In a groundbreaking study published in Nano Letters, researchers at the University of Missouri developed a novel approach to nanofabrication on biological surfaces using frozen ethanol as a protective layer. The team sought to overcome a significant limitation in traditional lithography—the tendency of the process to damage delicate biological materials 5 .
The researchers worked with purple membranes from Halobacterium salinarum, microbes that produce a light-sensitive protein called bacteriorhodopsin that converts light into energy. These membranes are exceptionally delicate, making them ideal for testing the gentleness of the new fabrication technique 5 .
Researchers placed the biological membrane on an ultra-cold stage within a scanning electron microscope, chilling it to below -150°C to preserve its delicate structure 5 .
They introduced ethanol vapor into the chamber, which instantly froze upon contact with the cold surface, forming a smooth, thin layer of ethanol ice covering the biological material 5 .
Using a focused beam of electrons, the researchers "drew" intricate patterns onto the frozen ethanol layer, creating a template for the desired nanostructures 5 .
The sample was gently warmed, causing the unexposed ethanol ice to sublime, leaving behind only the patterned material where the electron beam had modified the ethanol 5 .
The team used surface-enhanced Raman scattering to analyze the resulting structures, discovering that the patterned material behaved similarly to carbon fiber 5 .
