The current nano buzz includes four innovations:

1. New research in using conductive nanomaterials for neuroengineering applications proposes carbon nanotubes as ideal probes for bidirectional interfaces in neuroprosthetics and as nanotools to endogenously (re)engineer single-neuron excitability and network connectivity.

2 Recent advance in seeded growth as the ultimate approach to producing metal nanocrystals with precisely controlled sizes, shapes, and compositions the necessary first step toward their use and assembly for large-scale applications.

3. DNA Nanotechnology in going 3D.

4. New work by a team of scientists in Korea demonstrates the position- and shape-controlled growth of nanoarchitectures using the selective growth of nanowalls with conventional lithography and catalyst-free metal organic vapor-phase epitaxy (MOVPE).
