Title: Manganese oxide helices, rings, strands, and films, and methods for their preparation

Abstract

Methods for the preparation of mixed-valence manganese oxide compositions with quaternary ammonium ions are described. The compositions self-assemble into helices, rings, and strands without any imposed concentration gradient. These helices, rings, and strands, as well as films having the same composition, undergo rapid ion exchange to replace the quaternary ammonium ions with various metal ions. And the metal-ion-containing manganese oxide compositions so formed can be heat treated to form semi-conducting materials with high surface areas.

Method of preparing and applying single stranded DNA probes to double stranded target DNAs in situ

Patent Gray, Joe W [Livermore, CA]; Pinkel, Daniel [Walnut Creek, CA]

A method is provided for producing single stranded non-self-complementary nucleic acid probes, and for treating target DNA for use therewith. Probe is constructed by treating DNA with a restriction enzyme and an exonuclease to form template/primers for a DNA polymerase. The digested strand is resynthesized in the presence of labeled nucleoside triphosphate precursor. Labeled single stranded fragments are separated from the resynthesized fragments to form the probe. Target DNA is treated with the same restriction enzyme used to construct the probe, and is treated with an exonuclease before application of the probe. The method significantly increases the efficiency and specificitymore » « less
