Abstract:
The invention optical device comprising a self-processing photopolymer material configured to produce a variable two- or three- dimensional diffraction pattern when said material is illuminated by a light source. The invention provides a new material science and process technology which produces a serialisable anti-counterfeit optical device, based on a self-processing photopolymer.
Abstract:
A pressure sensitive holographic recording composition is described wherein the composition comprises diacetone acrylamide, glycerol and citric acid. The composition is capable of recording high diffraction efficiency reflection holograms.
Abstract:
A biosensor system for use in point-of-care applications and a method for fabricating sameThe present invention provides a biosensor system for use in point-of-care, POC, applications. The invention comprises a microfluidic channel for circulating biomolecules and a sensor adapted to receive the microfluidic channel and detect a plurality of different biomarkers from the biomolecules. The microfluidic channel and the sensor are formed on a photoreactive hybrid organic-inorganic sol-gel, PHOIS, resin.
Abstract:
The invention relates to a prognostic method of analyzing a biological sample from a cancer patient to predict his/her response to a specified modality of cancer treatment comprising the steps of: (a) performing spectroscopy on the biological sample to obtain a spectrum; (b) comparing the obtained spectrum with one or more spectra to calculate a probability of a response to the specified modality of cancer treatment by the cancer patient.
Abstract:
This present application relates generally to the science of fluid flow measurement and provides a multi-directional fluid velocity measurement device (FVMD) employing a plurality of pitot tubes arranged in a 3D configuration and extending from a spherical main body in which measurement sensors are provided.
Abstract:
A method of performing a spectroscopy process on a fixed biological sample is described. The method comprises the steps of: (i) treating the fixed biological material to cause oxidation of haemoglobin present in the fixed biological material, and (ii) performing spectroscopy on the treated fixed biological sample. The method is particularly suitable for cervical sample preparation for reduced variability in Raman spectroscopy.
Abstract:
A method for producing a multi-layer anodic coating on a metal is described. The method comprises the steps of (i) placing the metal in a first electrolytic solution and applying a current to form a first anodic layer having a barrier region; (ii) reducing the applied current to cause a reduction in thickness of the barrier region; and (iii) placing the metal in a second electrolytic solution and applying a current to form a second anodic layer.
Abstract:
A process for the preparation of an antimicrobial coating solution is described. The process comprises the steps of: (i) mixing a chelating agent with titanium alkoxide and fluoroacetic acid; and (ii) adding an aqueous solution to the mixture from step (i). The antimicrobial coating described is visible light activated. The coating is applied to surfaces and then heat treated to form a transparent layer on the surface. This is particularly advantageous where the surface is glass.
