Scientists Put an End To Smelly Socks
athe!st writes "A new anti-microbial treatment that can make clothing — including smelly socks — permanently germ-free has been developed by US scientists. In a paper published in the American Chemical Society journal Applied Materials and Interfaces, Dr Jason Locklin and his colleagues state that the treatment kills a wide range of dangerous pathogens, including staph, strep, E. coli, pseudomonas and acinetobacter."
another way to breed resistant strains of dangerous pathogens.

Am I the only one who has grown cautious of putting chemicals on my skin, in close contact, for many hours of the day? We'll either end up with a super bug or foot cancer...
Much like antibiotics does this not help create resistant germs and ultimately makes some of those dangerous pathogens harder to kill? Even more so since it is constantly in contact with and battle against said pathogens?
I'll meet you at the intersection of "Should be" and "Reality"
Let's see, contribute to the creation of a superbug, or wash my fucking socks? Decisions, decisions...
Thalidomide relieved pregnant women of that pesky morning sickness--and resulted in babies born with missing limbs.
I think I'll stick with smelly socks until we've had a good 20 year run with guinea pigs who are willing to buy any spiffy new thing the chemical industry comes up with.
Why they don't want to live in the clothing, maybe they know something you don't.

Scientists have created a thing, made out of atoms, that can PERMANENTLY eliminate any possibility of other atoms being arranged in such a fashion as to inconvenience me? Huzzah!

Vinegar and rubbing alcohol will do a fine job of creating a microbe-free zone, but you might smell a bit more like sour wine than you'd like.

I've heard almost the same thing about "free energy" magnetic motors. Tell us what the chemicals are or it's bullshit.
I normally don't post on slashdot, but since this is related to my field (I am a chemist) and there have been a lot of comments about how bad this must be because of the possibility of building resistance, I felt obligated to clarify this after looking into it.
As far as anti-microbial substances work, this is about as simple as it gets. All bacteria have cell membranes consisting of a lipid bilayer - it's basically two layers of negatively-charged water-loving stuff attached to a fatty part in the middle that stays away from water. This treatment uses a polymer that can pass through the cell membrane, with positively-charged bits making it inside the membrane. The positively-charged parts on the polymer attract the negatively-charged parts on the membrane and cause it to come apart enough for the cell to die.
Many other antibiotics are based on small molecules that interrupting some metabolic process of bacteria. Bacteria develop resistance by making enzymes that will break down these small molecules once inside the cell. This new method attacks the outside of the cell directly, not something inside the cell. It wouldn't be impossible for bacteria to develop immunity to this, but it would be comparably very improbable.
We're all gonna die!
BAH - They've been promising this stuff for over ten years now. I remember seeing it on that show "Beyond 2000" back in '98... Still waiting for it
For justice, we must go to Don Corleone
To all the people posting about ultra-resistant super MRSA mega death bacteria forming because I crack open a bottle of Dawn occasionally, haven't you ever heard of defense in depth? Also, what about this study which suggests that a combination of antibiotics may be more effective against resistant bugs? This shit happens all the time on /. Whatever trendy counter-intuitive "wisdom" there is on a subject is repeated and subsequently shit on ad nauseum. Isn't this the home of RTFA?
While this might eliminate cleaning due to bacteria, this won't resolve the issue of dirt built up.
As to socks, just wear sandals :)

47 comments and no one noticed that the link was broken? Sure there's a BBC link, but it tells you exactly nothing. Doesn't even tell you what it is. I know slashdotters seldom read the articles, but come on.

No it's the home of telling other people to RTFA, or pre-posing a statement with the admission that you haven't. Sometimes both.
That's why I only use natural ingredients in my shoe deodorizer: onions and peaches.

or in other words permanently free of germs that haven't developed resistance to another potential treatment for when they make you sick.

Okay here's a semi-secret which shouldn't be so secret. I use something called PitRok Crystal Deodorant (perhaps try this if you're US based), but any Ammonium Alum based deodorant will be good. It's meant for the armpits, but I find it works good on feet too. 5 stars on Amazon.co.uk by almost everyone including me.
I only wish I knew about this sooner. It's completely odorless and nonsticky, which is great, but also lasts over a year (you wet its hard crystal tip and apply). Anybody who benefits from this, feel free to buy me a beer or 10 according to how generous you feel.

The antimicrobial action is hypothesized to be largely physical (disruption of the cell membrane leading to cell death). Barring some relatively significant mutations that greatly change the overall structure of the bacteria, a "resistance" would be relatively unlikely.

