The aim of the proposed research is creation of atomically thin membranes from single- and double/layered graphene with smart functionalized nanopores, which can be externally tuned by light, temperature and magnetic field (MF). The controlled perforation will be realized usány oxygen plasma, fast electrical pulses and by Ar ion bombardment. Modification of the nanopores will be done by hydrogenation or fluorination in gas phase and by functionalization with aktive molecules. The key methods for studying the nanopores are surface/tip enhanced Raman spectroscopy (SERS, TERS). Thermal/MF responsivity of membranes, and spin manipulation at the pore edges will be addressed in cryomagnetic environment using SERS and atomic/ magnetic force microscopies. Photo-response of the nanopores will be tested by conductivity measurements and by the TERS. The main output of the research is creation of novel types of atomically thin membranes with externally driven functionalities with large application potential (DNA sequencing, desalination, separation, cryoswitches, magnetophoresis).
