Seminar on antibacterial nanometric material will be held on September 26.

Septembre, 26. With an open talk to the academic community, Cedenna specialists will show progress in the development of hollow nanostructures of antibacterial material with potential use in the area of ​​food or biotechnology.


In order to continue bringing its research closer to the entire community, the Center for the Development of Nanoscience and Nanotechnology (Cedenna) of our University has organized a series of talks open to students, academics and the general public.
The next edition of these meetings will be held on Thursday, September 26, at 4:30 p.m., in the auditorium of the Research Building and will be presented by researchers Ana Carolina López De Dicastillo and Juan Escrig Murúa.
The scientists will present a project carried out by Cedenna, in addition to the results of a multidisciplinary Fondecyt project, on the development of nanostructures applicable in areas such as health or food preservation.
Specifically, the research focuses on the development of nanostructures in different ways from the technique of electrospinning and deposition of atomic layers (ALD).
“What we did in Cedenna – explains Dr. Escrig, advancing what will be addressed in the talk – was to take a nanosphere produced with electrispinning and cover it with the technique of deposition of atomic layers or ALD for its acronym in English, in which We are specialists”.
The electrospinning or electro-spinning technique – in which Dr. López de Dicastillo works – allows the manufacture of polymeric structures, with shapes of fibers or spheres, achieving a nanometric scale material, which at first glance resembles a thin tissue.
“What we did from Cedenna – explains Dr. Escrig, advancing what will be addressed in the talk – was to take these polymers and coat them with a technique called deposition of atomic layers. This is a very powerful technique and the Nanomagnetism Laboratory is the only group in Chile that has a team with the characteristics to develop it, therefore, we have a comparative advantage, ”says the researcher, adding that the idea is that the nanometric spheres “Can be coated with various materials. In particular we coat them with titanium dioxide, which has antimicrobial properties. ”
Interdisciplinary work
Cedenna’s work is approached from different disciplines, therefore, the organizers of the talk point out that “everyone is invited.” Both researchers represent the work from their perspectives, Ana López de Dicastillo is a specialist in food chemistry and technology, while Juan Escrig is a physicist.
“Some attendees may be interested in their synthesis process, others in characterization techniques, they may be interested in their physical or antimicrobial properties, or their potential applications in the area of ​​food or medicine; therefore, all students, academics and the general public are invited, ”says the Cedenna researcher.
For her part, Dr. De Dicastillo has focused on the development of metal oxide or metal nanostructures from electrospinning technique and points out that during the talk she will refer to the studies of these structures, both nanotubes and nanospheres, with activity antimicrobial that may have use in the food packaging industry.
