Current Research

Single cell analysis is an active research domain, which allows highly local investigation and manipulation of the inner body parts of the living cells. The efficient delivery of molecules into living cells without compromising cell viability holds promising value for therapeutics. The goal of this project is to address the need of tools for single cell analysis, providing a biocompatible nano needle with various actuation and sensing capabilities. 
The goal of this project is the development of miniaturized magnetoelectric energy harvesters. Magnetoelectric (ME) materials become magnetized when placed in an electric field and electrically polarized when placed in a magnetic field. ​This effect can be utilized for new concepts in the field of energy harvesting.​​
In this project, magnetic nanowires are investigated for transformational disease therapy, i.e. cancer treatment. Iron nanowires are characterized by a single domain behavior. As a consequence, they have very high remanence and coercivity values. These properties can be exploited for generating heat in a high-frequency magnetic field, or oscillations in a low-frequency magnetic field. When in contact with cells, the heat or oscillations induce their apoptosis.
Delivery devices that allow remote, repeatable, and reliable switching of drug flux are expected to greatly improve the efficiency of treatment of a variety of medical conditions and to have a large impact on the biotechnology market. This project aims for the develop of an implantable device, which is operated by a passive osmotic pump and controlled by a magnetically triggered membrane.​​
​The employment of micro/nano size superparamagnetic beads as biomolecular tags/labels has recently attracted significant interest as an alternative to commonly used methods such as fluorescent dyes or enzymes due to various advantages. The goal of this research project is to develop, in a first step, on-chip magnetic micro and nanoparticle manipulators to enable motion control for separation or concentration and, in a second step, integrate the manipulators with magnetic micro sensors to quantify the particles .​​
For many years, nature has been a source of inspiration for engineers and a myriad of structures and materials have been mimicked to achieve outstanding sensing performance with extreme reliability and robustness. One structure commonly found in nature is the “cilia”. Cilia are micro-scale, hair-like structures that exist in many forms (e.g. mechano-sensory hairs of crickets or fish). When cilia are bent, they transmit a signal to the organism, which is translated into a specific function.    ​​
​Magnetic field sensors represent one of the most pervasive types of sensors today in e.g. automotive applications and process control, and they are becoming increasingly important in other fields like biomedical applications and communication electronics. In many applications, a sensor would be preferred or required that is operated wirelessly and passively.​ ​
The laser induced graphene (LIG) sensors with outstanding mechanical, electrical and thermal properties are introduced for marine applications: to measure key ocean properties and monitor the speed of free-living marine animals  ​
The goal of this project is to develop a battery-less acoustic tag for aquatic animal tracking.    ​
