Wearable Nanotech Could Combat Nerve Agents (phys.org) 24

Posted by BeauHD from the wearable-detox dept.
alternative_right shares a report from Phys.org: Nanoparticles could someday provide a new way to help soldiers fight back against deadly nerve agents on the front lines. In a new study, Northwestern University scientists developed a nanoparticle-based compound that, when mixed into clothing dyes, could limit the impact of chemicals commonly found in pesticides, insecticides and nerve agents. Manufacturers could potentially add the nanoparticles to clothing used by those most at risk, such as farmers' masks and gloves or soldiers' uniforms and tactical gear. Or, if someone is exposed to a potentially deadly chemical, they could spray their clothing with water mixed with the compound to deactivate the chemical before its damaging effects take hold. The study has been published in the journal ACS Nano.

  • It says "combat" and "fight back", but it seems like it just protects the user and does nothing to retaliate.

      If you are going to nitpick then at least verify your complaint is accurate.

      In this case, "combat" is being used as a transitive verb and if you make a quick check to any dictionary [merriam-webster.com] you will notice there is an applicable definition.

      transitive verb
      1: to fight with : battle
      2: to struggle against
      especially : to strive to reduce or eliminate (e.g. combat pollution)

      So "combat" and "fight" merely mean it is working to neutralize the nerve agent.

        It's the "fights back", particularly combined with "back", that makes it seem incorrect. The "back", to me, implies more than just reduction or elimination. Maybe I'm wrong.

  • Longevity and specificity? (Score:3)

    The fact that this approach is catalytic rather than requiring a binding agent seems positive in terms of longevity and not being directly depleted by repeat exposure; but I'd be curious how durable the material is under real-world conditions(clothing that gets hard wear tends to get hard washes) and also how specific it is. 'Organophosphate' means something moderately specific in the context of chemical warfare; but a lot of fairly prosaic compounds are, technically, 'organophosphates'(like DNA and RNA when held together by phosphodiester bonds); and this would be considerably less helpful in practice if it is busy chewing up the genomes of random soil bacteria; and markedly less helpful in practice if there's a "do not perturb the nanites in your clothing if you want them to not migrate into your cells and start mitigating the harmful effects of your DNA" user notice on the treated article.

    Chems are horrid but one can dress for them.

    Nerve agent like other war gases degrades opponents by forcing them to wear CBRN ensembles which are miserable to work and fight in. (Gas is so nasty not even Hitler used it in combat because he'd personal experience in WWI.)

    Modern CBRN suits are (barely) breathable because they can filter contaminants. Suits which even partly neutralize nerve agent would not just save lives but reduce misery. Gases are frequently inefficient even when used on undefended targets like Saddam Hussein's bombing of Halabja (which took multiple sorties to execute).

    A chem suit fabric that can neutralize contamination could save lives and usefully decrease exposure. Chems don't magically wipe out everyone exposed. The 1995 Tokyo subway attack affected several thousand people while only causing ~14 direct fatalities among a concentrated, defenseless group. Neutralizing fabric would be very useful against highly diluted agents.

    When I first joined the Army, we were still issued the M13 Individual Decontaminating and Re-Impregnating Kit. A few bags of powder you would use on your equipment and clothing to decontaminate yourself. Always freaked us out that we would have to us it after we were contaminated. MOPP gear came later and was much better protection. M13 - https://gasmaskandrespirator.f... [fandom.com]

    • We got M13 in the early 1980s to use in exercise (aircraft hydraulic fluid simulated agent since the strips were basically PH test strips similar to those used in swimming pools) and wore the olive green CPOG with flappy overboots (until someone figured out rain boots were better in every way and not prone to holes).

      The later gear is much comfier, and unlike M17 masks troops don't have to remove a contaminated mask to replace filters....
