Under adequate conditions, cavity polaritons form a macroscopic coherent quantum state,
known as polariton condensate. Compared to Wannier-Mott excitons in inorganic …

We report on a laser that is fully embedded within a single live cell. By harnessing natural
endocytosis of the cell, we introduce a fluorescent whispering gallery mode (WGM) …

Optogenetics is a paradigm-changing new method to study and manipulate the behavior of
cells with light. Following major advances of the used genetic constructs over the last decade…

Cellular forces are crucial for many biological processes but current methods to image them
have limitations with respect to data analysis, resolution and throughput. Here, we present a …

Microarrays of OLEDs are used to optically control the locomotion of individual cells in real
time. Close contact (<2 μm) between OLEDs and the aqueous cell culture medium is …

Strong coupling between cavity photons and excited states of biologically produced
recombinant fluorescent proteins in fully tunable optical microcavities is demonstrated. Natural …

Transient receptor potential (TRP) channels are non-selective ion channels permeable to
cations including Na + , Ca 2+ and Mg 2+ . They play a unique role as cellular sensors and are …

Electrochemical biosensors allow simple, fast and sensitive analyte detection for various
analytical problems. Especially immunosensors are favourable due to specificity and affinity of …

Background Neurostimulation of the subthalamic nucleus reduces levodopa-related motor
complications in advanced Parkinson's disease. We compared this treatment plus medication …

The results of deep brain stimulation (DBS) of the globus pallidus internus (Gpi) in six patients
with generalized, focal, and segmental dystonia are presented. Pre‐ and postoperative …
