The PLA/Au NPs/indium tin oxide (ITO) electrode was used as an electrochemical biosensor for the selective identification of leukemia cancer cells . Silver nanowires improved the conductivity of PLA . PLA/Ag NPs were reported as electrodes for the organic lightemitting diodes (OLEDs) . It offered high transparency with good electrical conductivity, even after 10 000 cycles . AgNPs-Ni2O3 improved the electrical conductivity of cellulose nanowhiskers/polypyrrole . Ag NPs can be also used to improve the electrical conductivity for chitosan . The perfect interconnection between polymers and conductive nanofillers is critical for constructing a conductive nanocomposite. The homogenous distribution of nanofiller in the polymer nanocomposite improved the electrical conductivity of the composite. Naturally, the nanofillers tend to distribute randomly in the polymer matrix. It was reported that some fillers tend to spread to the polymer's surface at higher concentrations.
