在此,我们报告了由一类新兴材料产生的近红外 (NIR) 荧光纳米粒子,我们将其称为基于有机盐的均匀材料组 (GUMBOS)。 GUMBOS 主要是冷冻离子液体,尽管这个概念更通用,也很容易应用于熔点超过 100 °C 的固体离子材料。使用再沉淀方法制备基于源自 NIR 荧光团的 GUMBOS (nanoGUMBOS) 的纳米颗粒,并对其进行体内荧光成像评估。由于其均匀性、一步制备和复合性质,nanoGUMBOS 有助于解决替代细胞染色所固有的染料渗漏问题,并解锁这些材料的无数应用,凸显了多功能 nanoGUMBOS 令人兴奋的可能性。
Herein, we report on near infrared (NIR) fluorescent nanoparticles generated from an emergent class of materials we refer to as a Group of Uniform Materials Based on Organic Salts (GUMBOS). GUMBOS are largely frozen ionic liquids, although the concept is more general and is also easily applied to solid ionic materials with melting points in excess of 100 °C. Nanoparticles based on GUMBOS (nanoGUMBOS) derived from a NIR fluorophore are prepared using a reprecipitation method and evaluated for in vivo fluorescence imaging. Due to their uniformity, single-step preparation, and composite nature, nanoGUMBOS help to resolve issues with dye leakage problems innate to alternate cellular stains and unlock a myriad of applications for these materials, highlighting exciting possibilities for multifunctional nanoGUMBOS.
