Formation of quasi-stable nanostructures from L-N-stearoyl glutamic acid and its dimethyl ester on solid surfaces

The article delves into the formation of quasi-stable nanostructures from L-N-stearoyl glutamic acid and its dimethyl ester on solid surfaces. It highlights the ability of these compounds to self-assemble into various structures, such as terraces, needles, filaments, and spherical objects, depending on the solvent and concentration. The use of atomic force microscopy (AFM) allows for the direct visualization of these structures, revealing the strength of intermolecular forces that stabilize them. The study also demonstrates the dynamic nature of these nanostructures, with some objects displacing or unwinding under the mechanical action of the AFM probe, indicating their resilience and potential for practical applications in materials science and biotechnology.
