Optical Tweezers for Mechanobiology

Impetux is a worldwide key supplier of turnkey optical tweezers systems designed for mechanobiology studies in living cells and 3D tissues.

Mechanobiology is a growing topic that is bound to have a great impact on diverse research fields like cancer, morphogenesis, immunology or regenerative medicine. The optical tweezers platform SENSOCELL™ enables outstanding and unprecedented optical trapping experiences for those researchers exploring new ways to boost their research:

  • Perform multiple optical trapping experiments with simultaneous force measurements and active/passive micro-rheology tests inside living cells or 3D tissues.
  • Manipulate individual cells or cell organelles like nuclei, membranes or other native structures while tracking the forces involved in a non-invasive way.

Our worldwide patented technology not only allows measuring rheological properties and forces where others cannot but also gives unprecedented ease of use of optical tweezers for cell mechanics studies. Check the unique capabilities of our optical manipulation module Cygnium ™ G-422 and force sensor Lunam ™ T-40i to know more.
