Nano Letters 4(7): 1333-1337.1530-6984http://nrs.harvard.edu/urn-3:HUL.InstRepos:3109363Atomic layer deposition of alumina enhanced the molecule sensing characteristics of fabricated nanopores by fine-tuning their surface properties, reducing 1/f noise, neutralizing surface charge to favor capture of DNA and other negative polyelectrolytes, and controlling the diameter and aspect ratio of the pores with near single Ångstrom precision. The control over the chemical and physical nature of the pore surface provided by atomic layer deposition produced a higher yield of functional nanopore detectors.en-USJournal Article10.1021/nl0494001
