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 |
