Abstract
This is the first-ever report on the effects of curcumin concentration (10, 20, 30, 40, and 50 µM) and reaction time (10 min, 2 h, 5 h, 24 h, and 48 h) on the synthesis of curcumin–copper phosphate hybrid nanoflowers. The size of the nanoflowers varied (7.154 ± 2.75 µm to 11.43 ± 2.85 µm) with different concentrations of curcumin and the reaction time also affected the size (9.54 ± 1.45 to 34.05 ± 4.46 µm). UV-Vis spectroscopic analysis confirmed the mechanism of formation of the nanoflowers. Fourier transform infrared measurements showed characteristic infrared vibration modes (v1, v2, v3, and v4) of PO43− ion. Crystalline nature of the nanoflowers was confirmed from X-ray powder diffraction analysis. The confocal laser scanning microscopic analysis showed intrinsic green fluorescence of curcumin. The fluorescent nanoflowers have very good scope for application in the field of curcumin-labeled tracking technology.
