FIGURE 4.2.14 Schematics of the colorimetric sensing of adenosine by aptamer-modified gold nanoparticles (AuNPs). 

A further example of optical sensing with water-soluble conjugated polymers was by Li et al, who reported a water-soluble polythiophene derivative that displays colorimetric and fluorescent responses to adenosine triphosphate...
