WebOptical trapping-induced crystallization (OTIC) was first demonstrated by Sugiyama et al. in 2007 by focusing a near-infrared (NIR) laser in supersaturated glycine/D 2 O solution. When a laser beam is tightly focused in solution, optical gradient force attracts particles toward the focus spot [cf. optical trapping in Rayleigh regime described ...

In both cases, when laser …
WebVarious approaches including laser induced crystallization technique has been reported to tackle this issue. We report on the crystallization of small- and macro-molecules under focused optical radiation from a femtosecond laser (λ = 800 nm). The efficacy of this technique is proved by crystallizing different samples such as sodium chloride ... WebApr 14, 2024 · Polymer gels are usually used for crystal growth as the recovered crystals have better properties. Fast crystallization under nanoscale confinement holds great benefits, especially in polymer microgels as its tunable microstructures. This study demonstrated that ethyl vanillin can be quickly crystallized from carboxymethyl …
