Nano-bio interactions of Gum Arabic-stabilized lanthanide-based upconverting nanoparticles: and study.

Lanthanide-based nanoparticles (Ln-NPs) are highly valued for their unique optical and magnetic properties, making them useful in various scientific fields, including materials science and biomedicine. This study investigated the use of Gum Arabic (GA), a natural, non-toxic biopolymer, as capping agent for Ln-NPs to enhance their biocompatibility and chemical and colloidal stability. Specifically, Er/Yb co-doped NaGdF Ln-NPs were modified with GA, followed by their characterization with respect to upconversion properties and as well as toxicity.
