In medicine and biotechnology, laser technology makes a multitude of analytical, diagnostic and therapeutic applications possible. Since laser-based optical measuring and processing processes do not touch the objects they measure, they are ideal tools, in particular when used under sterile and highly selective conditions. They are suitable both for the production of appropriate instruments for medical technology as well as for diagnosis itself.
Fraunhofer ILT develops microfluidic structures and systems for customized applications. With laser-based processes, materials can be characterized, selectively modified on the surfaces or precisely machined on the inside. Not only can plastic, ceramics or silicon be processed, but also glass, metals or hybrid material combinations. For example, the institute uses and continues to develop Selective Laser-Induced Etching (SLE) to produce precise microchannels, holes and cuts in, for example, transparent components made out of chemically resistant materials such as fused silica, borosilicate glass, sapphire and ruby. Among other things, microfluidic systems with such channels are used in lab-on-a-chip solutions, which enable fast multiplex diagnostics. The micrometer-fine structures can be produced directly from 3D CAD data. In addition, the systems can be sealed by laser radiation with little mechanical or thermal influence.
The services offered encompass component development, the rapid production of prototypes for design validation, the development and implementation of assembly and connection techniques, technical function tests and developments for quality control as well as individual consulting.
