It is found that controllable material removal at the nanometre level is possible above an ablation threshold of 250 mJ cm(-2). Contact mask printing shows well-defined features can be micromachined in this glass with sub-micron resolution capability. Micro-features produced in this way have been replicated by polydimethylsiloxane (PDMS) moulding and the stamps used to print arrays of fluorescent molecules with sub-micron fidelity.en10.1007/s00339-002-1936-0info:eu-repo/semantics/openAccessArticle7703.04.2020391394Q2WOS:000184296000009Q2
