We have demonstrated that gold nanoparticles (AuNPs) can effectively associate with enzyme through spontaneous adsorption to afford supramolecular complexes, resulting in a significant increase of its enzymatic activity. In this work, we embarked on a study of the interactions between the different-sized AuNPs and the substrate through quantifying the kinetic parameters (K(cat) and K(m)). The diversity of size allows us to probe the role of catalytic behaviors in modulating enzymatic activity.

Poly(3-hexylthiophene) (P3HT) field-effect transistors (FETs) are fabricated on glass substrates with SiO2 as a gate dielectric over the gate. Indium tin oxide (ITO), Al, and Cr are employed as gate metals. For spin-coated FET, the mobility increases from 10(-4)-10(-5) cm(2)/V s for ITO and Al gates to 10(-2) cm(2)/V s for Cr gate. After O-2 plasma treatment, the SiO2 roughness can be made as low as 0.7 nm. The mobility is further improved up to 0.3 cm(2)/V s by dip-coating P3HT. "Crossed rods" such as morphology can be observed in dip-coated FET with high mobility, indicating high degree of self-assembly facilitated by the flat SiO2 surface over Cr gate.
