摘要: Described are drug carriers useful in magnetic resonance imaging (MRI)-guided drug release comprising a shell capable of releasing an enclosed biologically active agent as a result of a local stimulus, e.g. energy input, such as heat, wherein the shell encloses a 19F MR contrast agent. Preferably, the carrier also acts as a contrast enhancement agent for MRI based on the principle of Chemical Exchange-dependent Saturation Transfer (CEST). To this end the shell encloses a cavity that comprises a paramagnetic chemical shift reagent, a pool of proton analytes, and the 19F contrast agent, and wherein the shell allows diffusion of the proton analytes.

摘要: The present invention relates to a ferroelectric varactor (400) that comprises a dielectric-layer stack (408) between electrodes (406, 410). The dielectric-layer stack comprises an alternating layer sequence of at least three dielectric layers. At cc least two first dielectric layers of the dielectric-layer stack are made of a non-single-crystalline first dielectric material having a first dielectric constant, at least one second dielectric layer of the dielectric-layer stack is made of a non-single-crystalline second dielectric material with a second dielectric constant that differs from the first dielectric constant. One of the first and second dielectric materials exhibits a weaker ferroelectric hysteresis. The dielectric material with the weaker ferroelectric hysteresis makes up more than 20% of the total volume of the dielectric-layer stack. The ferroelectric varactor of the present invention achieves high relative dielectric permittivities in the dielectric layers, a high breakdown voltage, a large tuning range at low voltages, and low dielectric losses.
