It feels like to me that this is always the hardest part, so there's really not much to see here until that passes.

Fuck off, Yahoo

I read in the comments that something similar to this has already been invented.

I would be interested to know what the infection potential would be; if it seals the wound, would that potentially seal in any infectious agents? Presumably you'd irrigate prior to usage, but it's still an interesting question. Also, would the algae involved act similar to an agar, thus providing more opportunity for infection. I wonder if the gel could be treated with an antibacterial agent.. Interesting invention!
