Living cells caught in microscopic cages for closer study

We used to think the cutting edge of tiny technology was writing "Tiffany" on a grain of rice at the state fair, but now that we’ve seen these microscopic cages for living cells, our minds are officially blown. For years researchers have worked with cells on a flat plane in petri dishes or slides. However cells live in 3-D just as we do and now researches from the Netherlands have created these nifty pyramid cages to hold living cells in place, allowing them to be studied while they function more naturally. So how do they make the cages? They deposit nitrides over silicon pits and "peel away" the walls. Whatever that means, it looks cool. [Source]
