    摘要: The invention provides systems and methods for manipulating, e.g., optimizing and controlling, biological systems, e.g., for eliciting a more desired biological response of biological sample, such as a tissue, organ, and/or a cell. In one aspect, systems and methods of the invention operate by efficiently searching through a large parametric space of stimuli and system parameters to manipulate, control, and optimize the response of biological samples sustained in the system, e.g., a bioreactor. In alternative aspects, systems include a device for sustaining cells or tissue samples, one or more actuators for stimulating the samples via biochemical, electromagnetic, thermal, mechanical, and/or optical stimulation, one or more sensors for measuring a biological response signal of the samples resulting from the stimulation of the sample. In one aspect, the systems and methods of the invention use at least one optimization algorithm to modify the actuator's control inputs for stimulation, responsive to the sensor's output of response signals. The compositions and methods of the invention can be used, e.g., to for systems optimization of any biological manufacturing or experimental system, e.g., bioreactors for proteins, e.g., therapeutic proteins, polypeptides or peptides for vaccines, and the like, small molecules (e.g., antibiotics), polysaccharides, lipids, and the like. Another use of the apparatus and methods includes combination drug therapy, e.g. optimal drug cocktail, directed cell proliferations and differentiations, e.g. in tissue engineering, e.g. neural progenitor cells differentiation, and discovery of key parameters in complex biological systems.

    摘要: The invention disclosed herein provides biosensors and methods which increase the sensitivity of assays of optically labelled molecules fluorescently tagged polypeptides and polynucleotides while decreasing the sample volume required for detection. By integrating reflective sidewalls into the receptacles used in such assays, the signal-to-noise ratio of the optical signal is increased significantly. Typically the receptacles are microchannels. In addition, the geometry of the receptacles can be controlled to further optimize the signal-to-noise ratio of the optical signal. The invention disclosed herein further provides methods and devices involving integrated electronics, wherein an element such as a diode, a transistor, an integrated circuit etc., is integrated with a bio-reactor/channel in order to facilitate the detection or fabrication of bio-materials.

    摘要: An apparatus for mixing fluids includes at least one noncircular orifice having unequal major and minor axis dimensions, with the major axis dimension being less than approximately 5 times the minor axis dimension. A first fluid is emitted from the orifice as a jet for mixing with another fluid in a region downstream of the orifice. The mixing region extends downstream a distance at least equal to the minor axis dimension, and then either terminates in a wall in the path of the jet or continues downstream to a total distance of at least approximately 3 times the minor axis dimension. The mixing region has a lateral width of at least 2(a+0.4x) in a direction parallel to the major axis and a lateral width of at least 2(b+0.4x) in a direction parallel to the minor axis, where a and b are one-half the major and minor axis dimensions, respectively, and x is the distance downstream of the orifice.

    摘要: An apparatus and method for forming a bubble within a microchannel of a microinjector to function as a valve mechanism between the chamber and manifold, that provides for a high resistance to liquid exiting the chamber through the manifold during fluid ejection through an orifice and that also provides a low resistance to refilling of liquid into the chamber after ejection of fluid and collapse of the bubble. This effectively minimizes cross talk between adjacent chambers and increases injection frequency of the microinjector. The formation of a second bubble within the chamber coalesces with a first formed bubble between the chamber and manifold to abruptly terminate the ejection of fluid, thereby eliminating satellite droplets.

    摘要: A micromachined hot-wire anemometer having fast response times and higher sensitivities than conventional hot-wire anemometers is provided by micromachining doped polysilicon wires carried on silicon supports cantilevered from a substrate including one or more insulating layers disposed between said substrate and supports. The micromachined polysilicon hot-wire anemometer is fabricated using surface micromachining techniques.A shear stress sensor is micromachined to define a thin diaphragm over a cavity defined in a substrate underlying the diaphragm. The cavity is evacuated, sealed, and a thermistor disposed over the diaphragm. The thermistor is thus thermally insulated from the substrate and provides a low profile shear stress sensor for measuring flow rates in boundary layers above a flow surface.
