The Sound of Smallness

Researchers from the Massachusetts Institute of Technology, USA have introduced a simple strategy for making nanoparticles by the sonofragmentation of high‐aspect‐ratio 1D substrates.

Particle Micromotors

Magnetically steerable, acid-resistant micromotors are developed that can be fabricated by electrostatic attraction between magnetite nanoparticles and gold microrods at pH ≈ 4.
