Abstract: Magnetische Nanopartikel werden durch eine dünne Membran hindurch erkannt, die die Nanopartikel von einem Magnetsensor trennt. Die Technik kann in einem medizinischen Kontext verwendet werden, in dem ein Analyt von Interesse (vorhanden in einem Prüffluid, wie beispielsweise Blut) an die Membran angelagert ist. Andere Verbindungen sind wiederum an den Analyten gebunden, wobei eine dieser Verbindungen ein magnetisches Nanopartikel enthält, das dann von dem Sensor erkannt wird. Auf diese Weise wird der Analyt durch Erkennung des magnetischen Nanopartikels erkannt. Durch Zählen der Anzahl von magnetischen Nanopartikeln kann die Konzentration des Analyten in dem Prüffluid ermittelt werden.

Abstract: Provided are inorganic-organic block copolymers that self assemble without the addition of a precursor. The inorganic block of the polymers includes silicon and the organic block may be any organic polymer. The inorganic-organic block copolymers self assemble to form a material in which the inorganic polymer block may be crosslinked to produce an organosilicate and/or silica matrix, and further thermal curing of the matrix results in the formation of a porous nanostructured film.

Abstract: Magnetic nanoparticles are detected across a thin membrane that separates the nanoparticles from a magnetic sensor. The technique can be used in a medical context, in which an analyte of interest (present in a test filud, such as blood) is attached to the membrane. Other compounds are in turn bound to the analyte, with one of these compounds including a magnetic nanoparticle that is then detected by the sensor. In this way, the analyte is detected by detecting the magnetic nanoparticle. By counting the number of magnetic nanoparticles, the concentration of the analyte in the test fluid can be determined.