Abstract:
One-Step Photochemical Synthesis of Permanent, Nonleaching, Ultrathin Antimicrobial Coatings for Textiles and Plastics
Antimicrobial copolymers of hydrophobic N-alkyl and benzophenone containing polyethylenimines were synthesized from commercially available linear poly(2-ethyl-2-oxazoline), and covalently attached to surfaces of synthetic polymers, cotton, and modified silicon oxide using mild photo-cross-linking. Specifically, these polymers were applied to polypropylene, poly(vinyl chloride), polyethylene, cotton, and alkyl-coated oxide surfaces using solution casting or spray coating and then covalently cross-linked rendering permanent, nonleaching antimicrobial surfaces. The photochemical grafting of pendant benzophenones allows immobilization to any surface that contains a C–H bond. Incubating the modified materials with either Staphylococcus aureus or Escherichia coli demonstrated that the modified surfaces had substantial antimicrobial capacity against both Gram-positive and Gram-negative bacteria (>98% microbial death).

Given microbes can survive high temperature thermal vents, concentrated heavy metals in mining waste ponds, high pressures a mile underground, low pressures and cosmic rays in space, etc, I would say it's probably only a matter of time.

I mean, what gives?
And its been bothering me. I mean have you seen those hand gels people are always slathering on? They seem to forget the .1% that it doesnt kill. Its like, congrats, you just made your hands a cess pool by removing all the competition a microbe that is already resistant to our best efforts would normally have!
The only thing that nears that level of stupidity would be preemptively dosing all our herd animals with anitbiotics by default. But thats so insanely reckless that theres no way wed ever allow it. ...We do? Oh. Thats not good. :/
we could have kicked unemployment down by a couple ten-thousand by hiring people to wash scrubs and keep things clean, and at the same time reduced bacteria in hospitals, which would have prevented countless infections (actually not countless, some people have done studies on this type of thing).
but no. fuck that. lets fire all the janitors and clotheswashers and invent weird new chemical experiments that probably might work maybe, because some investment banker needs to pay-off the maserati he wrecked on his last coke and whore binge.

Wool does this naturally.... it's microscopic physical structure is such that bacteria has a difficult time attaching to it physically. When I switched to wool socks I permanently eliminated smelly feet, and they're much more comfortable even in hot weather. Once again, scientists develop a "novel" solution to a problem nature solved much more elegantly long ago. Wool literally evolved for the explicit purpose in which humans use clothing for: keeping mammals comfortable and healthy in a wide range of climates... and it has a complicated structure that gives it unique properties to this end that have yet to be replicated by synthetics.
I doubt any amount of evolutionary pressure could enable you to swim in a diarrhea swimming pool.
HI I'M JOHNNY KNOXVILLE AND THIS IS MY DIARRHEA SWIMMING POOL!!!
I'd be pretty impressed if they evolved past that impediment
- Mycobacteria (as those causing Tuberculosis) have thick reinforced waxy cell walls, which can withstand alcohol, for example.
- P. Aeruginosas also protect themselves (polysaccharids and biofilms) and have evolved to be able to digest quite a lot of organic compound. They'll resist alcohol, and try drinking it too.
- not a living bacteria, but lots of bacterial spores can withstand a crazy vast amount of abuse, and stay unharmed (that the whole point of spores).
And for whatever other physical hard-limit you may dream of (and which should effectively kill most of the regular bacteria), there is always bound to exist some obscure extremophile able not only to survive, but thriving in these extreme conditions.

When friends taste my homebrew, they sometimes ask me how I got the alcohol in there. I tell them that the yeast eats the sugars, pisses alcohol and farts carbon dioxide. For some reason, that I can't fathom, they loose their appetite for my brew at that point.

Any just how am I suppose to discern which of my clothes are good-to-go that morning? Seriously though, this could be huge for outdoor clothing used by hikers and the like. No more smelling ripe after a week in the bush. It could also allow clothing to last longer because most of the damage it takes these days is from the washing machines. We often wash clothing that has very little actual dirt on it, but a little sweat and oil with bacteria that smells.
I know a few people i could spray this stuff in there shoes....and mine of course, but more theirs...
This is true, and I disagree with GP also. However, it can kill "good" bacteria, which is a vector for infection by more dangerous microbes.

I initially read the scientist's name as Dr. Socklin. It makes more sense that way, at least in my mind.
This could perhaps work for nasty odors! I like that idea!
I don't know about the rest of you, but my experience is that microbes may generate methanol or ethanol, but none generate isopropanol. Remember that the simplest alcohol is hydrogenol (a.k.a. dihydrogen monoxide, hydrogen hydroxide, hydric acid and water). This alcohol is necessary for life as we know it. That doesn't mean that all alcohol is good for you.
