This Unit offers the possibility of generating nanoparticle aerosols from a large variety of liquid suspensions or nanosized powders. Our patented technology allows a reliable aerosol generation from any preformed micro or nanoparticle powder. These aerosols with known and reproducible characteristics can then be used in wide variety of applications.
For determining the particle size and concentration in aerosol phase, several nanoparticle aerosol spectrometers are also available. These allow a real-time determination of the concentration of particulate matter in air streams and environments from sizes down to 5 nm.
Also, the Unit is able to identify nanosize matter from aerosols using a reliable, ultrasensitive identification in diverse matrices, based in introducing trace amounts of labels (eg. rare earth oxides or flurorophores).
The following devices are available through this service:

Conventional batch reactors may suffer from limitations due to the inefficient heat and mass transfer that makes it very difficult to achieve an accurate control on the synthesis conditions. This has a direct effect on key aspects such as reproducibility, selectivity and scalability. In fact, one of the bottlenecks in the development of Nanotechnology lies in the lack of precise synthesis methods capable of a scaled up production.
Continuous flow reactors based on microfluidic principles offer potential solutions to the aforementioned concerns. The exquisite control afforded by microfluidic reactors enables continuous production of nanomaterials with targeted sizes, shapes and composition. Moreover, the combination with microwave reactors can accelerate the stabilization of metastable phase due to the fast and selective heating supplied by this electromagnetic irradiation.
Customer benefits
The customer can benefit from the Unit´s expertise on the design of versatile microfluidic platforms to produce a broad library of nanostructures in a continuous fashion, often with a strong reduction of processing times with respect to the corresponding batch process. The Unit also offers unprecedented flexibility in terms of tuning the reaction atmosphere. Access to microwave reactors to perform fast heating reactions will be another asset to optimize specific synthesis and/or reactions in liquid media.
Target customer
Pharmaceutical companies, material suppliers, research groups pursuing a controlled and potentially scalable production of materials.
