The unrivalled thinness of our CNMs has significant advantages against traditional products when being used as support film for TEM grids. In transmission electron microscopy, the electron beam has to pass not only through the sample but also through the underlying carrier layer. The thicker this layer is in comparison to the dimensions of the sample, the poorer the quality of the TEM signal gets and the sharpness of the "picture" gets lost.
To examine samples in the scale of below 10 nm, TEM grids covered with our ultrathin CNM (thickness of 1-3 nm) show significantly better results.
We are currently working on solutions for applications in the area of clean energy technology and environmental technology. The main focus is in the energy-efficient filtration and cleaning of gas stream (e.g. the sequestration of CO2 from flue gases, recovery of process gases like hydrogenand helium in production processes or the detection of leakages in vacuum technology). A further development of the basic technology will be in the future the ultrafiltration of liquids (e.g. water, waste water or process liquids). Our products can be also used as coatings of electrodes or other components in fuel cell technology.
In the area of electronics, we are working on the integration of our nanomembranes in pellicles (protective films used in semiconductor manufacturing). One problem for the current development of extreme-ultraviolet lithography (EUVL) is the poor transparency of current pellicles for the extreme ultraviolet radiation. High losses in productivity for the chip manufacturers are the consequence. Due to the reduced thickness and the composition of our membranes, we are offering an innovative solution with the potential of huge improvement.
The possibility of functionalisation is important for many uses in medical and biotechnology. We are developing within a project funded by the European Commission (www.poc-id.eu) a membrane which is functionalised on one side by biomolecules and which will be used as a detector for pathogens and host responses for the rapid diagnosis of infectious respiratory diseases. A practitioner can thus analyse a patient’s blood or saliva sample in a rapid and easy way without having to wait for the answer from a central laboratory.
Another possible application in medicine is the separation of air into oxygen and nitrogen in a small mobile unit for the oxygen support of patients with a lung dysfunction. The less energy is needed for suctioning in the air and pressuring it through a separation membrane, the longer is the operating time of the mobile unit with one battery charge thus giving the patient a higheer degree of mobility and more freedom in his daily life. The minimal thickness of our membrane offers the high potential of improvement in this application compared to current used technologies for air separation.
There is a huge variety of applications possible in nanotechnology. The increasing demands on minimising the space for components e. g. in mobile phones leads to a continuous shrinking. A microphone can be only made smaller when the membrane is reduced in size. However, the characteristic can be only maintained if the membrane thickness is reduced correspondingly to its diameter. The unrivalled thinness of 1 to 5 nm of our membranes is here of importance.
