Definitions

  • the invention relates to a method of arraying nanoparticles and macromolecules on surfaces in order to obtain an arrayed immobilisation of said particles in a desired pattern.
  • the object of the present invention is to provide a method of arraying nanoparticles and macromolecules on surfaces.
  • a pattern of surface defects are created on a surface, the form, appearance and mapping out of the surface defects being adapted to those nanoparticles and/or macromolecules which are to be arrayed.
  • holes and/or rises having a diameter and a depth and a height, respectively, within the interval of 1 - 50 nanometers, and a mutual distance within the interval of 0.1 - 1000 nanometers are created.
  • surface defects in the form of lines are created in the surface.
  • a surface comprising organic or inorganic material.
  • the surface is coated with polymers of inorganic or organic material before the creation of surface defects, and subsequently selective surface modifications are made in order to provide the area containing the surface defects with desired chemical or mechanical characteristics.
  • the thickness of the coating is varied throughout the surface whereby holes with different depths and/or diameters can be created.
  • the surface defects are created by using finely focused ion beam technique
  • the source of ions is indium, gallium, platinum, gold, silver or copper.
  • the surface defects are created by nanoindenting with a diamond- pointed probe used in scanning probe microscopy. Short description of the drawings
  • Fig. 1A and B show arrays of surface defects created by a finely focused ion beam before and after exposure to a solution of human serum albumin
  • Fig. 2A and B show arrays of surface defects created by nanoindenting .
  • a variation of the diameter of the holes makes it possible to vary the number of molecules or paticles being adhered to these.
  • the holes or rises are made with molecular dimensions, which means that single molecules or particles can be adhered to the underlayer.
  • the ion source can be variated so that a material which is most suitable for the intended application can be deposited on the defect made in the surface, to which material a stronger immobilisation of a macromolecule or particle can be made.
  • Protein molecules are strongly adsorbed to platinum and palladium, and in this case the ion source for the finely focused ion beam should be platinum or palladium.
  • Another method would be sputtering of gold onto the surface defects, to which tiolated proteins or particles are immobilized.
  • Defects are created in the surface with the aid of f inely focused ion beam technique or nanoindenting technique .
  • E . g . lines with a suitable depth and diameter are made in the surface.
  • Nanoparticle of organic or inorganic origin are added to the surface and they will collect in the created defects.
  • Excess nanoparticles are removed mechanically with pressurized air, shaking, centrifugation or any other suitable method for removal . Thereafter the surface provided with particles is heated to melting point in order to obtain a continuous thread of the material, intended for different uses such as information transfer.
  • nanoparticles or macromolecules fitting in the holes can be added.
  • the nanoparticles may e.g. consist of the well known bioactive substance hydroxyapatit or other types of bioactive materials to which the cellular surface adheres.
  • suitable macromolecules are the so called integrin family, i.e. vitronektin and fibronektin, which are so called cellular "glues" for adhering of cells to different surfaces.
  • Biomolecular memories Since the surface can be modulated in x- , y- , and z- directions there arises the possibility to create a surface above this topographical chart, which surface varies in x- , y- and z-directions physically-chemically by adding e.g. peptides or amino acids to positions on the surface having been ion beam treated or nanoindented.
  • voltage differentials can arise, which can be used as signal generators.
  • Other possibilities are the use of the artificially created memory surface for separation or analysis.
  • the memory surface can be used for the development of drugs, where a certain membrane structure corresponds with a pharmaceutically active molecule structure .
  • Analytical measuring methods and separation methods for analysis and separation of single molecules and particles can be coated with polymers of inorganic or organic material. With the ion beam can then selective surface modifications be done, which result in that the ion beam treated area will have other chemical or mechanical characteristics. To these areas a selective particle or molecule binding-in can be obtained. Since the applied surface coating can be made with varying thickness there is also the possibility of making holes with different depths but also different diameters, e.g. for molecular filter applications .
  • Biocatalytical systems most often exists bound to sur- faces.
  • the catalyse is achieved among other things because of reduced diffusion distances and because high local concentrations can arise.
  • Other examples of important factors for increased biocatalyse exist in photosynthetic systems where voltage differences are used for electron cascades.
  • a positioning of molecules means that these characteristics can be used to a full extent, which can be performed with finely focused ion beam technique, but also with nanoindenting.
  • a well ordered array of defects was prepared on a silicon surface, using a finely focused ion beam with 30 keV indium ions m a 11 pA beam current.
  • the beam spot size was 15 nm, and approximately a 10 second milling time was used for each 5 ⁇ m x 5 m area.
  • the total array consisted of 16 milling areas, each with an array of holes with an estimated diameter of 50 nm.
  • the spacing between individual defects was about 160 nm.
  • the defect array was imaged with a scanning force micro- scope run m tapping mode (TM-3FM) under ambient conditions.
  • the scanning force microscope employed was a Nanoscope III 115 (Digital Instruments Inc., Santa Barbara, CA, USA).
  • Human serum albumin (HSA) (Sigma Chemical Co., St Louis,
  • HEPES buffer N- [2-Hydroxy- ethyl] piperazme-N' - [2-ethanesulfon ⁇ c acid]
  • pH 7.5 pH 7.5
  • 30 ⁇ l of the HSA solution was placed on the silicon so that it covered the array, and was then rinsed off with 1 ml of HEPES buffer after 2 minutes. The surface was then dried using a flow of nitrogen, and probed again with TM-SFM.
  • the holes have only very slightly elevated rims (Figure, 1A) .
  • the depth of the holes may not de detected with the AFM, due to the bulkiness of the tip compared to the size of the hole .
  • the rims of the holes were decorated with several molecules of HSA (Figure, IB) . There were very few or none of the HSA molecules adsorbed on the areas between the defects ordered in arrays. There was clearly a selective adsorption of HSA molecules to the well ordered array of defects.
  • the image size in Figs 1A and IB, respectively is l ⁇ m x l ⁇ m.
