A nano-lollipop?  This is a tiny glass ball on a tiny stick made of polymer, a partially-completed nano-sized chemical sensor made by then-grad-student Matthew Chen.  It’s on its way to becoming a nano-torch [] , which can detect minute concentrations of chemicals due to


This is a nanotorch, which is an ultra-sensitive chemical detector, thanks to its ability to concentrate light.  In the intense light fields at the torch’s top, a normally-weak light-based chemical fingerprinting technique (Raman spectroscopy) becomes millions of times stronger.  More-sensitive Raman fingerprinting can allow us to detect trace contaminants
