Plastics: friend or foe? Polymers for monitoring of environmental contaminants

About this event

Molecularly Imprinted Polymers (MIPs) are porous materials that enable specific binding of their respective target molecules; while they mimic the affinity of natural recognition elements, they are low-cost, robust (can withstand extremes of pH and T), and can be used for templates as small as ions to large macromolecules. Furthermore, MIPs are produced using animal-free technology, an important aspect considering still 1 million animals are used in the EU per year and there is a current ban on use of animal-derived antibodies.

In this talk, I will show how we can integrate MIPs into modified screen-printed electrodes (MIP-modified SPEs) and use them for sensing of environmental contaminants [1]. Specifically, I will talk about aspects of reusability and use of paper as substrate material to promote sustainability. The sensors are used to measure caffeine, an anthropogenic marker of water contamination, a range of antibiotics [2], and microorganisms to provide information about water quality. I will demonstrate both our standalone thermal sensor platform that is used for rapid screening of samples [3] to more common techniques involving electrochemical detection. Our sensors can be used for fast and low-cost detection performed on-site considering the enhanced stability of the MIPs, which holds great potential for the determination of contaminants in environmental samples. Moreover, this is a platform technology and can be adapted to an array format containing a range of markers.
