    摘要: The application is directed to a sensor element for use in a magnetochemical sensor, which comprises a first gel-like material (10), especially a swellable hydrogel such as polyacrylamide, and a magnetic second material (20) in the form of particles, especially magnetite (Fe304) nanoparticles, embedded in the first material along with a receptor for an alalyte, eg glucose. Changes in magnetic field due to interaction with the analyte are detected with GMR element (50). Applications include biosensors, DNA testing devices, and high throughput screening.

    摘要: The present invention is related to a process for providing an assembly of cell microcarriers, comprising the steps of providing planar, two-dimensional objects having two sides (“flakes”), wherein these objects comprise a material which, upon application of an extrinsic stimulus, is transferred from the planar state into a rolled state, providing cells on one side of said flakes (“cell-bearing side”), transferring the flakes from the planar state into a rolled state (“cell wrap”) by application of said extrinsic stimulus, and coupling at least one type of binding agent to the flakes.
