Claim 17:
18. A method of detecting a pathogen, the method comprising:
capturing a pathogen via a filter from a volume of gas flowing through the filter, the filter comprising:
a metal substrate defining a plurality of apertures configured to allow the gas to pass through the apertures, the metal substrate comprising a metal alloy, the metal alloy comprising a first metal and a second metal; and
a plurality of carbon nanotubes on a surface of a first phase precipitated out from a second phase of the of the metal alloy, the plurality of carbon nanotubes configured to capture a pathogen,
wherein the first phase comprises a gamma prime phase of nickel or cobalt, wherein the gamma prime phase of the nickel or the cobalt is part of a structure of the metal substrate; and
detecting, via a detector, the at least one pathogen captured by the filter.
