Abstract

CeO2 nanoparticles are biomaterial that demonstrate potential as antioxidant and radioprotector for medical application. In this study, the radioprotector properties of CeO2 nanoparticles was evaluated by measuring absorbed dose of X-ray radiation. CeO2 nanoparticles were synthesized by precipitation and characterized using UV-Vis and FTIR spectrometers. CeO2 nanoparticle solution was prepared with various concentrations from 0.005 mg/mL to 0.06 mg/mL. The solution was exposed to 6 MV X-ray photon beam from medical linear acceleration with a source-to-surface distance of 100 cm and radiation dose of 2 Gy. The absorbed dose of X-ray by CeO2 nanoparticle solution was measured by an ion chamber detector. The absorbance peak at 301 nm observed in UV-Vis spectrum and absorbance peak at 854 and 492 cm-1 in the FTIR spectrum confirmed the formation of CeO2 nanoparticles. Radiation dose measurement exhibited dose reduction of CeO2 nanoparticles solution depend on concentration. CeO2 nanoparticle solution with concentration higher than 0.04 mg/mL showed potential application for radioprotector 6 MV of X-ray photon beam.

Abstract

The use of gold nanoparticles is being studied more widely, including in the medical, electronics and sensor fields. Nanoparticles with high concentration and purity can be produced using the pulsed laser ablation method. This study aims to increase the concentration of gold nanoparticle colloids linearly with increasing ablation time using Nd: YAG Laser. The colloid concentration test parameters based on The concentration of AuNPs colloids with 10 minutes, 15 minutes, and 25 minutes ablation time is 5.17; 8.50; and 20.12 mg/L. It can be concluded that the longer ablation time succeeded in increasing the absorbance value and ultimately increasing the concentration of gold nanoparticle colloids. Nanoparticle colloid concentration can be further investigated using synthesis methods other than pulsed laser ablation.

Abstract

Colloidal TiO2 nanoparticles were synthesized via pulsed laser ablation in liquid (PLAL) method using a Q-switched Nd:YAG laser operating at 1064 nm. The optical and structural properties were analyzed using UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), and selected area diffraction (SAED). The amorphous TiO2 colloids exhibited a distinct absorption edge in the UV region, with the optical bandgap (Eg) estimated by the Tauc plot to be approximately 3.75 eV. Photocatalytic activity was evaluated through the degradation of Rhodamine B (10 ppm) under UV lamp (254 nm) irradiation. The TiO2 photocatalyst achieved more than 75% degradation within 150 minutes, whereas the control (photolysis without catalyst) showed less than 5% degradation. These results demonstrate that PLAL enables a clean and straightforward synthesis of high-purity amorphous TiO2 nanoparticles with effective photocatalytic activity under UV irradiation.
