The National University of Córdoba (UNC) acquired a microscope that allows viewing biological material up to 80 nanometers (nm). It is used for scientific research, in the area of cell biology and medicine, and to provide services to the private sector. It is, so far, the only one in the province of Córdoba, and one of the few in Argentina.
This resolution is classified as one of the best, which allows more accuracy and better studies in the fields of biological analysis.. It was purchased and installed through a subsidy for Large Equipment from the Ministry of Science and Technology (Secyt).
Due to the way its lasers work, this highly complex scientific technology focuses on samples that have a fluorescent molecule that restricts the area to be observed and achieves a resolution up to six times greater than a conventional microscope, making it visible clearly. detail particles up to 80 nm in diameter.
According to the Center for Micro and Nanoscopy of Córdoba (Ceminco), this type of microscopy allowed crucial advances in the world in the understanding of cellular processes such as endocytosis, exocytosis and intracellular signaling. In biomedicine, STED microscopy is used to study neurodegenerative diseases, cancer, viral infections and other pathologies, providing valuable information for the creation of new therapies.
The device in question required an investment of 250,000 euros, and was installed in September 2023 in the Ceminco building. All work linked to nanosciences demands this technology, such as the characterization of nanostructures, the distribution of nanoparticles or the study of interaction at the nanometric scale.
Meanwhile, in industry, STED microscopy is used for quality control of pharmaceutical products, medical devices and high-tech electronic components.
Carlos Mas, member of Ceminco, stated: ““STED microscopy offers more than six times greater optical resolution than confocal microscopy (…) revealing aspects that were previously hidden from our view,”
The center in charge offers this STED microscope to the entire scientific community and the private sector. Use of STED microscopy can be rented for very affordable rates, ranging from $16 per hour for UNC users to $32 for the private sector.
