Fluorescent silicon nanoparticles (SiNPs) might be one of the excellent candidates for use as optical markers in biological profiling and diagnostic applications. To exploit this perspective, they ought to be essentially synthesized from any green precursor rich in silicon. Stable dispersibility in water along with prolonged luminescence under different conditions is also desired. Moreover, one of the main challenges is to produce such optically (photoluminescence) stable and water-dispersible SiNPs. In our present work, we have reported the synthesis of a highly stable silicon nanoparticle aqueous suspension via a single-step microwave-assisted facile green route. Our as-prepared SiNPs exhibit inherent stable dispersibility, strong fluorescence, and photo-stable behavior. The experimental results demonstrate that the synthesized SiNPs are highly suitable for the detection of Fe(III) ions. This optical sensing study opens a new avenue for use of SiNPs as a valuable optical probe in chemosensory applications. Our results provide a single-step methodology for the synthesis of highly stable SiNPs from a biological precursor, which can be used as a promising tool for various chemical and biological applications.

Equisetum arvense 中硅纳米粒子的简便绿色合成,用于基于荧光的 Fe(III) 离子检测

荧光硅纳米粒子 (SiNPs) 可能是在生物分析和诊断应用中用作光学标记的优秀候选者之一。为了利用这一观点,它们应该基本上由任何富含硅的绿色前体合成。还需要在水中具有稳定的分散性以及在不同条件下的长时间发光。此外,主要挑战之一是生产这种光学(光致发光)稳定且水分散性的 SiNP。在我们目前的工作中,我们报道了一种高度稳定的硅纳米粒子水悬浮液的合成一步微波辅助的简易绿色路线。我们所制备的 SiNPs 表现出固有的稳定分散性、强荧光和光稳定行为。实验结果表明,合成的SiNPs非常适合检测Fe( III )离子。这项光学传感研究为将 SiNPs 用作化学传感应用中有价值的光学探针开辟了一条新途径。我们的结果为从生物前体合成高度稳定的 SiNPs 提供了一种单步方法,可用作各种化学和生物应用的有前途的工具。
