Researchers have developed the Automated Two-Level Enrichment System (ATLES), a new device for the size-based classification of soil microorganisms. Published in 2026, the device provides a method for separating microbes without damaging delicate cell structures.
Why it matters
Traditional soil analysis often damages biological samples, hindering accurate study. This device offers a more efficient alternative for isolating specific microorganism populations for research.
The ATLES device uses a fluid pump and a self-cleaning membrane to isolate bacteria smaller than 2 micrometers from fungi larger than 3 micrometers. It achieves a 30% accuracy rate for size separation in tests.
The details
The device operates as a continuously self-cleaning sieve, utilizing a fluid pump to circulate liquid soil samples across a membrane. By constantly sweeping the liquid across the surface, the system prevents pore clogging, which maintains consistent flow and pressure. This mechanism separates cells based on physical dimensions without the mechanical force that typically damages biological integrity in conventional methods.

The Tech Race
This device advances the field of Nanotechnology and Precision Engineering by automating tedious biological classification tasks. It follows a path of replacing manual, destructive laboratory techniques with continuous, high-fidelity mechanical systems.
While currently in the research phase, this technology is designed to enable faster, more accurate analysis for soil scientists and environmental researchers. Future iterations aim to move the hardware from the laboratory to field-deployable settings.
The takeaway
The development of automated sorting systems signals a shift toward higher throughput and lower degradation in soil microbiome research. Researchers are now focused on scaling the device capacity and miniaturizing the system for use outside of controlled lab environments.
