CdS quantum dots can be self-assembled on high surface area nanocrystalline TiO2 electrodes; spectroscopic and photoelectrochemical studies indicate that the size, and hence the absorption edge, of the CdS particles can be controlled; efficient photosensitization of the TiO2 electrode by the Q-particles has been achieved.
Site-selective assembly of 5 microm amine-functionalized glass spheres from aqueous suspensions onto gold surfaces patterned with carboxylic acid and methyl-terminated thiols has been achieved through the introduction of a variable tilt flow cell. In situ microscope imaging has been employed to study the four phases of assembly independently, and the(More)

Colloids Surf., A 2008, 327, 71) has demonstrated that, since convective forces have little influence over spheres in unstable sols, many conventional assembly techniques are ineffective for the organization of glassy spheres > or =5 microm in(More)
