Low-Cost Living Biosensors That Detect Chemicals, Light, and Touch Using Slime Mould

environmentPilotedTRL 6

Imagine a tiny organism — a slime mould — that reacts to chemicals, light, and touch by changing its electrical signals, almost like a living smoke detector. Researchers figured out how to read those signals and turn them into useful measurements. They built a cheap, portable sensor around this living creature so anyone — not just lab scientists — can measure air quality or detect substances. The goal was to make these biosensors affordable enough to sell to schools, universities, and curious citizens.

The business problem

What needed solving

Traditional chemical and environmental sensors are expensive, complex, and require trained operators — putting them out of reach for small labs, schools, and community monitoring programs. There is a gap in the market for ultra-low-cost, easy-to-use sensing devices that can screen for volatile chemicals and environmental stimuli without specialized equipment.

The solution

What was built

The project manufactured a first batch of Physarum-based biosensors ready for sales, built on low-cost electronics and bespoke software. The sensor uses living slime mould as a transducer that converts chemical, optical, and tactile stimuli into readable electrical signals.

Business applications

Who can put this to work

Environmental Monitoring Equipment

SME

Target: Companies manufacturing portable air quality sensors or pollution monitoring devices

If you are an environmental sensor company dealing with the high cost and complexity of chemical detection arrays — this project developed a living biosensor using slime mould that maps volatile chemicals into unique electrical signal patterns. The sensor is built on low-cost electronics and was declared ready for sales as a manufactured product. It could complement or replace expensive chemical sensor arrays for screening applications.

Food Safety Testing

SME

Target: Food testing laboratories and quality assurance equipment suppliers

If you are a food safety testing company dealing with the need for rapid, affordable screening of chemical contaminants — this project developed a biosensor that responds to a wide range of volatile chemicals with distinct frequency and amplitude signatures. The slime mould transducer can infer the nature of an unknown stimulus from its electrical response. This could serve as a low-cost first-pass screening tool before expensive lab analysis.

Education Technology

SME

Target: Science education kit suppliers and STEM learning platform providers

If you are an education technology company looking for engaging hands-on science products — this project created a user-friendly biosensor kit specifically designed for schools, universities, and citizen scientists. The product combines a living organism with low-cost electronics and bespoke software, making it a compelling teaching tool for biology, electronics, and data science. The first batch of sensors was manufactured and declared ready for sales.

Frequently asked

Quick answers

What would a Physarum biosensor cost compared to traditional chemical sensors?

The project explicitly designed for cost-effectiveness, using low-cost electronics as the hardware base. Based on available project data, exact pricing is not disclosed, but the target market includes schools and citizen scientists, suggesting a consumer-accessible price point rather than industrial-grade pricing.

Can this technology scale to industrial volumes?

The project delivered a first batch of manufactured Physarum-based sensors declared ready for sales. However, the consortium is a single university with no industrial manufacturing partners. Scaling production would likely require partnerships with electronics manufacturers or biosensor companies.

What is the intellectual property situation — can we license this?

The technology was developed at the University of the West of England, Bristol. Based on available project data, IP ownership rests with the university. Any licensing or commercialization would need to be negotiated directly with UWE Bristol's technology transfer office.

What exactly can the sensor detect?

The slime mould maps a wide range of volatile chemicals, tactile stimuli, and light of various wavelengths into unique combinations of frequency and amplitude of electrical potential oscillations. Given an unknown stimulus, the nature of the stimulus can be inferred from the signal pattern. Specific chemical lists are not detailed in the available project data.

Is there regulatory approval for using a living organism as a sensor?

Based on available project data, no regulatory approvals are mentioned. The sensor uses Physarum polycephalum, a common non-pathogenic organism. Any deployment in regulated industries like food safety would require appropriate certifications, which this project did not address.

How long does the living sensor last before needing replacement?

Based on available project data, the operational lifespan of the slime mould transducer is not specified. Physarum polycephalum can be maintained and regrown relatively easily, but practical shelf-life and replacement cycles would need to be confirmed with the research team.

Consortium

Who built it

This is a single-partner project run entirely by the University of the West of England, Bristol — no industrial partners, no SMEs, and no cross-border collaboration. For a business buyer, this means the technology is firmly academic in origin. There is deep research expertise but no built-in manufacturing, distribution, or commercialization capability. Any company interested in this technology would need to bring its own production and go-to-market infrastructure, and negotiate directly with UWE Bristol for access.
