Abstract: Methods and apparatus for concentrating light into a specified focal volume and for collecting light from a specified volume. Incident light is coupled through a plurality of successive transmissive asymmetric microstructure elements. The succession of transmissive asymmetric microstructure elements may be designed by representing an electromagnetic field as a linear combination of eigenmodes of one of the succession of transmissive asymmetric microstructure elements. The asymmetric microstructure elements are represented as a plurality of mesh lattice units and eigenmode solutions to Maxwell's equations are obtained for each mesh lattice unit subject to consistent boundary conditions. S-matrix formalism is employed to calculate a field output and weighting coefficients for the eigenmodes are selected to achieve a specified set of field output characteristics.

Abstract: This invention relates to an apparatus and a method for measuring whether organic matter is present or whether or not organisms (cells or tissue) are alive using infrared absorption spectroscopic analysis. The measurement apparatus of the invention includes an infrared light source for radiating infrared rays on a sample, an infrared detection unit for detecting the infrared rays transmitted or reflected from the sample, and a determination unit for identifying an amide infrared absorption peak of the sample using the detected infrared rays and for determining whether organic matter is present or whether organisms are alive or not in the sample using the identified amide infrared absorption peak. In this invention, a reagent is not used, simple measurement is performed, quantification is feasible, and the presence or absence of cells or tissues and changes in the life and death can be consecutively measured for the same sample.

Abstract: This disclosure concerns photonics and in particular the addressing of individual targets in solids. In aspect one there is provided a device comprising a solid substrate with one or more atomic scale targets in the substrate. A laser light is focused on a region of the substrate that contains a single target to selectively cause photoionization of the target. A charge sensor with sub-electron charge sensitivity is focussed on measuring the charge in the region of the substrate that contains a single target. In use, the device operates such that the laser is turned on to cause photoionization of the target, and the charge sensor detects the change in charge in the region of the substrate that contains the single target. In another aspect is the method for optically investigating individual nuclear spin states of single atoms by investigating both the Zeeman effect and the hyperfine interaction of the single atoms.

Abstract: Apparatus, methods, and other embodiments associated with NMR fingerprinting are described. One example NMR apparatus includes an NMR logic configured to repetitively and variably sample a (k, t, E) space associated with an object to acquire a set of NMR signals. Members of the set of NMR signals are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The varying parameters may include flip angle, echo time, RF amplitude, and other parameters. The NMR apparatus may also include a signal logic configured to produce an NMR signal evolution from the NMR signals, a matching logic configured to compare a signal evolution to a known, simulated or predicted signal evolution, and a characterization logic configured to characterize a resonant species in the object as a result of the signal evolution comparisons.

Abstract: The push button operated rodent restrainer is designed to hold a rodent in position to access their tail veins during tail vein injections or for extraction of blood. The assembly includes a base rectangular platform supporting two hinged, transparent half-cylinders. When the assembly is closed, the half-cylinders form a closed tube, which restrains the rodent. The half-cylinders are made of transparent plastic to allow laboratory staff to observe the rodent. The tube facilitates restraining the rodent and includes a longitudinal slit to allow proper ventilation while the rodent is restrained. One end of the closed tube has a slot, which allows the rodent's tail to protrude outside the tube for access to the tail. A push button mounted on a resilient lever is connected to the tube halves such that when the push button is depressed, the tube opens, and when the push button is released, the tube closes.
