Lighting the Way: How Bioluminescent Sea Dye Markers Save Lives


It started with a simple question: What if we could light up the ocean—instantly, safely, and without chemicals?


Nearly two years later, with the support of the Canadian Coast Guard and the Vancouver Island Arrowsmith Search and Rescue team, we activated the world’s first bioluminescent sea dye marker.


The Problem We’re Solving

Minutes matter when someone goes missing at sea. Search and rescue teams rely on two types of signals we are focused on improving: chemical light sticks and fluorescent sea dye markers. But both come with real costs:


Chem lights:

  • Toxic residue contaminates marine environments

  • Limited lifespan and unpredictable performance

  • Weight and volume constraints for rescue teams

  • Single-use plastic adds to ocean pollution

Fluorescent sea dye markers:

  • Not visible at night!


Our Solution: Biology Instead of Chemistry

Our bioluminescent marker uses the same natural process that makes fireflies glow:

  • Water-activated

  • No batteries

  • No chemicals

  • No plastic waste

  • Emits its own light


Performance Highlights

1 gram of enzyme produces up to 1 litre of light
1 litre of water, 1 gram of enzyme — Lux Bio's bioluminescent sea dye marker.
1 litre of water, 1 gram of enzyme — Lux Bio's bioluminescent sea dye marker.
  • Instant activation

  • Bright, visible light detectable by search teams and aircraft

  • Biodegradable — breaks down naturally

  • Effective in day and night conditions


Field Testing in Real Conditions

Across 2025, we’ve been piloting prototypes across diverse environments:

  • Multiple weather conditions

  • Day and night testing

  • Night-vision compatible

  • Real-world deployment with rescue teams


Upcoming pilots: Partners include Canadian Coast Guard, US Navy, and more coming soon!


Why This Matters Beyond Search & Rescue

This technology is the foundation for a larger shift:

  • Safer maritime operations

  • Reduced reliance on toxic chemicals

  • Cleaner oceans

  • Lighter, more reliable defence solutions


This is dual-use technology — innovation that serves defence needs while protecting the planet.


What’s Next

We’ll share field-testing results and expand partnerships with additional agencies.
