Laser photofabrication of cell-containing hydrogel constructs.
The two-photon polymerization (2PP) of photosensitive gelatin in the presence of living cells is reported. The 2PP technique is based on the localized cross-linking of photopolymers induced by femtosecond laser pulses. The availability of water-soluble photoinitiators (PI) suitable for 2PP is crucial for applying this method to cell-containing materials. Novel PIs developed by our group allow 2...
متن کامل3D-printed microfluidic chips with patterned, cell-laden hydrogel constructs.
Three-dimensional (3D) printing offers potential to fabricate high-throughput and low-cost fabrication of microfluidic devices as a promising alternative to traditional techniques which enables efficient design iterations in the development stage. In this study, we demonstrate a single-step fabrication of a 3D transparent microfluidic chip using two alternative techniques: a stereolithography-b...
متن کاملLaser-targeted photofabrication of gold nanoparticles inside cells.
Nanoparticle manipulation is of increasing interest, since they can report single molecule-level measurements of the cellular environment. Until now, however, intracellular nanoparticle locations have been essentially uncontrollable. Here we show that by infusing a gold ion solution, focused laser light-induced photoreduction allows in situ fabrication of gold nanoparticles at precise locations...
متن کاملMagnetic assembly of microfluidic spun alginate microfibers for fabricating three-dimensional cell-laden hydrogel constructs
microchannels. Interestingly, this impulse can achieve to temporarily cease the spinning process. Moreover, an optimized magnetic assembly is achieved by considering both the assembling area on a ring magnet and the MNPs concentration in microfibers. After the test of cell survival, a high cell viability of 97.2 % can be confirmed in assembled structures, which indicates that our method allows ...
متن کاملIn Vivo Chondrogenesis in 3D Bioprinted Human Cell-laden Hydrogel Constructs
BACKGROUND The three-dimensional (3D) bioprinting technology allows creation of 3D constructs in a layer-by-layer fashion utilizing biologically relevant materials such as biopolymers and cells. The aim of this study is to investigate the use of 3D bioprinting in a clinically relevant setting to evaluate the potential of this technique for in vivo chondrogenesis. METHODS Thirty-six nude mice ...
