Tissues formed by cells seeded in hydrogels are used for biotechnology, cell-based assays, and tissue engineering. We have previously presented a cell-micropatterning technique that localizes live cells within hydrogels using dielectrophoretic (DEP) forces, and have demonstrated the ability to modulate tissue function through the control of microscale cell architecture. In this study, we developed...
In this study, we report a newly developed three-dimensional (3D) biological printer using non-contact, electromechanical microvalves with a nozzle diameter of 150 mum. To control and utilize this printer for life science applications, we developed an easy-to-use control software with a graphic user interface (GUI). First, using the printer, we tested the viability of dispensed mammalian cells after...
dasiaBrain on Chippsila technologies based on two-dimensional in-vitro neural cultures have attracted much interest in both basic and applied neuroscience over the past two decades. Extending this technology towards more brain-like three-dimensional geometries while maintaining the ability to record and/or control the neural activity is an important neural engineering challenge. We have developed...
Today, one of the limitations associated with cartilage grafting is the lack of bonding between the implanted materials and the natural tissue. Helical rosette nanotubes (HRNs) are novel biomimetic self-assembled supramolecular structures whose basic building blocks are DNA base-pairs, which can solidify into a viscous gel at body temperatures in short periods of time. HRNs are similar in size to...
We wish to form polymeric bioreactors with interconnected microfluidic channels between walls or struts that have cells embedded or attached to the surface. A Rapid Prototyping (RP) fabrication technique is employed, using blue light curing to crosslink water-soluble monomers to hydrogels. The 3D writing is carried out by a computer-controlled syringe system that extrudes a fine line of monomer. The...
