BIONEST | Advanced air eDNA sampler

trophy Awarded

BIONEST is an advanced air sampler designed for remote, long-term biomonitoring. It collects airborne eDNA while recording key contextual data to support accurate surveys. By enabling reliable, field-ready DNA capture, BIONEST addresses a significant gap in environmental science and offers a new approach to large-scale, sustainable biomonitoring.

Research and Opportunity

What is eDNA?

Environmental DNA (eDNA) is genetic material shed by organisms into their surroundings through skin cells, feathers, faeces, pollen and other biological fragments. Sampling eDNA from air, water or soil allows researchers to identify species present in an ecosystem, providing a non-invasive, highly sensitive method of biodiversity monitoring.

eDNA Process

Collect | Extract | Analyse | Report
The eDNA process begins in the field, where samples are collected, filtered, and preserved. These samples are then taken to the laboratory to extract, amplify, and sequence DNA. The resulting data is analysed and interpreted to identify species and ecological patterns. This information informs environmental decisions, supporting conservation, monitoring, and evidence-based action.

Why is edna important?

eDNA is important because it offers a non-invasive, highly sensitive way to understand what species are present in an environment. Traditional surveying can be time-consuming, expensive, and often misses rare or hard-to-find species. By analysing tiny traces of DNA in air, water or soil, eDNA can reveal hidden biodiversity, track threatened species, identify invasive organisms early, and support conservation decisions.

How can we push edna further?

While current eDNA methods have transformed biodiversity monitoring in water and soil, they still leave critical gaps in understanding terrestrial ecosystems. To push eDNA further, we need approaches that capture species signatures moving through the atmosphere. Airborne eDNA offers this opportunity. By sampling DNA suspended in air, researchers can detect flying insects, birds, mammals, plants, fungi and microbes without needing physical contact or visual sightings. This expands eDNA from point-based collection to continuous, landscape-scale monitoring, opening new possibilities for remote surveys, threatened species detection, and real-time ecosystem insights. Airborne eDNA is the next frontier—allowing biodiversity monitoring to become broader, non-invasive, and significantly more comprehensive than ever before.

So if you really want innovation, go air.

Problem areas

This diagram highlights vulnerable points across the eDNA workflow, from sample collection in the field, to laboratory processing, to data interpretation and ultimately environmental decision-making. At each stage, risks such as contamination, DNA degradation, logistical limitations, workflow inconsistencies, and misinterpretation of data can distort results. When these weaknesses compound, they can lead to inaccurate biodiversity information and poor environmental decisions. Strengthening reliability across the entire workflow is therefore critical to ensure that eDNA lives up to its potential as a trusted tool for ecological monitoring and conservation.

Issues within remote areas

Remote environments present significant challenges for eDNA biomonitoring. Field teams often work with limited access to electricity, clean water, refrigeration, specialised equipment, and reliable transport, making sample collection and preservation difficult. Long travel times increase the risk of DNA degradation, while dust, heat, humidity, and harsh weather heighten contamination and damage to equipment. Many remote regions also lack nearby laboratories, meaning samples must be transported over long distances before processing, which introduces additional risk and cost. These constraints can reduce data accuracy, limit survey frequency, and make long-term monitoring difficult. To support remote communities, ranger groups, and conservation efforts, eDNA tools must become more robust, field-ready, and less dependent on laboratory infrastructure.

When people go out to the field, they have really busy schedules…if you have a method that is too fiddly or involves specialised equipment that can break and stuff like that, people are not going to want to use it.

You might be in a very remote area and this is your chance to get there and that’s pretty much it.

Design development

Key considerations

Process

Design outcome

Water resistant

The angled vents and waterproofed internal components protect the sampler from rain while still allowing airflow for eDNA capture. By directing water away from the intake and shielding sensitive electronics, the design ensures continuous operation during wet weather. This weather resilience makes the device reliable in remote environments where sampling cannot stop due to changing conditions.

Taking current methods one step further

Unlike current airborne eDNA methods that focus solely on collecting particles, this sampler takes the next step by integrating contextual data sensors. By recording temperature, humidity, air flow, and other environmental conditions, the device links DNA detection to the real-world factors that influence how particles move and degrade. This added layer of data strengthens scientific interpretation, supports more accurate comparisons between sites, and helps researchers understand not just what species are present, but why and how they were detected.

Filter changes

The quick twist-and-pull mechanism allows the filter cartridge to be removed rapidly without tools, making sample collection efficient and reducing handling time in the field. This simplicity is valuable in remote environments where conditions may be hot, dusty, or unpredictable. By enabling fast cartridge changes, the design supports continuous sampling, minimises contamination risk, and makes the device accessible to non-specialist users such as rangers and community field teams.

Mounting

Using 1/4-20 screw compatibility allows the sampler to attach to existing tripod mounts, camera mounts, and field mounting systems already widely used by researchers and rangers. This removes the need for custom hardware and ensures quick, reliable setup in varied environments. By aligning with a universal standard, the device becomes more adaptable, easy to deploy, and compatible with equipment that field teams already own and understand.

Hanging

An adjustable flexible strap allows the sampler to be hung from trees, posts, or structures when mounting hardware isn’t available. This gives users more freedom to place the device in optimal sampling locations, even in uneven or vegetation-dense environments. The strap keeps the device secure, easy to access, and adaptable to diverse field conditions.
