Special Issue Information

Dear Colleagues,

The application of nanotechnologies for nano-sized biosensing devices provides innovative tools able to foster analytical devices in the sectors of health, medicine, food, environment, and agriculture. These results lead to equipment that is less invasive and with improved features in terms of sensitivity, selectivity and stability over time. In particular, nanomaterials have proved to be extremely useful concerning their capability to enhance the performance of sensing means, as well as representing innovative and competitive biosynthetic recognition elements for specific analytical targets.

In the last few decades, some concerns have arisen about nanomaterials, especially regarding issues related to human health and environmental protection. For these reasons, the urgency to develop a more sustainable line of research has been strong.

Currently, green nanotechnology works on two fronts: the synthesis of nanomaterials from biological routes, as well as the improvement of traditional production protocols to provide new possibilities with minimal requirement of hazardous substances and strongly reduced energy needs.

Furthermore, the growing interest in circular economy procedures has resulted in emerging scientific interest regarding the recovery of waste materials and its transformation into valuable resources and final products. This new point of view supported the development of intriguing new protocols to produce both traditional and innovative nanomaterials, starting from other syntheses and/or industrial processes using residual materials.

The aim of this Special Issue of Nanomaterials is to provide a platform of manuscripts comprising original research results, reviews, and short communications in the field of innovative green nanomaterials, their use in sensor and biosensor development and application to real-life systems.

In this study, we report a novel way to produce carbon-based conductive inks for electronic and sensor technology applications. Carbonized lignin, obtained from the waste products of the Eucalyptus globulus tree paper industry, was used to produce a stable conductive ink. To this end, liquid-phase compositions were tested with different amounts of carbonized lignin powder to obtain an ink with optimal conductivity and rheological properties for different possible uses. The combination that showed the best properties, both regarding electrochemical properties and green compatibility of the materials employed, was cyclohexanone/cellulose acetate/carbonized lignin 5% (w/w), which was used to produce screen-printed electrodes. The electrodes were characterized from a structural and electrochemical point of view, resulting in an electrochemically active area of 0.1813 cm2, compared to the electrochemically active area of 0.1420 cm2 obtained by employing geometrically similar petroleum-based screen-printed electrodes and, finally, their performance was demonstrated for the quantification of uric acid, with a limit of detection of 0.3 μM, and their biocompatibility was assessed by testing it with the laccase enzyme and achieving a limit of detection of 2.01 μM for catechol as the substrate. The results suggest that the developed ink could be of great use in both sensor and electronic industries, reducing the overall ecological impact of traditionally used petroleum-based inks.
