Direct laser writing of fluidic 3D microstructures

With the technology of direct laser writing using two-photon polymerization we can realize complex three-dimensional (sub) micron structures in photopolymer resists. The increased writing speed of modern equipment allows wafer-level processing. In this work we aim to design and fabricate novel microfluidic structures that can be written directly into microchannels to integrate fluidic functionality such as filters, mixers, valves, as well as optofluidic elements. more »

 

3D microfluidic chip holders and systems

The adoption of microfluidic devices is often slowed by packaging challenges, especially reliable connections to the macroworld, and limitations of planar chip fabrication technology. We have revolutionized our packaging approach to 3D-printing custom chip holders and we amended our device possibilities with completely printed fluidic systems. more »

 

Phononic-Fluidic Systems 

The combination of so-called phononic crystals with microfluidic systems is a novel approach to develop a platform exploiting physical properties for the (bio)chemical analysis of liquids and mixtures. Taking advantage of additive fabrication we design and build three-dimensional lattices to control acoustic wave propagation. These structures will then be integrated around and within microfluidic cavities and channels.   more »

 

 

Functional additive fabrication of simple sensor systems

The additive fabrication of objects with electrical or magnetic functionality is still a challenge especially for smaller dimensions. We combine different 3D and screen printing techniques to showcase the possibilities of simply printing custom sensor elements and ‘smart’ parts.  more »

 

 

BOOMER 

Bacterial periplasmic Organelles and Outer Membrane Vesicles

 

Boomer is a co-operation between the Institute for Microsensors, -Actuators and -Systems, the Jacobs University Bremen and Ionovation GmbH. The focus of the joint project is the supply of biological preparations for antibiotic research. In this joint project, state-of-the-art processes from nano- and microtechnology are used for the production and characterization of these preparations.   more »

 

 

 

 

REDHISTO

REDHISTO is developing a system for the infrared spectroscopic analysis of tissue samples. Our focus is to simplify the detection of cancer cells by histopathologists as well as opening new research paths for the biomedical scientific community.

REDHISTO is supported by the Federal German Government through funds from the Ministry of Economy and Energy and through the European Social Fund (ESF). REDHISTO is additionally supported by the Bremer Aufbau-Bank through funds of the Senator of Economy and Ports of the state of Bremen and by the European Regional Development Fund (ERDF).

REDHISTO is winner of the CampusIdeen 2016 contest, organized by the Universities of the state of Bremen and the Bremer Aufbau-Bank.

Life Chip

The LifeChip-Project aims at designing a microchip which enables the cultivation of mammalian cells. Cells will be seeded on specific spots , fed nutrition and oxygen and will be detached. Using hydrogels will create porous walls for the transport of nutrition as well as Parylene to manipulate the surface properties.

BSI - Bedside-Immunomonitoring       

Das Projekt Bedside-Immunomonitoring hat die Entwicklung eines patientennahen Diagnosesystems für Infektionskrankeiten zum Ziel.

Die Analyse der wichtigsten Infektionsmarkern im Patientenblut kann so in kürzerer Zeit und mit deutlich weniger Blut als mit herkömmlichen Tests durchgeführt werden.

Biomedical engineering for cancer and brain disease diagnosis and therapy development (EngCaBra) 

 

The ten partners in the project focus on the realisation of novel devices for analysis of cellular and molecular mechanisms related to cancer and brain diseases. The project is coordinated by Prof. Michael Vellekoop. At IMSAS we investigate new methods for the analysis of biopsies and for the detection of cancer cells in lymph fluid.

Verbundprojekt MaUS - An Autonomous Microreactor System for Detection of Mold Contaminations - Mikroreaktorensystem zur autonomen Untersuchung von Schimmelpilzbelastungen

The MaUS project aims at designing an autonomous sensor system for the detection of mold contaminations in archives and in food transport containers. In collaboration with four industrial partners, various mold detection methods based on optical, electrochemical, fluorescence principles etc. will be investigated. One novel way to design such an autonomous system is to automatize the traditional culturing techniques by integrating an air sampling unit.

Wound Monitoring

 In cooperation with IMA GmbH in Wiener Neustadt and the Vienna University of Technology we study several sensors that can be applied for wound monitoring. The sensors are placed in the bandage covering the wound. Sensors for infrared remission, heart rate, arterial oxygenation, surface pH, moisture, and temperature are investigated and tested. 

Ultimate aim is to improve the healing process of chronic wounds.
