Cell surgery with ultrashort laser pulses - the nanodissection system by Rowiak
Hanover, February 28th, 2008 – The Rowiak GmbH introduces the CellSurgeon - a new nanodissection system, enabling nanosurgery in living cells. The laser based system is especially designed for contact-free and gentle manipulation of cells and subcellular structures.
Applications include, for example, transfection of cells, deactivation of cell organelles or investigation of cell dynamics.
Main component of the CellSurgeon is a NIR femtosecond laser. The laser beam is coupled into a microscope and tight focussed by high numerical aperture objectives. Inside the laser focus very high intensities occur, inducing nonlinear optical processes and finally leading to ablation. Cuts generated in that way are limited to nanometer dimensions and thus very precise. Adjacent structures stay unharmed. Especially for the manipulation of living cells and cell structures this is of great benefit because the risk of cell damage is very low. However, manipulation processes are not only precise but also reproducible. Another advantage of the CellSurgeon is its adaptability to different microscopes and imaging procedures. Rowiak offers customized solutions for specific applications. Software includes features for analysis, image processing and automated procedures.
The CellSurgeon is a new instrument with the potential to solve different research tasks in the field of life sciences. Detailed information about the CellSurgeon and further Rowiak products is available at the Analytica 2008 in hall A2 at stand number 421.
