Our Solution
NeuroShield is a proposed neurodefense system designed to identify early signals associated with viral neuroinvasion risk and respond before significant neurological damage occurs. By combining a handheld biosurveillance scanner, an AI-driven algorithm to calculate the Neuroinvasion Risk Index, and targeted nanocarrier-based defense strategies, NeuroShield focuses on the earliest stages of viral brain entry rather than reacting only after infection has progressed.
Biosurveillance and Risk Analysis
NeuroShield begins with early detection through a handheld biosurveillance scanner designed to collect biological signals associated with neuroinvasion risk. The handheld biosurveillance scanner uses non-invasive biosensing techniques to detect biological indicators in blood or tissue, including viral load, inflammation, receptor-related risk, and blood-brain barrier stress, which are then processed by the algorithm.
These signals are continuously gathered and prepared as inputs for the algorithm to calculate the Neuroinvasion Risk Index. By capturing early-stage biological changes before neurological symptoms appear, the biosurveillance system enables real-time monitoring and forms the foundation for data-driven risk analysis.
NRI Algorithm
The AI-driven algorithm processes the biological signals collected by the biosurveillance system and calculates the Neuroinvasion Risk Index (NRI). Using inputs such as viral load, inflammation, receptor susceptibility, and blood-brain barrier stress, the algorithm generates the NRI, a single risk score that reflects the likelihood of viral entry into the brain.
In addition to calculating overall risk, the algorithm identifies the primary factors driving that risk and detects patterns that may indicate early neuroinvasion. When the calculated score exceeds a defined threshold, the NRI determines that intervention is necessary and activates the targeted defense system.
Defense at the Blood-Brain Barrier
When the NRI reaches a critical threshold, NeuroShield initiates a targeted nanocarrier-based response strategy. NeuroShield’s response focuses on three protective mechanisms.
1: Barrier Support
Supportive strategies help maintain the stability of the blood-brain barrier during periods of elevated risk, strengthening protection at the point where intervention is most needed.
2: Receptor Blocking
Engineered nanobodies are designed to temporarily interfere with viral entry pathways, including those associated with receptors such as Neuropilin-1.
3: Decoy Particles
Synthetic decoy particles are designed to bind to viral particles, redirecting them away from native cells and reducing the likelihood of successful entry.
Prototype and System Model
NeuroShield begins with early detection through a handheld biosurveillance scanner and feeds data into the NRI algorithm. Once activated, NeuroShield initiates a targeted response at the earliest stages of viral entry. Targeted nanocarriers deliver engineered nanobodies and decoy particles through the bloodstream to high-risk regions near the blood-brain barrier. At the barrier, nanobodies interfere with viral entry pathways, decoy particles bind to viral particles, and supportive strategies help maintain barrier stability. These responses are guided by the NRI to reduce the likelihood of viral entry into the brain.
Why NeuroShield Matters
NeuroShield addresses a stage of infection that current treatments often miss: the period before viral entry into the brain has fully occurred. By focusing on early warning signals, targeted response, and protection at the blood-brain barrier, NeuroShield is designed to improve the likelihood of earlier intervention and better neurological outcomes.
