Thus, rod-like nanoparticles are preferred in many applications. However, their synthesis is more complicated than the synthesis of nanospheres since the

Self-assembled monolayers (SAMs) prepared from dilute solutions of multidentate

Next, a 0.01 mM solution of multidentate thiol was injected into the liquid cell. As time progressed, molecular-level details of the surface

The multidentate molecules have a more complex assembly pathway than monothiol counterparts, mediated by sequential steps of forming S

• synthesis. This being the case, THMA is also likely to bind strongly to ZnO nanowire surfaces. The presence of the three hydroxyl groups in THMA ensures multidentate binding to the ZnO surface and is likely to facilitate hydrogen-bonding type interactions with surface-adsorbed hydroxyls under our surface
