Optical trapping of a single protein.
Self-induced back-action optical trapping.
These summaries represent only a part of all the projects that are on-going in the group. For more information on the research areas, please consult the list of publications link.
We are working on optical manipulation and trapping using
nanostructured metals. This is of interest to trap and manipulate
particles <100 nm (such as virus particles for studies in infection).
Optical trapping of a single
protein.
Self-induced back-action optical trapping.
We have recently demonstrated single molecule DERS sensitivity.
We nanostructure metals to provide enhanced performance as biosensors
or in spectroscopy applications. Our group has made many pioneering
contributions to this field, see for example the invited review paper
featured on the cover of Laser and Photonics Reviews.
Above figure shows flow-through nanohole array sensing, which combines nanofluidics and nanoplasmonics to speed up the sensing.
We are developing ways to control the near-field for enhanced
near-field imaging and spectroscopy. See for example these two recent
works:
Above figure shows hyperspectral Raman imaging of carbon nanotubes,
in collaboration with Lawrence Berkeley Labs.
Above figure shows single-aperture extraordinary optical transmission
to enhance the throughput by 2 orders of magnitude, in collaboration with
Niek van Hulst's group at ICFO.
