  • ee venom contains a potent toxin called melittin that can poke holes in the protective envelope that surrounds HIV
  • When the nanoparticles come into contact with normal cells, which are much larger in size, the particles simply bounce off
  • an advantage of this approach is that the nanoparticle attacks an essential part of the virus' structure. In contrast, most anti-HIV drugs inhibit the virus's ability to replicate
  • ...1 more annotation...
  • The nanoparticles could be injected intravenously and, in theory, would be able to clear HIV from the blood stream

  • the tiny sponges mimic red blood cells, and are able to soak up lethal toxins – including snake venom and bacteria – from the bloodstream.
  • The nanosponges are made up of a biocompatible polymer core, which is coated with segments of the host’s red blood cell membranes.
  • each nanosponge is 3,000 times smaller than a red blood cell
  • ...2 more annotations...
  • So many of the nanosponges are injected that they end up actually outnumbering the real red blood cells in the bloodstream. This results in the majority of the toxins attaching themselves to the sponges, leaving most of the blood cells alone.
  • The project was led by Prof. Liangfang Zhang, and described in a paper recently published in the journal Nature Nanotechnology

    As I'm working on my presentation, I came across this article. I thought it was very interesting considering what I'm presenting on releases two very potent toxins into the bloodstream and ultimately leads to death.
