A miniaturized, automated method for controlled printing of large arrays of nano- to femtoliter droplets by actively transporting mother droplets over hydrophilic-in-hydrophobic (“HIH”) micropatches. The technology uses single or double-plate devices where mother droplets can be actuated and HIH micropatches on one or both plates of the device where the droplets are printed. Due to the selective wettability of the hydrophilic micropatches in a hydrophobic matrix, large nano- to femtoliter droplet arrays are created when mother droplets are transported over the arrays. The parent droplets are moved by various droplet actuation principles. Also, a method using two plates placed one top another while being separated by a spacer. One plate is dedicated to confirming and guiding parent droplets by using hydrophilic patches in a hydrophobic matrix, while the other plate contains HIH arrays for printing of the droplets. When the parent droplet guidance plate is rotated over the plate dedicated to printing of nano- to femtoliter droplets, the droplets are dispensed inside the HIH array utilizing their selective wettability. The methods allow the parent droplets to move over the HIH arrays many times, providing advantages for performing bio-assays or miniaturized materials synthesis in nano- to femtoliter sized droplets. With controlled evaporation of the dispensed droplets of solution, large arrays of printed material can be generated in seconds. The methods provide a nano- to femtoliter droplet printing technique for a wide variety of applications, e.g., protein- or cell-based bio-assays or printing of crystalline structures, suspensions of nanoparticles or microelectronic components.
