Studying DNA-Directed Nanoassembly, Hybridization and Mismatch-Discrimination via Plasmon Scattering of Gold Nanoparticles
… to improve the sensitivity and selectivity, magnetic microparticles (MMP) with superparamagnetism were employed in the LSPR-assisted target DNA detection. The ultrabright non-bleaching plasmonic scattering from nAu allowed direct quantification without the need for additional signal …

Continuous flow processes on single magnetic and diamagnetic particles in microfluidic devices
Magnetic microparticles have seen increasing interest in (bio)chemical processes in recent years due to their various surface functionalities, high surface-to-volume ratio, small sizes, and ease of manipulation via magnetic fields. However, conventional reactions and assays that use magnetic …

Controlled synthesis of magnetic particles
Magnetic particles have been used for many applications demanding a broad range of particles morphologies and chemistries. Superparamagnetism is advantageous over ferromagnetism because it enables us to control and recover magnetic nanoparticles during and after chemical processing. …
