摘要:
The cluster size of colloidal particle arrays on pattern polyelectrolyte templates was controlled by adjusting the ratio of diameters of the colloids and patterned surface region. The method was based on the alternation of charged regions with neutral oligoethylene glycol regions which could act as resists to particle deposition. Results showed that the colloidal arrays remained stable even after extensive postprocessing and allowed one-to-one deposition of particles on specific confined regions.
