This is how the IR spectrometer works: The photodetector, fabricated on top of a surface optical waveguide, consists of a bottom gold electrode at the bottom functioning as a scattering center, a photoactive layer (consisting of colloidal mercury telluride – HgTe – quantum dots), and a top gold electrode. By moving the mirror, the measured photocurrent maps the light intensity of the standing wave. i.e. the IR light. A Fourier transformation of the measured signal gives the optical spectra.

A breakthrough: Tiny circulating microrobots, which are as small as red blood cells (left picture), were visualised one-?by-one in the blood vessels of mice with optoacoustic imaging (right picture). (Image: ETH Zurich / Max Planck Institute for Intelligent Systems)

New imaging recognizes cell-sized microrobots individually and at high resolution in a living organism
