Molecular Biosensing

The MBx group develops technologies based on micro- and nanoparticles for monitoring patients and for treating diseases. Towards this goal, the unique approach of MBx is to use advanced optical imaging techniques that quantify molecular processes with single molecule resolution within complex biomacromolecular environments.

Quantify molecular processes with single molecule resolution

The MBx group creates concepts in the field of molecular biosensing with diagnostic and therapeutic healthcare perspectives. Combining nanotechnology, molecular engineering and single molecule imaging technologies we aim to measure with ultimate sensitivity biomolecules implicated in a variety of diseases, such as cancer, immunology, and cardiology.

Video on Plasmonic Biosensing using Metal Nanoparticles

Metal nanoparticles provide the possibility to detect single molecules without the need for labeling, enabling the direct detection of non-absorbing species [1]. A molecule that binds to receptors on the surface of a particle induces a change in the local refractive index that in turn results in a change of color due to a shift of the plasmon resonance [2,3]. This animation illustrates the real-time detection of plasmon shifts induced by molecules binding to functionalized single gold nanorods. The plasmon shifts are measured by monitoring scattering intensities of many particles simultaneously and in real-time [4].
