Quartz-substrate-based nanopore.
(a), A schematic diagram of a quartz-substrate-based nanopore device consisting of a micrometer-sized pore in a quartz substrate and few nm-thick free-standing SiNx membrane. The SiNx membrane was transferred to the quartz substrate using the “fishing method”. Optical microscope image of micrometer size pore formed in quartz (b), before membrane transfer and (c), after the SiNx membrane transfer. (d), TEM image of a 1.5-nm-diameter nanopore drilled by a highly focused electron beam in TEM.
