    摘要: Described herein are microfluidic modules and methods for making the same, wherein the microfluidic modules include a substrate comprising at least one ether-based, aliphatic polyurethane, and at least one fluidic element disposed therein. The ether-based aliphatic polyurethane can be either the substrate of the microfluidic modules or a coating of another substrate material, such that at least a portion of the ether-based, aliphatic polyurethane is in fluid communication. In one embodiment, the ether-based, aliphatic polyurethane includes dicyclohexylmethane-4,4′-diisocyanate. As the ether-based aliphatic polyurethane can decrease absorption of molecules, e.g., hydrophobic molecules, in such microfluidic modules, the microfluidic modules described herein can be used in various applications such as drug screening and fluorescent microscopy.

    摘要: The present invention is a method of dehydroxylating a silica surface that is hydroxylated having the steps of exposing the silica surface separately to a silicon organic compound and a dehydroxylating gas. Exposure to the silicon organic compound can be in liquid, gas or solution phase, and exposure to a dehydroxylating gas is typically at elevated temperatures. In one embodiment, the improvement of the dehydroxylation procedure is the repetition of the soaking and dehydroxylating gas exposure. In another embodiment, the improvement is the use of an inert gas that is substantially free of hydrogen. In yet another embodiment, the present invention is the combination of the two-step dehydroxylation method with a surfactant templating method of making a mesoporous film.

    摘要: A system has been constructed that recapitulate the features of a capillary bed through normal human tissue. The system facilitates perfusion of three-dimensional (3D) cell monocultures and heterotypic cell co-cultures at the length scale of the capillary bed. A major feature is that the system can be utilized within a “multiwell plate” format amenable to high-throughput assays compatible with the type of robotics commonly used in pharmaceutical development. The system provides a means to conduct assays for toxicology and metabolism and as a model for human diseases such as hepatic diseases, including hepatitis, exposure-related pathologies, and cancer. Cancer applications include primary liver cancer as well as metastases. The system can also be used as a means of testing gene therapy approaches for treating disease and inborn genetic defects.

    摘要: Systems including (1) a micromatrix and perfusion assembly suitable for seeding and attachment of cells within the matrix and for morphogenesis of seeded cells into complex, hierarchical tissue or organ structures, wherein the matrix includes channels or vessels through which culture medium, oxygen, or other nutrient or body fluids can be perfused while controlling gradients of nutrients and exogenous metabolites throughout the perfusion path independently of perfusion rate, and (2) sensor means for detecting changes in either cells within the matrix or in materials exposed to the cells, have been developed. Methods for making the micromatrices include micromachining, micromolding, embossing, laser drilling, and electro deposition machining. Cells can be of one or more types, either differentiated or undifferentiated. In a preferred embodiment, the matrix is seeded with a mixture of cells including endothelial cells which will line the channels to form “blood vessels”, and at least one type of parenchymal cells, such as hepatocytes, pancreatic cells, or other organ cells. The system can be used to screen materials for an effect on the cells, for an effect of the cells on the materials (for example, in a manner equivalent to tissue metabolism of a drug), or to test a material on a biological that must first infect cells or tissues, such as viruses. The apparatus also can be used to provide a physiological environment for expansion of stem cells, or for enabling gene therapy in vitro.

    摘要: A microfluidic device of a diagnostic and detection system includes an inlet port connected by one or more microchannels to an outlet port and includes a capture and visualization chamber (CVC) connected to at least one microchannel. A fluid to be analyzed can be mixed with magnetic microbeads that have an affinity to become bound to target components, such as pathogens in the fluid. The fluid including the magnetically bound target components can be injected through the microfluidic device. Magnetic field gradient, such as provided by permanent or electro-magnets, can be applied to the fluid and the magnetically bound target components flowing through the microfluidic device to cause the magnetically bound target components to migrate into the (CVC) and become separated from the fluid. The magnetically bound target components can be analyzed and tested using various techniques to detect the presence of specific organic and inorganic materials, such as pathogens in bio-fluids and contamination in liquid food sources (e.g. water). The device and method provide a system for rapidly detecting pathogens and contamination in relatively small fluid samples.

    摘要: A dialysis like therapeutic (DLT) device is provided. The DLT device includes at least one source channel connected at least one collection channels by one or more transfer channels. Fluid contacting surface of the channels can be an anti-fouling surface such as slippery liquid-infused porous surface (SLIPS). Fluids can be flown at high flow rates through the channels. The target components of the source fluid can be magnetic or bound to magnetic particles using an affinity molecule. A source fluid containing magnetically bound target components can be pumped through the source channel of the microfluidic device. A magnetic field gradient can be applied to the source fluid in the source channel causing the magnetically bound target components to migrate through the transfer channel into the collection channel. The collection channel can include a collection fluid to flush the target components out of the collection channel. The target components can be subsequently analyzed for detection and diagnosis. The source channel and the collection channels of the microfluidic device are analogous to the splenic arterioles and venules, respectively; the transfer channels mimic the vascular sinusoids of the spleen where opsonized particles are retained. Thus, the device acts as a dialysis like therapeutic device by combining fluidics and magnetics.
