Abstract
Herein, a simple method for etching Aunanorods@SiO2 surface to obtain Aunanorods@B-SiO2 material is reported, which is used for the theoretical study of drug loading and release of composite materials by microcalorimetry. In the presence of surfactant cetyltrime-thylammonium bromide (CTAB), the Aunanorods@SiO2 is etched under the strong acid environment with pH of about 2 to obtain the ideal material Aunanorods@B-SiO2. Relevant experimental results show that after etching, Aunanorods@B-SiO2 still retains the morphology, structure, and composition of a single material, and its LSPR absorption is almost consistent with Au nanorods. The successful preparation of Aunanorods@B-SiO2 combines the properties of Au nanorods and silicon dioxide to provide a basic material for medical cancer diagnosis and treatment.
