Plasmon‐Induced Optothermal Manipulation of Colloidal Particles and Biological Entities Resilient to Saline Environments

Advanced Optical Materials, EarlyView.
The particle with high surface hydrophilicity exhibits strong thermophoretic attraction, as its dense hydration layer enhances the role of interfacial water molecules in determining thermophoretic mobility over other ionic effects. This finding elucidates the mechanism underlying the robust thermophoretic accumulation of Escherichia coli in high ...

MANGO‐“Fruitcage”: A Conditional Photocage Utilizing a Fluorescence Light‐Up Aptamer

Advanced Optical Materials, EarlyView.
Fruitcaging ‐ a proof of concept study of a conditional photocage (Thiazol‐Orange) activated upon binding to the fluorescence light up aptamer (Mango). The prolongation of the excited state lifetime explains the redirection of the reactive pathway toward photocleavage and provides a sensitive spectroscopic readout.

Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams

Advanced Optical Materials, EarlyView.
Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.
