Abstract Scope |
Real-time detection of heavy metal traces from industrial waste is key to control any potential pollution by early intervention. Despite the promising performance of novel technologies, the chances to transfer the lab-scale platforms to successful commercialization stages are dramatically low. We propose for the first time the use of ink-jet printed gold electrodes as a reliable, stable and fully-scalable approach for aptamer-based detection of mercury (Hg2+) traces in water and organic solvents. The controlled fabrication process was demonstrated with an RCT variation within +/- 1 SD (RSD= 2.92%). The LOD reported is 0.01 ppm in water and enhanced sensitivity of 2-fold in organic solvents (LOD = 0.005 ppm), both in compliance with EPA regulation. To the best of our knowledge, this work reports for the first time a gold inkjet-printed impedimetric platform for aptamer-based detection of Hg2+ in organic solvents, showing promising viability for future prototyping and scaling-up. |
