Research Focus

Project objectives of the Research Unit ‘Nanoparticles’ are advanced method development and its implementation for the fabrication of novel nanomaterials, and the application of these nanomaterials in biomedical science and regenerative nanomedicine, as well as its translation into clinical use.
Applying the techniques of pulsed laser ablation in liquids (PLAL) and in-situ bioconjugation, the RU works on the fabrication of ultrapure mono- and multimaterial nanoparticles in different research directions:

  • Innovative nanodrugs for the directed, cell-selective transport of therapeutics and for controlled ion-, drug-, and gene-delivery purposes.
  • Non-bleaching nanomarker for advanced and specific immunolabeling and high-resolution, real-time bio-imaging.
  • A new class of nanomagnets for efficient recycling of bioactive substances and for controlled cell manipulation and stimulation.
  • Multiparametric nanosensors for the highly sensitive and precise detection and online monitoring of analytes in complex media.
  • Biocompatible nanocomposites for the creation of novel implants with decreased infection rates and self-healing ability for reconstructive therapy.
  • Highly efficient nanocatalysts for the regulation of biocatalytic reactions.
  • The implementation of multifunctional nanomaterials with combined targeting, imaging and therapeutic function as theranostic agents.
  • Risk assessment of nanomaterials and evaluation of biocompatibility and potential cytotoxicity for their approved medical and clinical application.
