A method of electron microscopy imaging of samples, using an electron microscope (100) having a microscope column (10) and a transfer device (11) with a grid carriage (12), comprises the steps of preparing multiple samples (1) on a single electron microscopy grid (2), including dispensing the samples (1) with a dispenser device (30) on distinct positions on the grid (2), introducing the grid (1) with the transfer device (11) into the microscope column (10), and electron microscopy imaging of the samples (1), wherein the preparing step includes holding the grid (2) on the grid carriage (12) of the transfer device (11) or on a grid holder device (20) provided at the electron microscope (100) and dispensing the samples (1) on the grid (2) while holding it on the grid carriage (12) or on the grid holder device (20). Furthermore, an electron microscope (100) for electron microscopy imaging of samples is described.


A method of depositing at least one substance on a target substrate (1) comprises the step of operating at least one droplet dispenser (21) such that droplets (2) including the at least one substance are deposited on the target substrate (1), wherein the target substrate (1) has a substrate surface including spatially delimited receptacle sections (3) being arranged for accommodating the droplets (2), and the at least one droplet dispenser (21) is controlled in dependency on the locations of the receptacle sections (3) such that the droplets (2) are directed onto the receptacle sections (3). Furthermore, a dispenser device (100) for depositing at least one substance on a target substrate (1) is described.

A method of depositing single particles (1) onto a target (2) comprises the steps of loading a particle suspension (3) to a droplet dispenser (10) having a suspension reservoir (11) and a nozzle section (12), detecting particles in the nozzle section (12), testing a single particle condition of the droplet dispenser (10), wherein it is determined whether an ejection region (13) of the nozzle section (12) includes one single particle (1), and operating the droplet dispenser (10) for dispensing a droplet, wherein the droplet is dispensed onto the target (2), if the single particle condition is fulfilled, or the droplet is dispensed into a collection reservoir (5), if the single particle condition is not fulfilled, wherein the step of testing the single particle condition further includes determining whether a sedimentation region (14) adjacent to the ejection region (13) is free of particles. Furthermore, a dispenser apparatus (100) dispensing single particles onto a target (2) is described.

Monitoring the quality of drinking water is of paramount importance for public health. Water is not a commercial product but a heritage that must be protected, defended and treated as such (Water Framework Directive 2000/60/EC). The threat of waterborne diseases in Europe will predictably increase in the future as the human population increases and as a result of globalization and migration from non-EU countries and of climate change. Development of efficient, sensitive, robust, rapid and inexpensive tests to monitor various aspects of water quality represents an essential milestone within the strategy for control and prevention of diseases caused by waterborne pathogens and by algal toxins. Traditional methods for the detection of waterborne pathogens, based on cultivation, biochemical characterisation and microscopic detection are laborious and time-consuming; molecular biological tools have now greatly enhanced our ability to investigate biodiversity by identifying species and to estimate gene flow and distribution of species in time and space. AQUA aims to design and develop a universal microarray chip for the high-throughput detection in water of known and emerging pathogens (bacteria, viruses, protozoa and cyanobacteria) and to assess the water quality monitoring the presence of select bioindicators (i.e. diatoms). A chip able to detect cyanobacterial toxins will also be developed. These innovative molecular tools should be amenable to automation so that they could be deployed on moorings for routine semi-continuous monitoring of water quality. AQUA also aims to identify cyanophages potentially capable of controlling and mitigating the periodical blooming of toxic cyanobacteria in drinking water reservoirs. Overall, these innovative and cost efficient technologies will reduce energy requirements and improve performance of water treatment, and allow rapid management response to new situations brought about by environmental (including climatic) changes.

The invention relates to a microdispenser (1) for dispensing a liquid sample in a dispensing device, with a sample container (2) for receiving the liquid sample, and with a nozzle (7) for dispensing the sample located in the sample container (2). The microdispenser (1) with the filled sample container (2) can in this case be stored independently of and fluidically separately from the dispensing device, without the sample escaping from the sample container (2) during storage.
