20 Clean laboratory produces tiny laser


hile many researchers are fortunate to be able to use on-site cleanroom facilities, what if these are unavailable? Many scientists and engineers are faced with the problem of either going to the great expense of building a cleanroom, which may be impractical for start-up companies, or the inconvenience of

travelling long distances to rent, beg, borrow or steal facilities from others. An example of a researcher using external cleanroom facilities to develop a miniature laser is described on page 20. But a more common scenario is that of Dr Gianmario Scotti from the

array Finnish researchers have been using clean nanofabrication facilities to produce an operating dark lattice plasmonic nanolaser.

University of Helsinki, Finland. He was fed up working in the cleanroom about 15 km away from his lab. The microchips intended for mass spectrometry analysis had to be prepared in bigger batches, as there was no point spending time suiting up and using the cleanroom for just a single device at a time. That of course meant waiting for the batch to be ready before it could be used by the research group, and the work was not proceeding as fast as he would wish. Then Scotti and a colleague had an idea. Maybe they could skip the cleanroom phase by devising a small, disposable container which could be directly connected to a mass spectrometer and used to study reactions? With the help of some lateral thinking, a few grammes of plastic filament and a 3D printer, they made an unique device for studying chemical reactions, and improved their experimental processes. 3D printers are not hard to find, and printing one microreactor at a time takes about an hour. Finding the right material, however, was not an easy task. The material had to be such that the solvents used in chemical reaction studies would not dissolve anything from it. It also had to be durable and easily printable. Polypropylene filament seemed an interesting option. After a handful of developmental phases the researchers created a microreactor that can be used for mass spectrometry analysis. An additional challenge was to find a suitable platform on top of which the microreactor could be printed. The printed plastic needs to stick to the platform, but not too strongly. The researchers found that polypropylene itself is also the best platform material, but the temperature of the printed plastic must be carefully regulated. The term “microreactor” sounds complicated, but basically it is just a small container with a stir bar for mixing chemical samples and a very thin needle for spraying and ionising the sample for analysis with a mass spectrometer. The microreactor itself sits in a plastic jig to which the sample syringes are connected. The jig itself is – of course – also 3D printed. A miniature cleanroom for work on a molecular scale!
