Abstract

Nowadays, microfluidic synthesis has many advantages over bulk synthesis. By controlling the flow into the microfluidic chip, we can synthesize nanoparticles with defined and precise characteristics. A continuous microfluidics synthesis of CaWO₄ was conducted to obtain nanoparticles with a Scheelite structure approximately 10 nm in diameter. The CaWO₄ nanoparticles were characterized using elemental composition, chemical structure, particle size distribution, and morphology. Calcium tungstate and its derivatives are well known for their optical properties and have great potential for medical applications. The small diameter of nanoparticles allows the synthesis of composites on their basic for theranostics in cancer treatment. Our work indicates the potential opportunity of a continuous microfluidics technique for the rapid fabrication of Scheelite-type tungstate.

Graphical abstract

Microfluidic synthesis of CaWO₄ nanoparticles with a Scheelite structure using a continuous process yielding 10 nm particles. Characterization includes elemental composition, structure, and morphology. This substance has potential applications in photodynamic therapy because of its optical properties.

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
