Using nano-sized spheres as a starting point,
researcher Juan Wang of the University of Twente (MESA+ Institute)
creates fascinating structures that can have a wide range of shapes
and functionalities. They can even achieve a beautiful flower-like
appearance with nanowires connected by gold nanospheres. The new
nanostructures can be designed for detecting chemical or biological
substances at their surface. They have unique optical properties
and can also mimic a biological surface that attracts or repels
water.
