Vertical voyage in metal halide perovskites

We have developed an approach based on ultrafast near-field microscopy that has allowed us to probe the nanoscale topography, crystallographic phase and chemical composition of metal halide perovskite films, while simultaneously extracting the ultrafast vertical carrier dynamics from femtosecond shifts in the pump-induced response following photoexcitation.

Atomic-scale telegraphy with light

We have discovered an entirely unforeseen quantum-mechanical contrast mechanism that finally enables all-optical microscopy to achieve atomic resolution while retaining subcycle temporal precision. This new concept allows us to directly trace the quantum flow of electrons on their intrinsic length and time scales.

Tracing the wonders of oxygen

Novel microscope traces the first steps of achemical reaction by measuring the interaction of oxygen with a single molecule with unprecedented resolution.

Unravelling the conformational heterogeneity of human Argonaute2

To gain an in-depth understanding of the mechanistic complexity and dynamics of hAgo2 researchers at the RUN performed time-resolved single-molecule FRET measurements – a method that allows distance measurements in the subnanometer range. Combining biochemical and biophysical expertise in one lab ultimately allowed the team led by Prof. Dina Grohmann and Dr. Sarah Willkomm to monitor conformational changes of hAgo2 in real-time with millisecond time resolution.

A lightning-fast atomic hand

Researchers at the RUN have found a fascinating way to push a select atom with controlled forces so quickly that we can choreograph the motion of a single molecule within less than a trillionth of a second.

Unleashing the prowess of picosecond time-resolved photon antibunching

Researchers unveil the unprecedented capability to precisely gauge the authentic count of chromophores and track exciton diffusion in DNA origami and conjugated polymer aggregates at mind-boggling ultrafast time scales.
