The ability to sequence DNA has opened up the possibility of personalised medicine uniquely tailored to an individual’s genetic make-up. Optical sensing could provide the high-throughput DNA sequencing that would help make personalised medicine practically viable, but these approaches demand nanoporous membranes fabricated to high-level specifications that have so far only been achieved with painstaking single-pore drilling. Now researchers in Stockholm have devised an etching technique for fabricating large arrays of the desired nanopores, and have demonstrated the potential for parallel optical sensing of biomolecules….
