged linkers enforce spatial separation between fluorescent moieties, reducing intramolecular quenching and increasing molar brightness.
- Ex Vivo Human Skin Model for Allergic Inflammation Prediction
An ex vivo human skin model assesses inflammatory potential by measuring mast cell degranulation and granulocyte behavior.
