“Laser-assisted Thermal-expansion Microinjection”
Patent Application Number (2004) 361448

Stereoscope Microinjection Set-Up Using LTM-1000

Heat-induced expansion of liquid in a sealed capillary generates high pressure, which enables injection by capillaries with the tip diameter around 0.1

m (Knoblauch et al., Nature Biotech., 1999).
As the heat source, we chose a laser beam which enabled us to directly heat hydrophobic liquid containing laser absorber through the capillary glass and to precisely control the injection flow.

*Please be aware that LTM-1000 can not be used for Arecaceae family due to the patent license.
