Bailey Quinn Frank received the top prize at the 2026 Thermo Fisher Scientific Junior Innovators Challenge, announced on October 27. According to the official announcement by Society for Science, Bailey designed a low-cost environmental DNA sampler using a small fan and filter paper to collect airborne bacteria.

She was selected as the winner from a group of 30 finalists chosen from nearly 2,000 applicants across 47 states and five US territories.How Bailey developed an affordable air sampler Bailey’s project focused on environmental DNA, commonly known as eDNA, which allows researchers to study genetic material collected from the environment and identify organisms present in a particular location.

She explored whether an inexpensive device could capture airborne genetic material and support the detection of bacterial pathogens.According to her finalist profile published by Society for Science, Bailey built her sampler by attaching filter paper to small fans.

When switched on, the fans drew air through the device, allowing environmental material, including bacterial DNA, to collect on the paper. She collected two indoor air samples and one outdoor sample. After collecting the material, she purified DNA from the filter papers and transferred part of the collected sample to petri dishes to grow the bacteria.

She recorded the bacterial colonies after one week and attempted to identify them.Bailey also sent her best samples for 16S ribosomal RNA sequencing, a technique commonly used to help identify and classify bacteria. Her project examined whether the device could provide useful information about the microorganisms present in different environments.What her research revealed about indoor and outdoor air Bailey’s preliminary findings showed differences between the bacterial communities in indoor and outdoor air samples.

The indoor samples contained more bacterial genera associated with people, while the outdoor sample included bacteria associated with soil, water, air and plants. These findings helped demonstrate how an inexpensive sampler could collect material for further investigation of the microorganisms present in an environment.

The work also showed how students can apply scientific methods to questions involving public health and environmental monitoring.The device was designed around readily available materials rather than specialised, expensive equipment.

This approach is important because the cost of collecting and analysing environmental samples can be a barrier for communities and institutions with limited resources. However, the project represents an early investigation rather than a validated disease-monitoring system.

More testing would be needed to establish how reliably the sampler detects specific pathogens, how its performance compares with established equipment and whether it can support routine health surveillance.Why the device could matter for rural communities Bailey received the $25,000 Thermo Fisher Scientific ASCEND Award, the highest prize at the 2026 Thermo Fisher Scientific Junior Innovators Challenge.

The award recognised her environmental DNA project as well as her performance in the competition’s team challenges. The competition brought together 30 finalists selected from nearly 2,000 applicants representing 47 states and five territories.

The finalists collectively received more than $100,000 in awards, while each finalist’s school received a $1,000 grant to support science, technology, engineering and mathematics education.Alongside evaluating individual research projects, the competition tested participants’ critical thinking, creativity, communication and collaboration.

Challenges included designing sustainable cities, prioritising patients during a simulated outbreak, exploring the use of artificial intelligence to identify turtle species and building protective enclosures for diamondback terrapin eggs.

Other leading award recipients included Henry Grover and his twin brother Jack Grover, who investigated whether a water-absorbing gel could help prevent wildfires from reigniting. Myreen Ahsan used machine learning to identify molecules that could potentially target a protein associated with frontotemporal dementia, while Wileidy Enid Feliciano-Rivera developed biodegradable mulch from plantain peels.Bailey’s award highlights how an accessible scientific question can lead to a project combining practical engineering with environmental research.

Although her sampler requires further evaluation before it can be used for routine health surveillance, her work demonstrates the potential of young researchers to explore affordable approaches to real-world challenges.
