Unknown Materials TRIZ Cases
- Probiotic B12 Production via Propionibacterium freudenreichii
Propionibacterium freudenreichii bacteria produce vitamin B12 in the gut, addressing insufficient supplementation for vegetarian and pregnant populations.
- Highly Refined Cellulose Prebiotic Delivery System
Highly refined cellulose protects probiotics from stomach acid while thickening fluids to assist dysphagia patients.
- Perforated Tissue Matrix with Patterned Holes
Patterned perforations improve fluid drainage and suture retention while maintaining tensile strength through local quality and parameter changes.
- Enteric Coated Solid Dosage Forms for Bacteria and mEVs
Varying enteric coating thickness controls intestinal release timing, resolving the trade-off between gastric protection and precise delivery site.
- Pulmonary Ligament Tissue Fixation for Stent Scaffolds
Controlled glutaraldehyde fixation of pulmonary ligament tissue maintains elasticity and biological properties lost in conventional scaffolds.
- Alginate-ECM Microcapsules for Islet Viability
Alginate microcapsules incorporate extracellular matrix proteins to enhance pancreatic islet cell adhesion and insulin secretion.
- Alginate Microparticle Encapsulation via Coaxial Spray-Drying
Coaxial spray-drying crosslinks alginate around live microorganisms, maintaining viability during high-speed production.
- Ex Vivo Perfusion for Donor Organ Gene Therapy
Circulating viral vectors through donor organs during ex vivo perfusion to achieve robust transgene expression before transplantation.
- Image-Guided Cell Generation Protocol for Yield Optimization
A computerized image analysis system dynamically monitors cell generation steps to determine readiness and guide remedial actions.
- Elastase-Treated Arterial Tissue Hydrogel for Biocompatibility
Acellular arterial tissue matrix treated with elastase forms a hydrogel scaffold.
- Birnavirus Oncolytic Therapy for Cancer Stem Cell Resistance
Birnaviruses overcome cancer stem cell resistance by inducing immunogenic cell death and activating interferon signaling pathways.
- Cytolytic CD4+ T Cell Isolation via Phenotypic Segmentation
Segmenting CD4+ T cell populations by Foxp3 status isolates cytolytic subsets, resolving low frequency and non-specific activity in adoptive transfer.
- pH-Dependent Microencapsulation for Ileum Probiotic Delivery
Segmented microcapsules protect probiotics from stomach acid, releasing them in the ileum to treat Clostridium difficile infection.
- Dry Food Composition Particle Size Distribution for Nutrient Balance
A dry food composition uses ball mill grinding to optimize particle size distribution for smooth texture and high nutrient bioavailability.
- Human Kidney-Derived Cells for Diabetic Nephropathy Repair
Scaffold-seeded human kidney-derived cells delay end-stage renal failure onset by reducing protein excretion rates and halting disease progression.
- Dual VEGFR-3 and VLA-1 Antagonist Therapy for Corneal Transplant Rejection
Dual receptor blockade reduces inflammatory lymphangiogenesis to enhance corneal graft survival.
