Abstract We demonstrate a proof of concept for magnetically-driven 2D cells organization on superparamagnetic micromagnets fabricated by laser direct writing via two photon polymerization (LDW TPP) photopolymerizable composite. The composite consisted commercially available, biocompatible photopolymer (Ormocore) mixed with 4 mg/mL nanoparticles (MNPs). were designed in the shape squares 70 µm lateral dimension. To minimize role topographical cues cellular attachment, we microarrays similar...
We have designed, fabricated, and tested an amplitude diffractive optical element for generation of two-dimensional (2D) Airy beams. The design is based on a detour-phase computer-generated hologram. Using laser ablation metallic films, we obtained 2 mm×2 mm with pixel 5 μm×5 μm demonstrated fast, cheap, reliable fabrication process. This device can modulate 2D beams or it be used as UV lithography mask to fabricate series phase holograms higher energy efficiency. Tests according the premise...
This research is aimed at developing micrometer-level cone-shaped targets used in ultraintense laser-driven particle acceleration and improving the fabrication process quality of results. We developed a design software that based on single-pass spiral-like writing 3D structures to improve results lower time. Additive manufacturing two-photon polymerization represents chosen method. Targets have been investigated using electron microscopy x-ray microtomography. In this paper, several types...
Abstract The last several years witnessed increasingly rapid advances in applying biopolymers tissue engineering for the purposes of regenerative medicine. growing demand preparing materials with desired physical, biological and mechanical properties requires active investigations field engineering. Among wide variety biopolymers, chitosan proved to be an outstanding material due its properties, such as biocompatibility, biodegradability a range available fabrication technologies. present...
