Biological Testing TRIZ Cases
- Molecular Trap for Removing Biotin Interference in Assays
A molecular trap captures free biotin via selective binding agents, preventing false results from high biotin levels in patient samples.
- Biological Sample Measurement Apparatus Self-Diagnosis Controller
Controller checks sensor mounting and measurement component status using reference resistor and open state diagnostics.
- Hair Sample Integrity Testing via Reducing Agents
A rapid integrity testing method uses reducing agents and proteases to assess keratinized structures before analyte quantitation.
- Magnetic Assay Device Bound Unbound Reagent Separation
A magnetic assay device differentiates bound from unbound labeled reagents using time-varying magnetic fields to drive distinct optical signals.
- Sensor Device Heating Element for Uniform Fluid Temperature
A sensor device heating element provides a larger heating effect near the inlet than near the outlet to ensure uniform temperature distribution.
- Extracellular Vesicle Quantification via Cholesterol Assay
Cholesterol analysis quantifies extracellular vesicles by replacing nanoparticle tracking with biochemical assays to resolve throughput bottlenecks.
- One-Step IgG Immunoassay Using Multivalent Bridge Antigen
A one-step immunoassay uses a multivalent bridge antigen to capture and detect specific IgG antibodies without washing steps.
- Blood Sample Analysis Using Axial Light Loss
A particle analyzer uses axial light loss measurements to differentiate hard-to-ghost cells from mature red blood cells in blood samples.
- Liposome Preparation via Freezing-Thawing Cycles
Controlled freezing and thawing cycles enhance membrane stability and scalability, extending shelf life while maintaining baseline stability.
- ITPR1 Autoantibody Detection for Paraneoplastic Neurological Syndrome Diagnosis
Detecting ITPR1-binding autoantibodies resolves diagnostic ambiguity by replacing subjective symptom analysis with objective immunological assays.
- Oxygen Sensor Microporous Electrolyte Silver Ion Migration
Zeolite particulates and a gel barrier block silver ions, extending sensor life beyond four weeks.
- Spin Probe Detection for Oilfield Chemical Monitoring
Spin probes attach to oilfield chemicals to enable precise detection via electron paramagnetic resonance.
- Antigen Detection Reference Zone Normalization
Matching epitopes in a reference zone normalize test signals, compensating for sample concentration and temperature variations to improve measurement precision.
- Contact Structure Body for Biological Sample Measurement
A contact structure body uses a separator and probe to link electrodes to circuits.
- Biolayer Interferometry for Crowded Protein Binding Analysis
A biosensor measures target molecule concentration in crowded solutions using biolayer interferometry.
- Noninvasive Skin Antimicrobial Peptide Measurement via Tape Stripping
Tape stripping extracts antimicrobial peptides from the stratum corneum, enabling objective quantitation of skin defense mechanisms without invasive procedures.
- Fluorescent Aptamer Conjugates for Pathogen Surface Detection
Fluorescent aptamer conjugates detect pathogens on surfaces, resolving the trade-off between high detection specificity and operational efficiency.
- Hematology Linearity Control Composition System
Linearity control composition uses stabilized red blood cells to mono-disperse white blood cell analogs via gentle mixing.
