    Abstract: The present invention is directed to a method of sequencing a target nucleic acid molecule having a plurality of bases. In its principle, the temporal order of base additions during the polymerization reaction is measured on a molecule of nucleic acid, i.e. the activity of a nucleic acid polymerizing enzyme on the template nucleic acid molecule to be sequenced is followed in real time. The sequence is deduced by identifying which base is being incorporated into the growing complementary strand of the target nucleic acid by the catalytic activity of the nucleic acid polymerizing enzyme at each step in the sequence of base additions. A polymerase on the target nucleic acid molecule complex is provided in a position suitable to move along the target nucleic acid molecule and extend the oligonucleotide primer at an active site. A plurality of labelled types of nucleotide analogs are provided proximate to the active site, with each distinguishable type of nucleotide analog being complementary to a different nucleotide in the target nucleic acid sequence. The growing nucleic acid strand is extended by using the polymerase to add a nucleotide analog to the nucleic acid strand at the active site, where the nucleotide analog being added is complementary to the nucleotide of the target nucleic acid at the active site. The nucleotide analog added to the oligonucleotide primer as a result of the polymerizing step is identified. The steps of providing labelled nucleotide analogs, polymerizing the growing nucleic acid strand, and identifying the added nucleotide analog are repeated so that the nucleic acid strand is further extended and the sequence of the target nucleic acid is determined.

    Abstract: In order to isoelectrically separate particles with a pH-dependent net charge, the particles are exposed in a guiding liquid to electric field forces. The pH value of the guiding liquid is set in such a way that at least one predetermined type of particle is separated from the remaining particles and migrates to a fixing collecting means under the effect of the electric field forces. The collecting means is for example a porous hollow fiber delimited by electrodes which generate the electric field forces and crossed by the guiding liquid together with the sample to be separated. The particles whose isoelectric point matches the pH value of the guiding liquid run unimpeded through the fibers, whereas the remaining particles are pressed against the inner wall of the fiber and are prevented from being carried away with the liquid flow.

    Abstract: Methods, devices, substrates, and systems are disclosed involving arrays of zero-mode waveguides having nanopores extending through the bases that form the bottoms of the zero-mode-waveguides. Electric fields across the nanopores are used to attach single biomolecules such as polymerase enzymes within each zero-mode-waveguide. Electric fields across the nanopores can also be used for the active loading of nucleic acid templates into enzymes attached within the zero mode waveguides.
