[HTML][HTML] Particle manipulation beyond the diffraction limit using structured super-oscillating light beams
The diffraction-limited resolution of light focused by a lens was derived in 1873 by Ernst
Abbe. Later in 1952, a method to reach sub-diffraction light spots was proposed by …

Directed assembly of nanoparticles into continuous microstructures by standing surface acoustic waves
Directed-assembly by standing surface acoustic waves (SSAWs) only requires an acoustic
contrast between particles and their surrounding medium. It is therefore highly attractive as …
