| 20090017306 | HYDROPHILIC HARD COAT FILMS - The invention concerns a composition containing a) colloidal silica; b) an acrylate; c) a protic solvent; d) a photoinitiator; and e) an anionic sulfur-containing surfactant, the use of the composition for coating substrates, and substrates coated with such formulations. | 01-15-2009 |
| 20090104395 | Disc-shaped high-density recording mediums - Optical recording mediums comprising a substrate and a recording layer and a light transmitting layer sequentially disposed on the substrate; wherein the substrate comprises one or more parts selected from the group consisting of injection molded parts, injection molded sandwich structures having a molded surface layer and a molded core layer or two injection molded parts which are UV-bonded, and combinations thereof; and wherein the substrate has a Young's modulus E of at least 2.15 GPa and a Q factor of lower than 160 measured at 25° C. at 2000 Hz in accordance to ASTM E 756-05. | 04-23-2009 |
| 20090171052 | Polyelectrolyte Monolayers and Multilayers for Optical Signal Transducers - Polyelectrolyte monolayers and multilayers for coating optical signal transducers are disclosed. | 07-02-2009 |
| 20090252884 | SILICA-CONTAINING UV-CROSSLINKABLE HARDCOAT COATINGS COMPRISING URETHANE ACRYLATES - The present invention relates to a UV-crosslinkable composition comprising a) unmodified, protonated silica nanoparticles; b) urethane acrylate; c) polar solvent; and d) UV initiator system, wherein the amount by weight of unmodified, protonated silica nanoparticles exceeds the content of urethane acrylate and is at least 50.1 wt. %, based on the dry weight of the coating, to the use of the composition in the coating of substrates, and to substrates coated with such formulations. | 10-08-2009 |
| 20100009375 | Silica Magnetic Particles with a High Nucleic Acid Binding Capacity - Magnetic particles for nucleic acid isolation are coated with silica and separated from impurities and nanoparticulates using a multi-step fractionation process. In each cycle of the fractionation process, the particles are stirred, sedimented, and resuspended, resulting in a decline in pH of the suspended particles. Repeating the fractionation process until the resuspended particles have dropped to a target pH in the range of about 9 to 10.5, and their zeta potential is more negative than about −40 mV, results in a purified population of particles with a high and reproducible binding capacity for nucleic acids. The silica-treated magnetic beads produced by the method offer improved sensitivity and consistency for recovery of nucleic acids in a sample. | 01-14-2010 |
| 20100086488 | HYDROPHILIC NANOPARTICLES WITH FUNCTIONAL SURFACE GROUPS, PRODUCTION AND USE THEREOF - The present invention relates to nanoparticles having a hydrophilic surface coating, to methods of production thereof and to the use thereof in biological, molecular biological, biochemical and medical applications. | 04-08-2010 |
| 20100279429 | Method and Apparatus for Increasing the Sensitivity of a Biosensor Used in a Planar Waveguide - Systems, methods and apparatus are provided for mixing an analyte in a planar waveguide cartridge. The invention includes adding magnetic particles to an analyte containing one or more types of target molecules; inserting the analyte and magnetic particles into the cartridge; and moving a magnetic filed proximate to and around the cartridge containing the analyte and magnetic particles, wherein the movement of the magnet field causes movement in the analyte. | 11-04-2010 |
| 20100285321 | HYDROPHILIC HARDCOAT COATINGS - The invention relates to a composition comprising a) colloidal silica; b) acrylate; c) protic solvent; d) UV initiator system; and e) singly charged anionic, sulfur-containing surfactant, to the use of the composition to coat substrates, and to substrates coated with formulas of this kind. | 11-11-2010 |
