New publication using Attana Technology demonstrates that maize and milk proteins can replace fossil fuels and metals in the production of high-tech functional surfaces
Nanotechnology can be found almost everywhere in our daily lives, although it is nearly impossible to see. Nanostructures are materials that have been processed at the atomic level to obtain desired material properties. They are used, for instance, in electronics, diagnostics, and as surface treatments for textiles.
Prof Nicholls and Dr. Suriyanarayanan at the Linnaeus University has in a recent publication demonstrated how high-tech nanostructures can be made from food components such as proteins from milk and maize.
Nanostructural materials can significantly improve the performance in financial important areas such as electronics, diagnostics, and as surface treatments for textiles. However, the fabrication of these materials often requires the use of materials with limited natural resources. Nicholls and Suriyanarayanan have used, amongst other proteins from milk and maize to produce highly regular nano-structural hyperporous networks or nano-wire like surfaces. Fully implemented this means significant improvements for a sustainability perspective.
To produce the nanostructure surfaces, protein from maize, milk, and crab-shell were functionalized on e.g Attana sensor chips. The functionalized surfaces were characterized by SEM (surface morphology), QCM (mass), IR spectra (chemical composition), profilometry (thickness) and Impedance spectroscopy (Permeability).
Attana Cell 200 and Attana A100 instruments were used to evaluate the surface performance. A series of biotin imprinted nanostructures were compared with their non-imprinted counterparts and non-nanostructured coatings. The selective binding to biotin was demonstrated and the surfaces showed significant enhancements is sensitivity. The study also demonstrates the sensitive and linearity of the Attana technology which is for instance the properties that enables Attana to perform the world leading interactions studies between analytes and cell surfaces.
In conclusion
Many nanostructures are currently produced from different types of metals and derivatives from fossil fuels. This research demonstrates the potential to replace fossil fuels and metals in nanotechnology in the future with sustainable, renewable and readily available raw materials.
