A dedicated "exhausted enclosure" should be considered for nanomaterial work, rather than a chemical fume hood. Think PCR enclosure.

Luis is correct, low flow down as low as 50LFPM would be best working with nano-materials.

For nanomaterial work, it may require a lower fpm than the 80-100 fpm. Check with the fume hood manufacturer for proper face velocity if this is the case.
