Particle-based systems

Nanoparticles with a diameter in the range of 50 up to 300 nanometers are synthesized at Fraunhofer IGB of organic as well as inorganic materials. Our research focuses on the design of customized nanoparticles as carriers for biotechnology and medicine and separation tasks in chemistry and environmental applications.

Furthermore we have established inkjet printing technologies, to generate two- or even three-dimensional structures. At Fraunhofer IGB ink formulations for processing a variety of functional components such as hydrogels, nanoparticles, proteins and conductive materials are developed.

Fields of research

 

Core-shell particles for chemistry and environment

Core-shell particles are functional composite materials combining at least two different functions: those of the particle core and those of the particle surface or shell. We focus on the design of the surface, e.g. by binding biological molecules, and on additional functions of the core, e.g. by loading with dyes or magnetic properties.

 

Active agent formulation

A major challenge in medicine is the selective transport of active agents to the damaged tissue or organ. Cell membranes are the most important barriers for a targeted drug delivery. Another problem is the degradation or derivatization in the body. A way to circumvent these disadvantages is the manufacturing of particulate active ingredient formulations, where the active agent is bound into a polymeric shell or matrix.

 

Printing processes and formulation of inks

Among the established printing techniques, inkjet printing offers a highly attractive technique to generate two- or even three-dimensional structures that have been designed before at the computer. At the Fraunhofer IGB ink formulations for processing a variety of functional components such as hydrogels, nanoparticles, proteins and conductive materials are developed.
