A Sustainable, Wireless, Autonomous Nanocellulose-based Quantitative DoA Biosensing Platform
Background
Goal
Pilot lines & mass production
Pilot scale production of the biosensing platform
Printed electronics components
Sheet-to-sheet screen-printing is used for the fabrication of the NC-based functional components:
- Circuitry
- NFC Antenna
- Energy storage components
- Display
Biosensors
The innovative biosensors developed are able to detect five drugs of abuse in urine or saliva. For this, specific bio-inks are formulated and printed onto the nanocellulose substrate.
Silicon Microchip
It controls all printed electronic components, allowing:
- System monitoring
- Power management
- Control and reading of the electrochemical biosensor
- On-board data analysis
- Control of electrochemic display for data presentation
- Communication via NFC technology with external devices (e.g. smartphones)
Pilot scale production of the biosensing platform
Nanocellulose
Nanocellulose is a nano-sized material obtained through the mechanical or chemical delamination of wood and plant fibers. It is an emerging type of nature-derived and renewable nanomaterial that shows extraordinary mechanical and lightweight properties. Furthermore, nanocellulose has unique rheological properties, colloid stability, excellent film forming ability with very promising gas barrier properties. Consequently, nanocellulose is becoming one of the most promising sustainable building blocks for future advanced materials.
