Latest Patents

One of his latest patents involves the development of silica magnetic particles with a high nucleic acid binding capacity. This invention focuses on magnetic particles for nucleic acid isolation that are coated with silica. The particles are separated from impurities and nanoparticulates using a multi-step fractionation process. In each cycle of this process, the particles are stirred, sedimented, and resuspended, leading to a decline in pH. By repeating the fractionation process until the resuspended particles reach a target pH of about 9 to 10.5, and their zeta potential becomes more negative than about -40 mV, a purified population of particles is achieved. This results in a high and reproducible binding capacity for nucleic acids. The silica-treated magnetic beads produced by this method offer improved sensitivity and consistency for the recovery of nucleic acids in a sample.

Another notable patent relates to oligonucleotide sequences for amplification primers and detection probes. This invention is aimed at enhancing nucleic acid amplification methods for the selective and specific detection of biological samples. It provides oligonucleotide primer sets and primer/probe sets in the form of kits for the detection and diagnosis of gonococcal infection. The inventive oligonucleotide primers and probes can also be used in combination with other specific oligonucleotide primers and probes for the simultaneous detection of other target organisms.
