Release date: 2007-08-07
In a significant breakthrough, a collaborative team from the Japan Industrial Technology Research Institute, Nagoya University, and Tohoku University has developed advanced nanotube-based ultra-micropipettes. This innovation marks a major step forward in precision liquid handling at the microscopic level. The new device uses organic nanotubes, which are engineered to have an inner diameter of 50 nanometers and a length of 10 micrometers. These nanotubes can be attached to the tip of a glass micropipette with an internal diameter of 1,800 nanometers, creating an ultra-precise tool for delicate operations.
The technology allows for the precise delivery or extraction of liquids in quantities as small as one trillionth of a milliliter—far beyond the capabilities of traditional pipettes. By applying an electric voltage, the device can control the ejection of liquid with remarkable accuracy. This level of precision is tens of thousands of times greater than that of conventional micropipettes, making it ideal for applications in biology and medicine.
Potential uses include injecting minute amounts of substances into individual cells or extracting specific cellular components without damaging the cell itself. This advancement could revolutionize fields such as drug delivery, gene therapy, and cellular research. With its high accuracy and versatility, this new technology opens up exciting possibilities for future scientific exploration and medical treatments.
