Ong and coworkers [110] introduced a nanoparticle approach to coat a polymeric semiconductor. The authors dispersed PQT in dichlorobenzene by sonicating a hot solution and subsequently cooling it to room temperature. The idea was to predetermine the polymer ordering before coating it onto the substrate. Increased mobility was reported compared to hot solution coating. 

Small silver nanoparticles are stabilized by ionic species that adsorb to their surface, much like the citrate ions prevent rapid agglomeration of gold nanoparticles. The ionic repnlsion experienced by the silver particles are likely due to carboxylic acids that form after the oxidation of aldehydes. Upon the addition of o er ionic species, the silver nanoparticles approach each other more easily and grow in size. Stndents observe a change in color from yellow to green as the plasmon resonance band shifts to longer wavelengths.
