  The particles I’m looking at are nanoparticles (called vesicles, google them!), so if I can work out a way to use them to deliver drugs, that’s one way I could make people more healthy for longer!

  There are so many different applications – from electronics, to medicine!

  One cool application is taking medication straight to where it needs to go in your body, using nano-particles, this can even be used to make chemotherapy cancer treatment more successful, so there are definitely ways it can improve all our lives 🙂
