Abstract:
A printed tissue construct comprises one or more tissue patterns, where each tissue pattern comprises a plurality of viable cells of one or more predetermined cell types. A network of vascular channels interpenetrates the one or more tissue patterns. An extracellular matrix composition at least partially surrounds the one or more tissue patterns and the network of vascular channels.
Abstract:
Methods of making a spheroid are provided whereby a suspension is first produced including one or more biologically-relevant materials dispersed within a biocompatible medium. A droplet of the suspension is then bioprinted into a salt solution by bringing the droplet into contact with a surface of the salt solution in a controlled manner to reproducibly yield a spheroid containing a desired size and a desired amount of biologically-relevant materials.

Abstract:
A series of reactor tubes can be employed to remove a biofilm from a growth medium. Each reactor tube can contain a cathode comprised of a blend of transition metal oxides. As the growth medium is passed through the series of reactor tubes, a specific voltage and amperage can be applied to the reactor tubes to cause the biofilm to aggregate without damaging the algae. The aggregated biofilm can then be easily removed from the growth medium.
Abstract:
The present invention is generally directed to a system for producing an algae biomass and wastewater that have reduced concentrations of contaminants. The algae and wastewater treated by the system of the present invention can be combined in a heterotrophic growth system in which the growth of the algae is increased due to the reduced concentration of contaminants. The algae grown in this manner also has a longer shelf life due to the lack of contaminants within the harvested algae.
Abstract:
A microfluidic system for generating compartmentalized microenvironments of tissues and organs in vitro and for independently perfusing the compartments. A microfluidic device that includes at least a first perfusion path and a second separate perfusion path. The microfluidic device also has a chamber containing a matrix, where the matrix surrounds at least one void whose lumen is in fluidic connection exclusively with the first perfusion path, where the at least one void can be populated with at least one cell type in such way that the cells are in direct contact with the matrix and the matrix is in fluidic connection exclusively with the second separate perfusion path.
Abstract:
An applied electrical field effects the harvesting of algae from a growth medium through increased interface potential between solvent and solute and the use of micron-sized bubbles of hydrogen and oxygen gas. The process and method makes use of strategically placed bipolar electrode plates that generate hydrogen and oxygen gas. Micro bubbles of the gas flocculate the biomass out of solution concurrently clarifying the water for re-use in an algae growth system. The flocked algae can then be processed for use in applications which require a chemical-free and dewatered product such as required for bio-fuels, pharmaceuticals or food.
Abstract:
A method and apparatus are provided for constructing tissue from cells or other objects by application of temporally and spatially controlled electric fields. Electric field applicators expose a substrate (32) to the electric field controlled to affect the processing medium (28) to achieve a processing effect on the construction of tissue on the substrate (32). Electrical bias is selected to interact with dipole properties of the medium (28) to control the movement of suspended dielectrophoretic cells or other particles in the medium (28) or at the substrate (32). The motion of suspended particles may be affected to cause suspended particles of different properties to follow different paths in the processing medium (28), which may be used to cause the suspended particles to be sorted. The processing medium (28) and electrical bias may be selected to affect the structure, or orientation, of one or more layers on the substrate (32).
Abstract:
Systems, devices, and methods for restraining a micro-object are provided. In one aspect, a micro-object restraint device is provided having a micro-barrier structure coupled to a support substrate, where the micro-barrier structure has two micro-object holding regions. Each micro-object holding region includes a micro-object receiving opening defined in the micro-barrier structure, a micro-object impeding opening at an internal region of the micro-barrier structure, and at least two contact points positioned adjacent to the micro-object impeding opening and oriented to contact and impede a micro-object at the micro-object opening. The two micro-object holding regions abut one another and the micro-object openings from the two micro-object holding regions are continuous.
