Sentinel DNA-Logic Framework: An Autonomous Dual-Capsule Nanobiological System for Ultra-Precise Cancer Cell Eradication

The Sentinel DNA-Logic Framework introduces a revolutionary autonomous dual-capsule (A+B) nanobiological system with an auxiliary immune-protective injection (C) for ultra-precise cancer cell eradication. This conceptual and in-silico study integrates seven distinct biological parameters across two physically separate 35-40 nm DNA origami nanostructures using a pattern recognition-based fuzzy logic decision algorithm (80-95% match threshold) optimized by XGBoost. Upon activation, the system triggers a three-tier therapeutic cascade: (1) apoptosis via TRAIL, (2) oncogene silencing via CRISPR-Cas9/siRNA, and (3) immunogenic cell death (ICD) with long-term immune memory. Key innovations include limited self-replication (max 100 copies), programmed degradation in healthy tissue, inter-capsule chemotactic signaling via ATP gradients, and PEG-free immune protection. Monte Carlo simulations (Geant4-DNA, 10,000 runs) predict 97.8% specificity and 94.2% sensitivity. The framework incorporates clinically validated biomarkers including the GrimAge epigenetic clock and CRISPR-Cas12a-based mutation detection. This work presents a complete theoretical blueprint with mathematical models, system architecture, safety mechanisms, proposed clinical trial design, and 8-10 year translational roadmap.
