Накратко на български

Биопластмасите се изследват за създаване на биоразградими сензори за пот чрез лазерно генериране на графен. Това помага за намаляване на пластмасовите и електронните отпадъци от еднократните медицински лепенки.

Functional Laser Induced Graphene from natural bio-plastics (bio-LIG), sustainable composites for non-invasive wearable sweat sensor platforms

What is the problem/issue being addressed? SusBioLIG addresses the increasing demand by the United Nations World Commission on Environment and Development towards minimization of the massive amount of plastic and electrical waste associated to the colossal increase in demand for disposable wearable sensors and patches1. In parallel the project seeks to address crucial knowledge gaps in the emerging field of green sensing by investigation of a novel environmentally friendly method for the fabrication of biodegradable wearable sensors. The actual knowledge gaps are based on the challenging requirements for the ambitious achievement of “green” sensing, necessitating the combined and concomitant availability of i) highly abundant and low cost precursors with ii) high throughput green synthetic routes compatible with iii) low cost processing routes and leading to iv) biodegradable (compostable) and/or recyclable devices. Why is it important for society? As it stands the proposed bio-LIG method constitutes the first example of sensing platforms made entirely from sustainable bioplastic materials and fabricated by means of green technologies. The greatest innovation of the project relies on the merging of LIG & bio-plastics technologies that, when successful, will realise the potential of a fully biodegradable functional bio-plastic material for point-of-care (POC) sensing, replacing single-use plastics derived from fossil fuels. Therefore, from a technological & scientific perspective, this can open up a host of new possibilities in material science not previously envisioned, whereby tailorable biopolymers can be situationally and environmentally re-purposed and re-used to match the needs of the user. Further novelty arises from addressing the EU and global increasing concern associated to the environmental impact of plastic waste. In this respect, the proposed technology and materials meet all requirements stated by the Circular Economy Action Plan, one of the main blocks of the European Green Deal, and part of Europe's transition towards a circular economy, and will also contribute to reaching the Sustainable Development Goals, the global climate commitments and the EU's industrial policy objectives. What are the overall objectives? The overall aim of SusBioLIG is to use of biopolymer composites for the fabrication of next generation all natural and biodegradable wearable sensing platforms based on the synthesis of high quality graphene-like structures by direct laser writing (laser induced graphene, LIG).

Цел на проекта

Wearable sensors have the potential to revolutionise traditional health and wellbeing diagnostics by enabling personal healthcare monitoring everywhere and anytime. However, the increased demand, ubiquity and the inherent disposable nature of wearable sensors poses serious environmental concerns both in terms of high energy production requirements and end-of-life disposal. These concerns mandate urgent development of “green” materials and processes to ensure future sustainability of the wearable sensor sector. The project proposes a simple one-step, scalable approach for producing and patterning porous graphene films with three-dimensional networks from chitosan using laser writing technique (bio-LIG). SusBioLIG will start with investigation of the bio-LIG process to find the chemico-physical mechanism enabling LIG formation on chitosan. The effect of laser irradiation parameters, the percentages of individual components will be investigate in order to optimize standard formulation morphology and electrical conductivity. Obtained composites will be assessed by electrical characterisation and spectroscopic techniques. Finally, Bio-LIG electrode arrays will be designed and fabricated will be characterized by scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy. Label free electrode and functionalized electrodes by GOx and LOx will be used as sensing platforms for uric acid, glucose and lactate respectively. Direct electron transfer and or Prussian blue mediated electron transfer studies will be carried out for glucose and lactate. After electrochemical (e.g. cyclic voltammetry, differential pulse voltammetry and chronoamperometry) behavior studies of targeted biomarkers at electrode array platforms, affecting parameters will be optimized. Then, simultaneous detection of targeted biomarkers in an artificial sweat sample will be performed and figures of merit for each biomarkers will be obtained and compared.
