Devices and associated methods are provided herein for creating arrays of thin films on a substrate utilizing a capillary force layer-by-layer assembly. Such devices and methods can be configured for forming one or more channels when the device is in operable contact with the substrate, each channel having an inlet reservoir at one end by which the coating material is introduced into the channel, wherein each channel is a lengthwise enclosure defined by a surface of the substrate on one side and one or more adjacent structures of the assembly surrounding the channel along its length. Provided devices and methods facilitate automated, precise manufacture of arrays of customized thin films for lab-on-a-chip biological and/or chemical assay products, for example. Additionally, provided devices and methods significantly reduce material waste, improves quality control, and expands the potential applications of LBL into new research space. |
