At some point, microvehicles that are small enough to navigate our blood vessels will enable physicians to take biopsies, insert stents and deliver drugs with precision to sites that are difficult to reach, all from inside the body. Scientists around the world are currently researching and developing suitable microvehicles. In most cases, they are powered

BROOKLYN, New York, Wednesday, February 17, 2021 – A team led by researchers at the New York University Tandon School of Engineering have found a new way of enhancing the performance of electrochemical micro-sensors. This discovery could lead to the detection of biomolecules, such as dopamine, at lower concentrations than is possible today. Their findings

Such is the case

“For decades, chemistry has been governed by two ambitions goals,” says Professor Stefan Tautz, head of the Quantum Nanoscience subinstitute at Forschungszentrum Jülich. “One of these is understanding chemical reactions directly from the spatial distribution of electrons in molecules, while the other is tracing electron dynamics over time during a chemical reaction.” Both of these
