The air−water droplet interface guides the assembly and determines the shape of the resulting micropatches. We report the results of a systematic study of the mechanism of interface-templated assembly on substrates of controlled contact angle. The kinetics of drying were examined by measurements of droplet profiles, and it was found that the rate matched diffusion-limited evaporation well. The shape of the droplets and of the resulting assemblies was correlated to the dynamics of the receding contact line. The effects of major parameters controlling the process, including contact angle, particle concentration, and electrolyte, were investigated in detail. A variety of micropatch shapes were observed and categorized within the parameter space. The in-depth characterization of the process allowed the optimization of the assembly and the formulation of protocols for the deposition of nanostructured patches of different diameter, thickness, and shape.}, number={4}, journal={LANGMUIR}, author={Kuncicky, Daniel M. and Velev, Orlin D.}, year={2008}, month={Feb}, pages={1371–1380} }

The advantages afforded by this method are improved process efficiency and reduced material consumption relative to standard dipcoating techniques. Structured coatings larger than a few square centimeters are deposited in minutes from aqueous suspension volumes of approximately 10–20 μl. The governing mechanism of particle deposition is convective assembly at high volume fractions. Our research with monodisperse polystyrene latex showed that a volumetric flux balance incorporating the evaporating solvent and assembling particle fluxes can accurately relate the deposition process parameters to the coating structure and properties. Operational ’phase’ diagrams were constructed that demonstrate good correspondence between coating thickness and structure to the operational parameters of the coatings process predicted on the basis of the material balance model. These ’phase’ diagrams may be instrumental in turning the colloidal deposition into a usable and scaleable technology. This deposition technique can be applied to a variety of colloidal systems, including the fabrication of conductive and antireflective coatings, surface-enhancing Raman scattering (SERS) substrates, and lithographic masks.}, number={1-3}, journal={COLLOIDS AND SURFACES A-PHYSICOCHEMICAL AND ENGINEERING ASPECTS}, author={Prevo, Brian G. and Kuncicky, Daniel M. and Velev, Orlin D.}, year={2007}, month={Dec}, pages={2–10} }

The structure-dependent performance of these SERS substrates was systematically characterized with cyanide in continuous flow microfluidic chambers. A matrix of experiments was designed to isolate the SERS contributions arising from nano- and microscale porosity, long-range ordering of the micropores, and the thickness of the nanoparticle layer. The SERS results were compared to the substrate structure observed by scanning electron microscopy (SEM) and optical microscopy to correlate substrate structure to SERS performance. The Raman peak intensity was consistently highest for nanoporous substrates with three-dimensionally ordered micropores, and decreases if the micropores are not ordered or not templated. Removing the nanoscale porosity by fusion of the nanoparticles (without removing the large micropores) leads to a drastic plunge in substrate performance. The peak intensity does not strongly correlate to the thickness of the nanoparticle films. The results make possible the efficient controlled fabrication of stable, reproducible, and highly active substrates for SERS based chemical sensors with continuous sampling.}, number={4}, journal={APPLIED SPECTROSCOPY}, author={Kuncicky, DM and Christesen, SD and Velev, OD}, year={2005}, month={Apr}, pages={401–409} }
