The tool made use of for stretching the sample. Figure 1. The tool employed for stretching the sample.The assembly was sprayed with SU-8 developer (Microchem Newton, MA, USA), which resulted in dissolution from the unexposed photoresist film that lay between the Polmacoxib Autophagy crossClamping Stretching Gluing Releasing linked PDMS film and also the BOPET film, and therefore removal of the BOPET film. The surface of the PDMS film was rinsed successively with fresh developer and deionized water ahead of drying. Ultimately, the displacements applied towards the PDMS sheet had been released in each planar directions simultaneously, which produced an array of curved film microstructures. The forming approach of film microstructures corresponding towards the fabrication methods is shown in Figure 2b. The MRTX-1719 Epigenetic Reader Domain two-dimensional (2D) morphology of the curved film microstructures was assessed by using an optical microscope (Olympus STM6-F10-3, Olympus Co., Tokyo, Ja(b) pan), while the 3D morphology of the curved film microstructures was assessed by utilizing a laser scanning confocal microscope (Nikon A1, gold-coated, Nikon, Tokyo, Japan). The 2D cross-sectional view in the curved film microstructures was examined by optical microscope (Nikon SMZ1270, colored film microstructures, Nikon, Tokyo, Japan). The 2D Figure 2.
