Abstract
An apparatus and method for depositing an aerosol that has an ultrafast pneumatic, shutter. The flow of aerosol through the entire deposition flow path is surrounded by at least one sheath gas, thereby greatly increasing reliability. The distance between the aerosol switching chamber and a reverse gas flow chamber input is minimized to reduce switching time. The distance from the switching chamber to the nozzle exit is also minimized to reduce switching time. The gas flows in the system are configured to maintain a substantially constant pressure in the system, and consequently substantially constant flow rates through the deposition nozzle and exhaust nozzle, to minimize on/off switching times. This enables the system to have a switching time of less than 10 ms.
