Scanning tunnelling microscopy and molecular modelling of xanthine monolayers self-assembled at the solid-liquid interface: relevance to the origin of life.

摘要: The development of scanning tunnelling microscopy (STM) has allowed examination inorganic crystalline surfaces and their interactions with organic adsorbates unparalleled resolution. As a novel technique in origin life studies, the application STM is detailed particular attention paid to methods employed analysis monolayer structures. imaging molecular modelling self-assembled monolayers purine base, xanthine, formed on graphite molybdenum disulfide are presented as an example. putative role such structures discussed.
