  • A METHOD OF FORMING A THIN FILM THROUGH-HOLE MEMBRANE
    Publication number: 20190022595
    Abstract: There is provided a method of forming a thin film through-hole membrane comprising: providing a patterning structure, the patterning structure comprising a patterning substrate, a sacrificial layer and a thin film; imprinting the thin film with a patterned mold to form a thin-film through-hole membrane; and contacting the patterning structure with water to dissolve the sacrificial layer, thereby releasing the thin film through-hole membrane from the patterning structure. There is also provided a hierarchical membrane comprising the thin film through-hole membrane prepared from the method.

  • System and method of edge-illumination microscopy
    Patent number: 10031326
    Abstract: According to one aspect, the invention concerns a method for microscopy of a thick sample arranged on a sample support, with edge-illumination of the sample. The method comprises, in particular, emitting at least one illumination beam (1), forming, from the illumination beam, an illumination surface, focusing the illumination surface in the sample by means of a microscope lens (120) and deflecting the illumination surface originating from the microscope lens, in order to form a transverse illumination surface, located in a plane substantially perpendicular to the optical axis of the microscope lens.

  • Method for detecting a circularized DNA, and use of said method for detecting mutations
    Patent number: 9499859
    Abstract: The present invention relates to a method for detecting a circularized single-stranded DNA by means of the isothermal hyperbranched rolling circle amplification technique, in which the primers used comprise a detectable barcode sequence and, optionally, a spacer which blocks polymerization by DNA polymerase. The present invention also relates to the use of said method for detecting a genetic polymorphism of one or more base pair(s).
