Abstract

Superparamagnetic Iron Oxide Nanoparticles (SPION) are iron-based nanoparticles gaining attention in the medical field due to their ability to be magnetically guided and their biocompatibility. This study aimed to explore how different homogenization speeds affect the size, distribution, and stability of SPION synthesized through the co-precipitation method. Three formulations were prepared using homogenization speeds of 1000 rpm, 3000 rpm, and 6000 rpm. The resulting particles were analyzed using Dynamic Light Scattering (DLS) to determine particle size, polydispersity index (PDI), and zeta potential. The results showed that Formula 2 (3000 rpm) produced the smallest and most evenly distributed particles (305,2 nm) with good stability. Formula 3 (6000 rpm) had a higher zeta potential, its particle size was larger and distribution less uniform. Formula 1 (1000 rpm) yielded large but more uniformly distributed particles. The results of this study show moderate homogenization speed offers the best conditions for producing SPION that are small, stable, and suitable for biomedical applications. Formula 2 shows the most promise for future development in drug delivery or magnetic hyperthermia therapies

Abstract

Abstract Knowledge about antibiotics is one of the key factors that can increase awareness for the appropriate use of antibiotics. Pharmacy students, as part of health-related academic programs, are expected to take on a role in educating the public about appropriate use of antibiotics. This study aims to assess the level of antibiotic knowledge among second-semester and sixth-semester pharmacy students. The research used an observational design with a cross-sectional approach. The study subjects were pharmacy students from the Faculty of Science at Institut Teknologi Sumatera. The research instrument was a questionnaire that had been tested for validity and reliability, and it was distributed online via Google Forms. A total of 219 respondents participated in this study. Data analysis was conducted by comparing the mean total knowledge scores between the two groups using the Mann-Whitney test. The results showed that sixth-semester students had higher knowledge scores compared to second-semester students. Statistically, a significant difference was found (p < 0.001) between the two groups. These findings indicate that the academic level influences knowledge improvement, as senior students have undergone a longer educational and academic process. Overall, pharmacy students have acquired adequate knowledge regarding the proper use of antibiotics. Keywords:  antibiotic, knowledge, pharmacy, student
