    摘要: 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.

    摘要: 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. The invention further provides method of fabricating hOR17-4 olfactory receptor.

    摘要: A method for synthesizing long DNA constructs from oligonucleotide precursors directly within a microfluidic device uses several oligonucleotides at once. A precursor mix containing at least two oligonucleotide precursors with at least partial base complementarity is introduced into an input of a microfluidic chip and at least one cycle of at least one gene synthesis protocol is applied to fabricate a DNA construct containing the sequence of at least two oligonucleotide precursors. A method for the synthesis of a modified DNA construct includes electroporating at least one oligonucleotide encoding for at least one point mutation and having homology with at least one DNA region of a target cell into the target cell and incorporating the oligonucleotide into the target cell DNA through the action of recombination protein beta or a recombination protein beta functional homolog.
