Abstract: In exemplary implementations, transplantation of nucleic acids into cells occurs in microfluidic chambers. The nucleic acids may be large nucleic acid molecules with more than 100 kbp. In some cases, the microfluidic chambers have only one orifice that opens to a flow channel. In some cases, flow through a microfluidic chamber temporarily ceases due to closing one or more valves. Transplantation occurs during a period in which the contents of the chambers are shielded from shear forces. Diffusion, centrifugation, suction from a vacuum channel, or dead-end loading may be used to move cells or buffers into the chambers.

Abstract: One or more light sources may apply stimuli to a colony of organisms. The stimuli may include visible and non-visible light. The stimuli, taken together, may tend to favor survival of organisms that are adapted to perform photosynthesis which involves absorbing energy from infrared or ultraviolet light. In some cases, the set of stimuli may include illuminating the entire colony of organisms with green light, illuminating only a first portion of the colony with pulsed ultraviolet light, and illuminating only a second portion of the colony with pulsed infrared light.

Abstract: The invention provides a bio-sensing nanodevice comprising: a stabilized biologically-derived G-protein coupled receptor—the olfactory receptor—on a support, a real time receptor-ligand binding detection method, an odorant delivery system and an odorant recognition program. The biologically-derived G-protein coupled receptor can be stabilized on nanotechnology using surfactant peptide. The said nanodevice provides a greater surface area for better precision and sensitivity to odorant detection. The invention further provides a microfluidic chip containing a stabilized biologically-derived G-protein coupled receptor—the olfactory receptor—immobilized on a support, and arranged in at least two dimensional microarray system. The invention also provides a method of delivering odorant comprising the step of manipulating the bubbles in complex microfluidic networks wherein the bubbles travel in a microfluidic channel carrying a variety of gas samples to a precise location on a chip.

Abstract: In illustrative implementations of this invention, microfluidic perfusion tubing is easily and precisely inserted into a microfluidic device. The tubing is inserted in a manner that aligns one or more holes in the perfusion tubing with one or more channels in the microfluidic device. For example, a hole in the tip of a perfusion tube may open into a channel in the microfluidic device. Or, multiple holes in a tube may open into different channels in a microfluidic device. The system may include a microfluidic device, two or more couplers, and a support frame. The microfluidic device may be inserted into a recessed region of the support frame, and the couplers may be attached to the support frame. The effect of doing so is to fix the position of the components relative to each other, and to precisely align holes in the tubes with channels in the microfluidic device.

Abstract: Methods, systems, and apparatus implementing a generalizable self-calibrating protocol coupled with machine learning algorithms in an exemplary setting of classifying perceptual states as corresponding to the experience of perceptually opposite mental states (including pain or no pain) are disclosed. An embodiment presented represents inexpensive, commercially available, wearable EEG sensors providing sufficient data fidelity to robustly differentiate the two perceptually opposite states. Low-computational overhead machine learning algorithms that can be run on a mobile platform can be used to find the most efficient feature handles to classify perceptual states as self-calibrated by the user. The invention is generalizable to states beyond just pain and pave the way towards creating EEG NFB applications targeting arbitrary, self-calibrated perceptual states in at-home and wearable settings.

Abstract: In exemplary implementations of this invention, an electronic olfactor determines whether a scent being tested matches the scent of a positive control. The electronic olfactor can perform this scent matching even in a changing olfactory environment, and even if the positive control scent is a combination of hundreds or thousands of different odorants. No prior training is needed, and no attempt is made to identify a single odorant that is unambiguously responsible for a scent. Instead, a computer compares the total scent pattern of a positive control sample with the total scent pattern of a test sample, across a sweep of many permutations of electrical inputs to scent sensors, to try to find any condition under which the total scent patterns do not match. If such a condition cannot be found, then the computer declares a match between the test and target scents.

Abstract: A trans-disciplinary system for cell-free biosynthesis includes a cell-free transcription-translation (TX-TL) tool and modular, generalizable microfluidic architectures. Both components of the system are independently functional and are combinable into a cell-free biosynthesis platform. In the first component, modular plasmid libraries are used to program bacterial cell-free TX-TL systems. Each plasmid holds one gene or operon, and all the genes are controlled by the same promoter, so that the stoichiometry of enzyme synthesis is determined by the stoichiometry of plasmids in the reaction. In the second part, in order to facilitate high throughput mixing and matching of gene units from the modular plasmid libraries, a modular, reconfigurable, flexible, and scalable microfluidic architecture is employed.

Abstract: Methods and apparatus for determining water content in a bulk heterogeneous material using electromagnetic radiation. A radiation source and a radiation receiver are positioned such that the material to be measured is located between them. As the radiation signal is transmitted from the source to the receiver, the signal experiences a path loss due, at least in part to the presence of the material located between the source and the receiver. The path loss in the transmitted signal, when recorded over time may be used to determine the water content of the material.
