“…These structures give rise to diverse functions ranging from mechanical strengthening (11) and directional adhesion (12,13) to superhydrophobicity (14) and structural colors (15), thus inspiring researchers to devote their efforts to mimic these multifunctional structures for decades. Many top-down fabrication approaches such as photolithography together with deep dry etching (16), replica molding (14, 17), multibeam laser interference lithography (18,19), and electron-beam lithography (20) have been used in combination with capillary force self-assembly to produce hierarchical structures.…”

Capillary force is often regarded as detrimental because it may cause undesired distortion or even destruction to micro/nanostructures during a fabrication process, and thus many efforts have been made to eliminate its negative effects. From a different perspective, capillary force can be artfully used to construct specific complex architectures. Here, we propose a laser printing capillaryassisted self-assembly strategy for fabricating regular periodic structures. Microscale pillars are first produced by localized femtosecond laser polymerization and are subsequently assembled into periodic hierarchical architectures with the assistance of controlled capillary forces in an evaporating liquid. Spatial arrangements, pillar heights, and evaporation processes are readily tuned to achieve designable ordered assemblies with various geometries. Reversibility of the assembly is also revealed by breaking the balance between the intermolecular force and the elastic standing force. We further demonstrate the functionality of the hierarchical structures as a nontrivial tool for the selective trapping and releasing of microparticles, opening up a potential for the development of in situ transportation systems for microobjects.laser printing | capillary force | self-assembly | hierarchical structures | microobject trapping P eople learn from daily life experience that individual filaments can coalesce, as with wet hairs or paintbrushes pulling out of paint. Analogs of this elastocapillary coalescence exist and are often amplified in micro/nanoelectromechanical system manufacturing processes because the capillary force tends to dominate over the standing force that needs to be overcome for coalescence when the scale is reduced (1, 2). When one aims to create slender structures, the dominant capillary force drives them to collapse, cluster, or be completely destroyed. Some efforts such as adopting a supercritical-point dryer (3, 4) have been made to eliminate these unwanted behaviors when fabricating high-aspect-ratio structures. However, from another point of view, the capillary-driven bottom-up self-assembly can be exploited as a valuable tool to construct complex architectures. Compared with other driving forces for self-assembly such as magnetism (5), electrostatic force (6), and gravity (7), capillary force self-assembly features the advantage of simplicity, low cost, scalability, and tunability.The desire for scalable and cost-effective self-assembly schemes comes from observations of the natural world, where self-assembled filamentous structures with mechanical compliance at the microscopic and mesoscopic scale are ubiquitous and include, to name a few, actin bundles (8), gecko feet hairs (9), and Salvinia leaf (10). These structures give rise to diverse functions ranging from mechanical strengthening (11) and directional adhesion (12, 13) to superhydrophobicity (14) and structural colors (15), thus inspiring researchers to devote their efforts to mimic these multifunctional structures for decades.

Abstract:We present the design, construction, and characterization of a multiphoton microscope that uses reflective elements for beam shaping and steering. This compact all reflective design removes the adverse effects of dispersion on laser pulse broadening as well as chromatic aberration in the focusing of broadband and multicolored laser sources. The design of this system is discussed in detail, including aberrations analysis via ray-tracing simulation and opto-mechanical design. The resolution of this mirror based all-reflective microscope is characterized using fluorescent microbeads. The performance of the system at multiple wavelengths is investigated along with some potential multiphoton imaging and writing applications. Nelson, and S.

“…Numerous treatments such as O 2 , C 2 F 2 , SF 6 , CF 4 , SiCl 4 , CCl 4 or mixture of the gases have been practical on PDMS surface to improve its hydrophobic properties. Besides, PDMS as a substrate or a structural material also growing according to the variety of design choices by post processing methods such as etching, coating, polishing, deposition and surface modification [1][2][3][4][5][6][7][8][9][10][11][12].

Roughness dependence of optical coefficient polarization on pixels’ diffractive elements by stretching technique

In this research work, two polydimethylsiloxane diffractive elements (DEs) of 3 mm thickness under the same conditions are fabricated using molding technique and one DEs rough surface is modified by plasma O 2 treatment in a vacuum chamber. The effects of both rough surface DEs on the structure and optical properties are investigated by atomic force microscope, white light interferometer and FDTD simulated, which indicates that the plasma O 2 treatment induces the formation of nanostructures and decreases the surface roughness up to some roughness level. The optical transmittance, reflectance, absorption, Raman scattering spectra and optical coefficient measurement provides better results to polymer DEs, to be used as replica, efficient and cost effective. Furthermore, the stretchable technology is applied on both DEs, which provides results towards diffraction grating and thus, have widespread applications in optical transmission and reflection domain such as measuring, imaging, coding and solar energy.
