A Synergistic Nano-Hemostatic Spray: An AI-Driven, Biomimetic Approach for Traumatic Hemorrhage Control

Traumatic hemorrhage, responsible for ~40% of trauma-related deaths, necessitates advanced hemostatic interventions beyond conventional agents limited by invasiveness and inefficacy in non-compressible wounds. The Nano-Hemostatic Spray (NHS) is a novel multimodal nano-fluid comprising mucoadhesive chitosan nanoparticles (50–200 nm), hyper-absorbent exfoliated bentonite nanosheets (5–15 wt%), and coagulation-activating calcium chloride (5 wt%) in a hyaluronic acid-supplemented saline carrier. Biomimetically inspired by mussel adhesion and AI-optimized, NHS forms a "smart barrier" via synergistic mechanisms: electrostatic blood component aggregation, plasma concentration, and cascade activation, hypothesizing ≥50% clotting time reduction (<90 s) versus standards, with full biodegradability and minimal toxicity. This perspective delineates scientific foundations, testable hypotheses (e.g., in vivo hemostasis in porcine models), translational challenges (stability, scalability, cost), and future theranostic extensions, supported by peer-reviewed evidence.
