Abstract

The Front Cover illustrates a microdroplet formed in a temperature responsive ionic liquid aqueous solution under the laser irradiation. Upon focusing a near-infrared laser beam onto the glass/solution interface, a single liquid droplet is formed due to optical trapping and a photothermal effect. The resultant droplet deposits on the substrate, exhibiting a hemispherical shape. The hemispherical droplet can extract and condense molecules due to high ionic liquid concentration, which is confirmed by Raman and fluorescence spectroscopic analysis. The current approach offers a new methodology with which to collect and perform microanalysis on tiny amounts of substances. More information can be found in the Research Article by Ken-ichi Yuyama and co-workers (DOI: 10.1002/cptc.202400394).

封面:用光镊在温度响应离子液体中形成半球形液滴(ChemPhotoChem 5/2025)
前盖示出在激光照射下在温度敏感离子液体水溶液中形成的微液滴。当近红外激光束聚焦到玻璃/溶液界面上时,由于光捕获和光热效应,形成单个液滴。所产生的液滴沉积在衬底上,呈半球形。由于离子液体浓度高,半球形液滴可以提取和凝聚分子,拉曼光谱和荧光光谱分析证实了这一点。目前的方法提供了一种收集和对微量物质进行微量分析的新方法。更多信息可以在kenichi Yuyama及其同事的研究文章中找到(DOI: 10.1002/cptc.202400394)。
