AI Article Synopsis
- Dynamic control over gold nanorods in liquid crystals is achieved through microscale ring confinement, allowing for unprecedented manipulation at the nanoscale.
- By adjusting elastic energy with temperature changes, this method can reversibly capture nanoscale particles, improving flexibility in material properties.
- This technique results in significant shifts (over 100 nm) in the surface plasmon resonance peak, outperforming previous research on gold nanorod composites.
Article Abstract
Unprecedented, reversible, and dynamic control over an assembly of gold nanorods dispersed in liquid crystals (LC) is demonstrated. The LC director field is dynamically tuned at the nanoscale using microscale ring confinement through the interplay of elastic energy at different temperatures, thus fine-tuning its core replacement energy to reversibly sequester nanoscale inclusions at the microscale. This leads to shifts of 100 nm or more in the surface plasmon resonance peak, an order of magnitude greater than any previous work with AuNR composites.
