Abstract
The present invention features a freestanding microfluidic pipette with both solution exchange capability and fluid re-circulation, enabling highly localized and contamination- free fluid delivery within a confined volume in the vicinity of the pipette exit. Preferably, the device features direct positioning, so the pipette can be directed at a point or object of interest, such as a biological or artificial cell, a defined surface area or a sensor element within an open volume, using micro- or nanopositioning techniques. One aspect of the invention provides a free-standing pipette. The free-standing pipette includes a microfluidic device comprising one or more channels with exits leading into an open-volume and a positioning device programmed to hold the microfluidic device at an angle from a horizontal axis.
