“…In the transfer process, HDT molecules that exist between the wells are also printed to the contacting regions of the glass surface. According to the computer simulation by Bucknall and co-workers, [16] it is supposed that the guided dewetting can confine the DA-PEG fluids in the regions absent of HDT. Owing to this feature, wettability controlled self-assembly has been chosen to fill the microwells and to control the ring topology, although other methods such as spin coating and withdrawing the stamp vertically from a solution have also been used before.…”

Microgel rings have been fabricated on a glass surface by a micro‐transfer technique. The polymer melt is transferred to the substrate surface in a confined space with a picoliter volume along the boundary of the polymeric stamp. The surface of the polymer features is smoothened by surface tension in an annealing cycle, which results in isotropic rings. After cross‐linking, the microgels respond swiftly when immersed in water. Asymmetric rings are also obtained by tilting the substrate. The microgels can detach from the substrate to form a suspension of the rings. Conjugated rings have also been fabricated by supplementing functional molecules into the poly(ethylene glycol) network.magnified image

“…In the latter case, a meniscus is observed at the protruding end of the polymer as shown in Fig. 1b; if combined with a "moulded dewetting" process, 19 further annealing could allow the meniscus film to fully dewet from the centre of the meniscus which forms the thinnest part of the film (Fig. 2).…”

Since its inception as a simple, low cost alternative to more complicated lithographic techniques such as electron-beam and dip-pen lithography, capillary force lithography (CFL) has developed into a versatile tool to form sub-100 nm patterns. Utilizing the concept of a polymer melt, structures and devices generated by the technique have been used in applications varying from surfaces regulating cell growth to gas sensing. In this review, we discuss various CFL methodologies which have evolved, their application in both biological and non-biological research, and finally a brief outlook in areas of research where CFL is destined to make an enormous impact in the near future.

“…However, by combining with other techniques, much higher resolution could be obtained. 9 In this work, a method combining µCP with self-assembly of nanoparticles at liquid/liquid interface is applied to produce highly ordered array patterns with feature size smaller than that on the stamps. In this method, µCP is used to create chemical patterns on substrates, which induce selective condensation of water droplets.…”

Highly ordered arrays consisting uniform fluorescent cadmium selenide (CdSe) quantum dots (QDs) ring or dot structures were obtained by self-assembly of QDs on chemically patterned substrates. In this method, Au substrates with alternating hydrophobic and hydrophilic square patterns are firstly fabricated by microcontact printing, which allows water droplets to condense on the hydrophilic regions to provide two-dimensional template arrays. The CdSe QDs are then assembled at the liquid/liquid interfaces to give uniform micro or nanostructures. The shape and size of the rings and dots can be tailored by controlling the relative evaporation speed of the water and the organic solvents. The obtained nanostructures have ideal topography to avoid substrate-induced fluorescence quenching.
