    • New emerging technologies such as nanoimprint lithography (NIL) offers the biosensor research community the possibility to fabricate low-cost biodevices having nanometer dimensions. Such nanosized devices can be applied as biosensors where new functions might emerge due to the nanoscale dimensions. In this paper we will discuss various nanolithography methods as well as the benefits of going to the nanoscale for biosensor applications. We will also show results from mixed NIL and UV-lithography for fabrication of interdigitated nanobiosensor electrodes on up to 6'' large Si wafers. The electrode and inter-electrode distances were 100 nm wide over a total area of 200 μm×200 μm. We will also show the obtained enhanced efficiency of redox-recycling when utilizing such nanoscaled biosensors

  • Nanowire arrays defined by nanoimprint lithography
  • 2004
  • Ingår i: Nano Letters. - : American Chemical Society (ACS). - 1530-6992 .- 1530-6984. ; 4:4, s. 699-702

    • We demonstrate the use of nanoimprint lithography to define arrays of vertical InP nanowires. Each nanowire is individually seeded from a catalyzing gold particle and then grown via vapor-liquid-solid growth in a metal-organic vapor phase epitaxy system. The diameter and position of each nanowire can be controlled to create engineered arrays, demonstrated with a hexagonal photonic crystal pattern. This combination of nanoimprint and self-assembly of nanostructures is attractive for photonics and electronics, as well as in life sciences.

  • A comparison of thermally and photochemically cross-linked polymers for nanoimprinting
  • 2003
  • Ingår i: Microelectronic Engineering. - 1873-5568. ; 67-8, s. 266-273
  • Tidskriftsartikel (refereegranskat)abstract
    • The characteristics and benefits of two types of cross-linking prepolymers with low glass transition temperature (T-g) for nanoimprinting are reported. They are soluble in organic solvents and their solutions can be processed like those of common thermoplastics. The imprinted patterns receive high thermal and mechanical stability through cross-linking polymerization. The course of the polymerization was investigated to determine the appropriate conditions for the imprint process. In thermally cross-linked polymers mr-I 9000, the cross-linking occurs during imprinting. Process time and temperature depend on the polymerization rate. Volume shrinkage during the polymerization does not adversely affect imprinting. Photochemically cross-linked polymers mr-L 6000 make possible imprint temperatures below 100 T and short imprint times. The T-g of the prepolymer determines the imprint temperature. The cross-linking reaction and structural stabilization is performed after imprinting. 50-nm trenches and sub-50-nm dots confirm the successful application of the polymers.

  • The Pristine survey – X. A large population of low-metallicity stars permeates the Galactic disc
  • 2020
  • Ingår i: Monthly notices of the Royal Astronomical Society. - : Oxford University Press (OUP). - 0035-8711 .- 1365-2966 .- 1745-3925 .- 1745-3933. ; 497:1, s. L7-L12

    • The orbits of the least chemically enriched stars open a window on the formation of our Galaxy when it was still in its infancy. The common picture is that these low-metallicity stars are distributed as an isotropic, pressure-supported component since these stars were either accreted from the early building blocks of the assembling Milky Way (MW), or were later brought by the accretion of faint dwarf galaxies. Combining the metallicities and radial velocities from the Pristine and LAMOST surveys and Gaia DR2 parallaxes and proper motions for an unprecedented large and unbiased sample of 1027 very metal poor stars at [Fe/H] ≤ −2.5 dex, we show that this picture is incomplete. We find that 31 per cent of the stars that currently reside spatially in the disc (⁠|Z|≤3kpc⁠) do not venture outside of the disc plane throughout their orbit. Moreover, this sample shows strong statistical evidence (at the 5.0σ level) of asymmetry in their kinematics, favouring prograde motion. The discovery of this population implies that a significant fraction of stars with iron abundances [Fe/H] ≤ −2.5 dex merged into, formed within, or formed concurrently with the MW disc and that the history of the disc was quiet enough to allow them to retain their disc-like orbital properties, challenging theoretical and cosmological models.

  • The Hidden Past of M92 : Detection and Characterization of a Newly Formed 17 degrees Long Stellar Stream Using the Canada-France Imaging Survey
  • 2020
  • Ingår i: Astrophysical Journal. - : American Astronomical Society. - 0004-637X .- 1538-4357. ; 902:2
  • Tidskriftsartikel (refereegranskat)abstract
    • We present an analysis of the structure, kinematics, and orbit of a newly found stellar stream emanating from the globular cluster M92 (NGC 6341). This stream was discovered in an improved matched-filter map of the outer Galaxy, based on a color-color-magnitude diagram, created using photometry from the Canada-France Imaging Survey and the Pan-STARRS 1 3 pi survey. We find the stream to have a length of 17 degrees (2.5 kpc at the distance of M92), a width dispersion of 029(42 pc), and a stellar mass of [3.17 0.89] x 10(4)M(10% of the stellar mass of the current main body of M92). We examine the kinematics of main-sequence, red giant, and blue horizontal branch stars belonging to the stream and that have proper motion measurements from the second data release of Gaia.N-body simulations suggest that the stream was likely formed very recently (during the last similar to 500 Myr) forcing us to question the orbital origin of this ancient, metal-poor globular cluster.
