ELECTROCHEMICAL PAPER-BASED ELECTROCHEMICAL (BIO)SENSORS FOR THE NEXT GENERATION OF ANALYTICAL TOOLS

The Eleventh International Workshop on Biosensors, organized by Professor Aziz AMINE, Hassan II University of Casablanca, are held in Marrakech (Morocco), from3rd to 5th October, 2024. This workshop bring together experts and those who are interested in the themes of the workshop. It include plenary lectures, Keynote lectures, oral and poster presentations. Participating in this conference is always a pleasure because it takes place in a convivial atmosphere with the presence of about 90 people that allows to exchange ideas and intentions. The topics are: · Electrochemical biosensors · Optical biosensors · Nanobiosensors & nanomaterials · Label-free biosensors · Nucleic acid sensors and aptasensors · Enzyme-based biosensors · Nanozyme-based biosensors · Immunosensors · Wearable biosensors · Molecularly imprinted Polymers based biosensors · Whole cell-based biosensors · Natural & synthetic receptors · Printed biosensors and microfabrication · Microfluidics · Commercial biosensors I participated as an invited speaker with the keynote lecture “ELECTROCHEMICAL PAPER-BASED ELECTROCHEMICAL (BIO)SENSORS FOR THE NEXT GENERATION OF ANALYTICAL TOOLS”. I presented the Phoenix-OoC mission as a point of arrival by way of showing my different maximum influential works that allowed me to get to this undertaking. I highlighted the distinct benefits of the use of paper in biosensor improvement, as mentioned in my review, "Electrochemical paper-based devices: When the simple replacement of the support to print ecodesigned electrodes radically improves the features of the electrochemical devices" published in Current Opinion in Electrochemistry SI: Emerging Opinions (2022) [F. Arduini. Curr. Opin. Electrochem. 2022, 101090]: “Paper-based electrochemical (bio)sensors have emerged as highly attractive analytical devices for their superior sustainable features, such as avoiding the use of polyester as support and the reduction of waste, being incinerated after use. However, paper-based electrochemical (bio)sensors have recently demonstrated further advantages, including the simple combination with vertical microfluidics and their use as a reservoir to deliver smart electrochemical (bio)sensors able to i) contain the reagents, ii) preconcentrate the target analyte, and iii) synthesize the nanomaterials inside the paper network. Furthermore, these devices have demonstrated their ability to overcome the limitations of the other printed electrochemical sensors in the measurement of entirely liquid samples by detecting the target analyte in the aerosol phase or solid sample, without the additional sampling system. These achievements highlight their valuable and varied advantages in the sensing sector”.
