The Faculty of Dentistry at Universitas Gadjah Mada (FKG UGM) held a training session on the use of the Particle Size Analyzer (PSA) and Zeta Potential at the Integrated Research Laboratory (LRT) on 22 August 2023. This event was conducted to enhance the competency of laboratory staff.
drg. Trianna Wahyu Utami, MDSc., Ph.D., Vice Dean for Research, Community Service, and Collaboration, stated that this training aims to help researchers understand the principles and functions of the equipment, including sample preparation and data interpretation.
The speaker for this event, Wiji Rahayu, explained that the Particle Size Analyzer (PSA) and Zeta Potential are useful for measuring particles from nano to micro sizes and analyzing particle charge through zeta potential. “This tool can measure particles ranging from 0.3 nanometers to 10 micrometers,” said Wiji.
This instrument allows for the analysis of particle size distribution in terms of intensity, number, and volume, utilizing two types of scattering angles, and is equipped with features that display the aggregation index of the sample. This facilitates the comparison and analysis of data resulting from tests.
In the context of dentistry, the Zetasizer is used for biomaterial analysis, saliva research, and evaluation of restorative materials and drug delivery systems. Understanding zeta potential is crucial for knowing the interactions of materials with tissues, dispersion stability, and other characteristics vital for the development of new materials and therapies.
The Faculty of Dentistry at UGM regularly conducts training sessions to enhance the capabilities of its human resources. This training is expected to foster innovation in research within the field of dentistry.
