Abstract: The present invention is directed to a liquid droplet monitoring and measuring apparatus for use with a liquid dispensing system of the type comprising a nozzle having a liquid dispensing tip and means for delivering the dispensed liquid through the nozzle onto a receiving substrate. Further, the invention provides a method of monitoring and measuring the volume of a liquid droplet as it is being dispensed from a liquid dispensing system comprising a nozzle having a dispensing tip. The main use for the invention is in the fields of drug discovery, genomics, medical diagnostics and other life science-related applications. The invention could also be used in other areas for example in the food industry, cosmetic industry or the chemical industry.

Abstract: A structuring device (SD) for processing a surface of a substrate (SB), comprising a substrate chamber (VC) for mounting the substrate (SB) and a reaction chamber (GC) enabling a gas reaction at a given operating pressure. The reaction chamber (GC) has at least one gas inlet (GL) for a reaction gas and at least one injection outlet (JL) leading into the substrate chamber, while the substrate chamber (VC) is provided with a pumping system (PP) for maintaining a vacuum within the substrate chamber at a pressure not above the operating pressure of the gas reaction in the reaction chamber (GC). The injection outlet (JL) is provided with at least one injection pipe ending into an injection opening of given width, the injection pipe having a length not smaller than the width of the injection opening, the injection pipe forming the gas particles originating from the gas reaction into a gas jet streaming out of the injection opening.
