Blue Tea Mediated Synthesis and Characterisation of Copper Nanoparticles: An In-vitro Study

Background: Nanoparticles (NPs) are often regarded as essential components of nanotechnology. Butterfly-pea flower tea, often known as Blue Tea, is a caffeine-free or herbal tea produced from an infusion of the Clitoria ternatea plant's flower petals. In the creation of nanoparticles, plant extracts may act as reducing and stabilizing agents.

Aim: The study's goal was to evaluate the characterization of copper nanoparticles derived from blue tea.

Materials and Methods: The green synthesis approach was used to make the blue tea mediated copper nanoparticles. UV spectrometry and transmission electron microscopy were used to examine morphological characteristics such as form and size of the green produced copper nanoparticles.

Results: The results revealed that the nanoparticles mediated by blue tea extract were eco-friendly, excellent, and non-toxic. Copper nanoparticles were well disseminated and crystalline in nature, according to TEM pictures. Copper nanoparticles were spherical in shape. The particles were 5-10 µl in size. The TEM image showed that nanoparticles were not mixed, but were separated by equal interspaces between them, as validated by microscope visualization at a greater resolution.

Conclusion: Using blue tea, a simple, biological, and low-cost method for the manufacture of copper nanoparticles was developed in this study. To determine the efficacy of these nanoparticles, the generated copper nanoparticles can be exposed to several biological activities such as antibacterial, antifungal, and cytotoxic evaluation.
