We report the use of laser-pulled quartz nanopipettes as a new platform for microfabricated nanopores. A quartz nanopipette is prepared on a laser puller and <i>sealed closed prior to focused-ion beam (FIB) milling</i>. A quartz nanopore can then be FIB-milled into the side walls of the sealed pipette and used to analyze single nanoparticles. This method is fast, reproducible and creates nearly cylindrical nanopores in ultrathin quartz walls with controllable diameter down to 66 nm. Both pore si ...[more]
