Dual-Use Biodefense Applications

Biological Readiness, Engineered.

CLOAK engineers the skin's native microbiome into a long-duration barrier against disease-vector insects, built to satisfy civilian regulatory standards and defense-grade reliability requirements alike.

Threat Landscape

Vector-borne disease remains a persistent, escalating burden on global public health and operational readiness.

700M
Annual reported cases, mosquito-borne disease
1M
Annual deaths, across 85 countries
1–4 WKS
Operational non-availability per incident

Expanding vector habitat range, driven by climate shift, continues to increase exposure risk across both civilian and operational populations.

Global Health

CLOAK is engineered as a candidate addition to the global malaria-eradication toolkit, operating alongside case management, vector control strategies, and vaccines.

Defense

Engineered for continuous operational environments and designed to meet U.S. Department of War and NATO mission-readiness standards, without dependence on manual reapplication cycles.

System Architecture

Engineered Defense, Not Chemical Suppression.

CLOAK engineers naturally occurring, non-pathogenic skin bacteria to modify the chemical signals mosquitoes use for host detection. Protection is engineered at the source of attraction, not by masking with topical chemical agents.

Extended Operational Uptime

A single application maintains verified efficacy for eleven or more days in in vivo animal studies.

Zero Chemical Signature

No active chemical agents, no residue, no detectable scent profile.

Broad-Spectrum Repellency

Verified efficacy across the Aedes, Anopheles, and Culex genera, plus sandflies.

Leadership
