Smart and remote sensing technologies offer significant advantages across various applications. This study introduces an innovative approach integrating printed electrochemical nanosensors with a remotely controllable underwater robot, creating "Robo-sensor" for surface water sensing. Unlike conventional sensors, the Robo-sensor operates in three dimensions, both on underwater, targeting specific locations such as coastal areas deep-sea environments while transmitting data to external analytical unit. To achieve this, we developed conductive nanoink by combining graphite, silver nanorods (AgNRs; diameter: 30 ± 20 nm, length: 2 0.2 μm), nail polish cohesive agent, organic solvent. ink was used fabricate electroanalytical system mini-robot's body. The Robo-sensor, connected portable potentiostat, demonstrated linear responses hydroquinone (HQ) nitrite ions, detection ranges of 5.0–1356.0 3.0–1200.0 μM, respectively, under artificial seawater conditions (High salinity). Its repeatability (RSD <6%), stability (up 40 continuous applications error < 10%), sensitivity were thoroughly evaluated. Robo-sensor's practical included detecting chemical leaks pipelines containing HQ, hazardous relevant industries petrochemicals. Additionally, it analyzed contaminated NO2– near far from wastewater discharge pipeline, providing valuable insights environmental ecosystem investigations. In conclusion, enables on-site analysis reducing time, costs, risks high-hazard like deep waters. With further modifications, this strategy could be adapted diverse applications, including offshore oil petrochemical operations, corrosion studies, monitoring, thus expanding real-world impact science.
