The evolution of dynamic processes in graphene-family materials are great interest for both scientific purposes and technical applications. Scanning electron microscopy transmission outstand among the techniques that allow observing controlling such real time. On other hand, functionalized graphene oxide emerges as a favorable candidate from an investigation due to its distinctive properties, encompass large surface area, robust thermal stability, noteworthy electrical mechanical properties after reduction. Here, we report on studies structure adsorption dynamics L-Cysteine electrochemically exfoliated oxide's basal plane. We show beam irradiation prompts amorphization along with formation micropatterns controlled geometry composed L-Cysteine-Graphene nanostructures. growth predetermined arrangement well disorder induced by e amorphization, turn potentially offering tailored functionalities paving way potential applications nanotechnology, sensor development, engineering. Our findings demonstrate can cover provide control positioning emerging microstructures about 10–20 μm diameter. Besides, Raman SAED measurement analyses yield above 50% material. results our technique enables direct creation eliminating need complicated mask patterning procedures.
