Abstract

Marigold flower-like monoclinic (α)-Gd₂(MoO ₄)₃ particles with PEGylation are prepared by regrowth technology using solvothermal and hydrothermal methods. The growth mechanism of the flower-like morphology has been explained by taking SEM images of the intermediate products. SEM images of the calcined products displayed their visible pores and confirmed the stability of flower-like texture. PEGylation of α-Gd₂(MoO₄)₃ and stability of PEG in the complex system have been verified by means of Fourier transform infrared spectra and X-ray diffraction patterns. The nitrogen adsorption-desorption isotherms of PEGylated α-Gd₂(MoO₄)₃ particles established their mesoporous nature, and these mesoporous particles exhibited gorgeous red emission when exciting with UV or visible wavelengths. The synthesized particles show both hydrophilic and hydrophobic nature, depending on the stability of PEG and calcination temperature. The hydrophilic particles have the capacity to penetrate cells, translocate to the nucleus, and trigger high-quality signals from the cellular compartment.
