Liebe Studierende der Physik,

hiermit lade ich Sie recht herzlich zum Physikalischen Kolloquium ein:

Bioanalytics using single plasmonic nanostructures

30.06.2014, 16:15, Hoersaal 6

Novel requirements for bioanalytical methods are raised by emerging trends such as personalized medicine or pathogen detection in environment and food. Here, novel tools for diagnostics are needed, to be used outside of dedicated laboratories, with less qualified personnel and at minimal cost. Plasmonic nanostructures that absorb and scatter light at a characteristic part of the spectrum depending on their size, structure, and shape promise to provide sensing capabilities with the potential for ultrasensitive and robust assays at a high degree of parallelization. Upon binding of molecules, the localized surface plasmon resonance (LSPR) of these structures is changed, and can be used as sensor readout. I will present the use of individual nanostructures (such as gold nanoparticles) for the detection and manipulation of biomolecules (e.g. DNA) based on optical approaches. Changes in the LSPR spectrum due to DNA-DNA interactions and binding, the formation of molecular layers, and the manipulation of DNA, such as site-specific melting and cutting based on plasmonic nanostructures will be presented and discussed.

Viele Gruesse,

Peter Reimann
