Crystal nanoflowers and the future of architectural chemistry (w/video)

In this video, follow Harvard researchers Wim L. Noorduin and Joanna Aizenberg as they break down their process, showing how they developed these crystal 'flowers' using a beaker and two chemicals, manipulating the surrounding conditions to form them. Their research could potentially change our understanding of how structures are formed in nature, which may open the door for a new approach to nanotechnology.

2D transistors promise a faster electronics future

Faster electronic device architectures are in the offing with the unveiling of the world's first fully two-dimensional field-effect transistor (FET). Unlike conventional FETs made from silicon, these 2D FETs suffer no performance drop-off under high voltages and provide high electron mobility, even when scaled to a monolayer in thickness.

Detecting glucose levels in saliva with nanoscale interferometers

Researchers have developed a new biochip sensor that can selectively measure concentrations of glucose in a complex solution similar to human saliva. The advance is an important step toward a device that would enable people with diabetes to test their glucose levels without drawing blood.
