A method for fabricating waveguides comprising nano-apertures for illumination of sub-resolution exposures is presented. In particular, the end of a waveguide, such as an optical fiber, is coated with a material, such as an electrically conducting metal or a semiconductor. This material is then selectively removed through the process of ion milling, creating an aperture in the material at the end of the waveguide. Under normal conditions, if the aperture is smaller than the wavelength of light in the waveguide, there is little or no transmission through the aperture. However, with the appropriate selection of materials and aperture geometry, for example a metallic conducting coating and sub-wavelength “C-shaped” or “bow-tie” aperture, enhancement of transmission of light through the aperture can be achieved, allowing effective illumination of sub-resolution spots using the ion-milled aperture. This can be used in a nanolithography system incorporating waveguide illuminators as well.

Provided is a Michael addition product prepared from a multifunctional acryl monomer having multiple hydroxyl groups allowing introduction of acryl functional groups, as a Michael acceptor, and a Michael donor. The Michael addition product is a novel multifunctional compound having an oligomer and a photoinitiator moiety in the molecule.

The invention concerns methods of quantification of an analyte, A, in a test sample by means of a single immunochromatographic device, such as a lateral flow device (LFD). One method comprises the steps of: a) mixing a determined amount of said test sample with a determined amount of a quantification agent, QA1, said QA1 being capable of binding specifically and simultaneously both to an immobilized binding partner and to A, thus obtaining a mixture wherein the amount of A in said test sample is reflected by the ratio of the concentration of A-QA1 complex formed to the concentration of free QA1 in said mixture; b) applying a determined volume of said mixture to said device equipped with a test band in which said binding partner of the QA1 is immobilized, so that A-QA1 complex and free QA1 are immobilized at said test band in a ratio that relates to their concentration ratio in the mixture applied, said volume of mixture being determined to provide a total amount of A-QA1 complex and free QA1 capable of sufficiently saturating the immobilized binding partner in said test band; c) measuring the amount of either said A-QA1 complex or said free QA1 immobilized at the test band by means of an appropriately chosen detection procedure; d) comparing the result obtained from the test sample with the results obtained from calibration samples containing known or allocated amounts of A and thus determining the amount of A in said test sample. By including the two procedural stages a) and b) this greatly diminish or eliminate the sources of run-to-run variation.
