FAQ

Common questions about microplastic detection, 5mm services, and our site sections.

What is DECOMPOSITION?

We develop enzyme-based fluorescent biosensors for micro- and nanoplastic detection and operate 5mmTEST (testing), 5mmLAB (kits), and 5mmSHOP (consumer care products).

How does microplastic detection work?

Patented plastic-degrading enzymes react with microplastics in the sample; fluorescence from the reaction is measured to estimate concentration. Analysis uses a microplate reader instead of costly FT-IR+μ systems. See the Technology page for details.

What is the difference between 5mmTEST and the 5mmLAB kit?

5mmTEST is a testing service—you send samples for standardized analysis. The 5mmLAB kit is for in-house lab use with a microplate reader. Visit 5mmtest.com for testing; see Products for the kit page.

How long until results?

With the 5mmLAB kit, roughly within 5 hours from prep to result per run (varies by batch). 5mmTEST turnaround depends on intake and lab schedule.

What samples can be analyzed?

Water (drinking, tap, filters), marine/environmental, and research samples. 5mmTEST focuses on household and institutional water; kits support in-house lab workflows. See Technology for applications.

Where can I buy 5mmSHOP products?

At 5mm.shop and Naver Smart Store. Links are on the Products page.

Technology vs. Research pages?

Technology explains how our detection stack works (workflow, specs, cleaning, microbes). Research covers R&D themes, collaborators, validation, and the microplastic map.
