Picotwist is an innovative high-tech company that develops cutting-edge biophysical devices for the biosciences. Our expertise is based on more than ten years of academic research in the field of single molecule studies， a domain that has revealed itself to be extremely powerful for the understanding of biological systems at the molecular level (DNA/protein interactions， quantitative enzymology， etc....). Magnetic traps are powerful and versatile devices designed to manipulate and monitor single molecules (DNA， proteins) or larger systems (chromatin， cells...) in real-time by applying picoNewton forces on micron-sized beads using a magnetic field. Our flagship product is a fully-featured， plug-and-play version of the magnetic trap apparatus for single-molecule manipulation. This benchtop system is remarkably robust， compact and stable and enables routine experimentation on dozens of individual molecules in parallel and in real-time.
