Synthesis of cationic β-cyclodextrin functionalized silver nanoparticles and their drug-loading applications

Abstract

The synthesis of cationic β-cyclodextrin functionalized silver nanocomposites that reserve the drug loading function, which was demonstrated by inclusion interaction with thymol.

Anomalous spectral shift of localized surface plasmon resonance

“…The fac that IC molecules-AgNP interaction did not lead to substantial change in the AgNP size was confirmed by X-ray diffraction measurement (XRD) and X-ray photoelectron spectroscopy (XPS) as follows. The XRD results obtained with freeze drying of AgNPs showed characteristic peaks at 37.6° (111) and at 44.3° (200) 27 that remained unchanged between both cases of before and after addition of IC molecules (β-cyclodextrin has characteristic peak positions at 12°, 17° and 35°) 28 as shown in Fig. S2 †.…”
