Two-photon polymerization (2PP) is a cutting-edge technique for fabricating precise micro- and nanostructures, with applications in photonics, biomedical engineering, and micro-optics. A critical factor influencing the optical performance of 2PP-fabricated structures is the refractive index (RI) of the printed parts. This study analyzes the refractive indices of three resins developed by UpNano GmbH. Using a […]
Since the inception of 3D printing in the 1980s, there have been remarkable advancements that have given rise to a wide array of technologies. In the field of bioprinting, many of these technologies are being leveraged to embed living cells into precisely defined 3D structures. Droplet- and extrusion-based bioprinting, two of the earliest techniques, have […]
Polydimethylsiloxane (PDMS) has been the material of choice for microfluidic applications in cell biology for many years, with recent advances encompassing nano-scaffolds and surface modifications to enhance cell-surface interactions at nano-scale. However, PDMS has not previously been amenable to applications which require complex geometries in three dimensions for cell culture device fabrication in the absence […]
