The present invention relates firstly to a method for reproducing a stem cell niche of an organism. The invention further relates to a reproduction of a stem cell niche of an organism. According to the invention, an image of a tissue of an organism is generated, which tissue comprises at least one stem cell niche. The image is filtered in order to obtain a structural pattern of the imaged stem cell niche. In a further step, a lithographic mask is generated from the structural pattern. According to the invention, a starting material of a substrate is structured by means of indirect or direct application of the lithographic mask, whereby a structured substrate is obtained which represents the reproduction of the imaged stem cell niche of the organism. The reproduction can be characterised as biolithomorphic.

A diffractive security device is disclosed including at least a first diffractive structure defined in a carrier layer. The first diffractive structure is an on-axis diffractive zone plate structure of a continuously curved surface configured such that when the device is illuminated by on-axis light a first diffraction pattern generated by the first diffractive structure can be viewed from at least a first side of the device at substantially all viewing angles, the first diffraction pattern exhibiting a reference point or reference line relative to which other features of the first diffraction pattern appear to move when the viewing angle is changed.

A method and surface micro patterned stamp for patterning image correlation test specimens is disclosed. The stamp may be formed and applied to the surface of structural components and laboratory test specimens in a repeatable fashion while reducing requisite infrastructure and time. The resulting test specimen incorporating the surface micro stamped pattern is also disclosed.

Method for manufacturing a horology component, including manufacturing (E1) a first structure (10) from a first photosensitive resin (31) having at least one layer of photosensitive resin having a first pattern obtained by polymerizing the first photosensitive resin by irradiation through at least one mask (4), then developing the first photosensitive resin; and transforming (E2) the first structure (10) into a second structure (1) by structuring at least one surface of the first structure by the addition of a second photosensitive resin (32) to the at least one surface, the second structure (1) being intended to at least partially form a manufacturing mold for the horology component.
