Highly functional: microfluidic biochips for the biotechnology of the future

IMT is one of the pioneers in the area of microfluidic glass components and biochips. As early as 1990, our technology allowed for the development of the first µTAS chip by Andreas Manz.
The combination of automated semiconductor processes with existing MEMS technology opens up brand-new possibilities for our customers.
There are even new fields of application in cost-sensitive areas, in which it has not previously been possible to consider optical glass.

Droplet-generating chips for precise dosing of very small volumes

Customer-specific droplet generators from IMT are used for the precise dosing of very small volumes. Our elements are characterised by an extremely wide range of shapes, channel depths and surface properties.

The production technology allows for a channel surface roughness of <20 nm and therefore elements with excellent optical and microfluidic properties.

Impedance flow cells for cell analysis

Consisting of a combination of channels and electrodes, flow cells are used in impedance spectroscopy. By creating an alternating voltage, the alternating current resistance (impedance) is measured as a function of the frequency, which makes it possible to determine various parameters, such as cell size.

The production of the chip takes place on two separately processed wafers (substrates). On the first wafer, modern semiconductor technology is used to produce channels and electrodes, which are then hermetically sealed with the second wafer using room temperature bonding.

IMT also produces customer-specific systems with two electrodes. In order to do this, we insert a structurable intermediate coating between the wafers after structuring the electrodes.

Glass chips for electrophoresis

Electrophoresis refers, generally speaking, to the movement of charged particles or molecules through an electric field. The speed of the particles is essentially determined by their shape and size. In biochemistry and molecular biology, this relationship is used to separate short and long molecule strands.

New lithography processes allow us to combine glass channels with easily accessible gold structures.
