Paper-based electrochemical (bio)sensors

The use of paper has opened to a new development towards the design of brand-new portable analytical devices. In particular, it has allowed to overcome some limitations  of previous systems: the porosity of paper allows to actively operate within the analytical procedure by pre-treating the sample, loading reagents, making reactions happen and printing electrodes. The creation of all-in-one and sustainable devices acquires a stronger value being tools for society.

Nanoparticles and nanocomposites

The use of nanomaterials has highlighted obvious enhancement in the field of analytical science. Respect to their bulk counterparts, nanoparticles and nano composites have been showing great performances. Novel synthetic strategies, e.g. paper-based synthesis, and improved combinations between different sources of nanosized matters are capable to enhance sensitivity and reliability of detection architectures.

Liquid biopsy and healthcare

The detection of circulating cancer biomarkers, e.g ctDNA, miRNA, tumor cells, exosomes, also known as liquid biopsy, opens up a revolutionary opportunity in cancer detection and therapy monitoring and has been listed within the top 10 of global emerging technologies. The development of point of care devices for cancer research is gaining a lot of attention within the sensor community. The possibility to get rapid information in tiny amount of bodily fluids is the challenge.

Re-inventing analysis

The search of novel materials/scaffolds to be integrated in smart architectures for sensing devices represents a hot topic in analytical chemistry. To date, both optical and electrochemical methods have been combined with the most diverse (and un-common) materials: pins, origami, removable tattoos, film for packaging, office paper. All these examples highlight the suitability of certain materials, generally employed in different context, to be used for reaching “different” analytical answers.

Sometimes, the routes to produce the optimal device might be time-consuming and costly. The role of chemometric-based tools is strategic in the conceptualization, production, and data analysis in developing reliable portable devices and also decrease the amount of experiments (thus, costs) at the same time.
