Abstract / Description of output

In recent years, chemical sensors have shown the potential to provide rapid, accurate, and on-site quantitative detection of analytes, but current methods often require specialised equipment. In this study, a novel dye-sensitised solar cell (DSSC) based sensor is reported for convenient detection of tert-butylhydroquinone (TBHQ) in drinking water. The sensor consists of a gold nanoparticle (AuNP) solution based unit that responds to the concentration of TBHQ and produces an electrical signal change via an integrated DSSC based transducer component. Through analysing the current signal generated by the DSSC sensor, the quantity of TBHQ in an unknown sample can be achieved. Finite difference time domain (FDTD) simulation has been used to explain the relationship between the particle morphologies and optical properties of AuNPs. This work offers a novel strategy of developing portable sensors without needing any scientific instrument.
