SENSOCELL is an optical tweezer add-on instrument for Nikon inverted microscopes. It can be either installed on a pre-existing microscope or offered in an integrated platform including a new Nikon Ti-2 inverted microscope. The optical tweezers platform is composed by:
- An optical manipulation module that allows optical trapping and manipulation of multiple microscopic samples.
- A force sensor module allowing simultaneous & direct measurement of the exerted optical trapping forces.
- A rack mount case with all electronics and a single-frequency laser source (5W, 1064 nm).
SENSOCELL also comes with LightAce, a powerful, flexible and user-friendly control software suite featuring:
- Extensive control over multiple simultaneous traps.
- Force & position real time data analysis for multiple traps.
- Predefined and customizable automated routines for cell mechanobiology applications.
- The possibility of creating your own routines using a simple and flexible macro language.
