InP and InAs quantum rods were synthesized via the reactions of monodispersed indium droplets with phosphide or arsenide ions, respectively. In these reactions indium droplets, which do not act as a catalyst but rather as a reactant, are completely consumed. For the synthesis of InP and InAs quantum rods with a narrow size distribution, a narrow size distribution of indium particles is required because each indium droplet serves as a template to strictly limit the lateral growth of individual InP or InAs nanocrystals. Free-standing InP (130 Å diameter and 870 Å length) and InAs (180 Å diameter and 745 Å length) quantum rods without residual metallic catalyst at the rod tip were synthesized from the diluted transparent solutions of metallic indium. Both kinds of synthesized nanorods are in the strong confinement regime since the Bohr diameters of InP and InAs are 200 and 700 Å, respectively.

The membrane emulsification-suspension polymerization (MESP) method was used to synthesize hypercrosslinked microspheres with a narrow size distribution. The resulting polymers possessed large specific surface area (over 1300 m2/g) and their particle size was controllable. The particles were more hydrophilic when using nitrobenzene as solvent instead of 1, 2-dichloroethane in the postcrosslinking process.
