One-Pot Silver Nanoring Synthesis

Nanoscale Research Letters, 2009
Silver colloidal nanorings have been synthesized by reducing silver ions with NaBH4 in trisodium citrate buffers. pH increase, by addition of NaOH, was used to speed up reduction reaction. The UV–vis absorption spectra of resulting silver nanorings

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

Advanced Materials, Volume 38, Issue 30, 27 May 2026.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...
