摘要:
The present invention provides for the coaxial encapsulation of a plurality of cells in a single elongated compartment. By this encapsulation, the cells are protected by at least one layer of separation material and kept in close contact, which leads to a better vitality of the encapsulated cells and consequently results in higher chances to form microtissue. Methods and devices for the production of such encapsulated cell compartments are disclosed as well as medical uses of such compartments in cell, tissue therapy and tissue engineering.
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.

The present invention relates to a bio chip for fractionating and detecting analytes, such as proteins, protein-complexes, metabolites, glycoproteins, peptides, DNA, RNA, lipids, fatty acids, carbohydrates and/or other ampholytes.
摘要:
The present invention relates to a method for the production of scaffold materials and/or scaffolds for tissue and/or organ engineering, said method comprising the addition of at least one anchoring unit for a labelling agent, to at least one scaffold material and/or to at least one scaffold.
摘要:
A micro system power supply (1) comprises a compartment (7), at least one ion sink void (51, 52) being separated from the compartment (7) by ion pervious separation means (61, 62), a first electrode (41) being arranged in the ion sink void, and a second electrode (42). Such a micro system power supply (1) allows to provide power for a micro system, such as, e.g., an implantable micro device, a MEMS, a bioMEMS, or the like, wherein the micro system power supply (1) can be comparably efficiently manufactured in a manner to be comparably environmentally friendly disposable.
摘要:
The present invention is related to scaffolds for tissue engineering and organ engineering. More particularly, the present invention is related to a method for the production of a labelled scaffold for tissue and/or organ engineering comprising a reactive fluorinated surfactant, which serve as imaging label for medical imaging means, like CT, MRI, PET, scintigraphy and/or ultrasound imaging and the like.
摘要:
The invention relates to a nuclear magnetic resonance imaging radio frequency—receiver (112; 216; 308; 404), the receiver (112; 216; 308; 404) being adapted to receive analogue signals from at least one radio frequency receiver coil unit (106; 200; 202; 300; 400; 402), the radio frequency receiver (112; 216; 308; 404) comprising: an analogue-digital converter (118; 226) to convert the analogue pre-amplified magnetic resonance signal into a digital signal, means (120; 230) for digital down converting the digital signal and a first communication interface (130; 252) adapted for transmitting the down converted digital signal via a communication link (e.g. wireless, optical or wire-bound).
摘要:
The invention relates to a valve for opening and closing a channel (3) of a microfluidic system, respectively. According to the invention, the valve comprises an actuation medium (2) that undergoes a volume change with changing temperature; and a heater arrangement (5) for generating a temperature gradient in the actuation medium (2) with respect to the actuation medium's (2) distance relative to the channel (3); wherein due to an expansion or a contraction of the actuation medium (2) the channel (3) is closed or opened, respectively. When the heater arrangement (5) is activated in such a way that a higher temperature is generated in the actuation medium (2) which is nearer to the channel (3) and a lower temperature is generated in the actuation medium (2) which is further away from the channel (3) the valve can be closed and vice versa. Accordingly, such a valve for a microfluidic system is provided which can be reliably actuated during a long time of use.

The invention relates to a substrate material for analyzing fluids which has first areas with a high porosity and second areas with a lower porosity.
摘要:
The present invention is related to a method for the production of cell sheets comprising at least two different cell types, said method comprising the steps of providing a continuous cell sheet which is disposed on a substrate comprising shape transition properties and/or alterable surface characteristics; exposing said continuous cell sheet to a releasing agent in a patterned fashion; washing the cell sheet after exposure to the releasing agent in order to remove cells which have been affected by the releasing agent, and repopulating the gaps remaining after the cells which have been affected by the releasing agent have been removed with a second cell type.
