Transparent photobioreactor for scale-up culture of photosynthetic organisms and method for fabricating the same
The present invention relates to a large-scale photosynthetic bioreactor in which transparent photobioreactors including a baffle are connected in parallel or in series by an adhesive element so that the reactor volume can be easily scaled up for scale-up culture of photosynthetic organisms, and to a fabrication method thereof. The large-scale photosynthetic bioreactor according to the present invention makes it possible to culture a larger amount of microalgae than a conventional photobioreactor in the same area. In addition, it has high light transmittance, produces a large amount of biomass per unit area due to smooth mixing, and has a significant effect of reducing carbon dioxide. Furthermore, the present invention has an advantage in that the number of photosynthetic bioreactors required to culture the same scale of photosynthetic organisms is significantly smaller than that in a conventional process for culture of photosynthetic organisms, and thus the operating costs can be reduced.

Pumpless platform for high-throughput dynamic multicellular culture and chemosensitivity evaluation
The described invention provides an ex vivo dynamic multiple myeloma cancer niche contained in a pumpless perfusion culture device. The dynamic multiple myeloma cancer niche includes (a) a three-dimensional tissue construct containing a dynamic ex vivo bone marrow niche, which contains a mineralized bone-like tissue containing viable osteoblasts self-organized into cohesive multiple cell layers and an extracellular matrix secreted by the viable adherent osteoblasts; and a microenvironment dynamically perfused by nutrients and dissolved gas molecules; and (b) human myeloma cells seeded from a biospecimen composition comprising mononuclear cells and the multiple myeloma cells. The human myeloma cells are in contact with osteoblasts of the bone marrow niche, and the viability of the human myeloma cells is maintained by the multiple myeloma cancer niche.

A device for growing microorganisms. The device includes a body member comprising a self-supporting, water-proof substrate having upper and lower surfaces; a hydrophobic spacer element adhered to the upper surface of the substrate forming side walls to retain a predetermined amount of liquid in contact with the substrate, wherein the hydrophobic spacer element has a hole therein; a fluid control film in the hole of the hydrophobic spacer element; a cover sheet having an inner-facing surface and an outer-facing surface, the cover sheet adhered to at least a portion of the body member; and a substantially dry, first microbial growth nutrient composition disposed on a portion of the inner surface of the cover sheet; a first adhesive composition adhered to the first microbial growth nutrient composition; and a cold-water-soluble first hydrogel-forming composition adhered to the first adhesive composition.
GLASS COMPOSITE MATERIAL AND METHOD FOR PRODUCING
A glass composite is provided that has a first and second glass element, each having a first surface, and a first coupling agent layer having a first and second silane coupling agent. The first coupling agent layer has covalent bonds between the first and second silane coupling agents. The first and second silane coupling agents are covalently bonded to the first surface of the first and second glass elements, respectively. The first and second glass elements are irreversibly connected by the first coupling agent layer. Such a glass composite is made by bonding the first surface of the first and second glass elements to the first and second silane coupling agents, respectively, and contacting both first surfaces with each other to cause the first and second silane coupling agents thereon to covalently bond so that the first and second glass elements are irreversibly connected.
