In the seven days of the “Advanced school on modern trends of Biophotonics for diagnosis and treatment of cancer and microbial control”, Dr. María José Gallardo was able to learn the latest advances in Photodynamic Therapy (PDT). At the meeting held on April 11 to 19 in the city of Sao Carlos, Brazil, also she presented a poster with some of his research.
The Institute of Physics of São Carlos was the location for the meeting all those working in the area of photodynamic therapy in the world. “With the visit of Professor Vanderlei Bagnato last year, in CEFOP we saw the general and interdisciplinary too. Now deepened in all subjects, from the most basic physics until field application of PDT in an african village. Physics, Biochemistry, Medicine, medical specialties, also a bit of public health were some of the treated areas. Was discussed for example, why if is this treatment is cheaper, more effective than another, it isn’t so massive”.
Particularly, Dr. Maria José is interested in the biochemistry behind the PDT treatment, a discipline in the middle of Biology and Physics. “I want to work on the interaction between physicists and biologists that is what I do in CEFOP well. I talked to teachers of Biochemistry and Physics Institute of Sao Carlos, and we stay in contact to write a project together and start a collaboration both for me or anyone in our center can spend a long time working in Brazil, and that one of its researchers spend time here”, she said.
The poster that the researcher presented was titled “Implementation of Optical Techniques in Microbiology”. It explains biophysical applications performed in our Center and all the topics that she works with microscopy and optical tweezers. “I received many questions. He approached a teacher from Italy who works on control of microorganisms applied to the PDT, then as a part or the poster that were partly showed that theme, we talked a lot. She was interested in remote sensing, corresponding to what we do with hyperspectral cameras. Optical tweezers was another aspect consulted. The assistants found it very interesting and now are many people eager to learn and incorporate this into the methodologies they use”.
Brazil is one of the most developed countries in science in Latin America, and specifically there is an organism, FAPESP, responsible for give funding to the state of Sao Paulo. “Just as in the United States and Europe, there are cities like Sao Carlos that revolve around the university and technological developments. It’s a small town, where most people are related in some way to the campus, and there are university-related companies that generate income and resources. It’s understood as important to invest and work in science and technology”, said the researcher.
She added that the investment of resources in this school, as Thorlabs and SPIE sponsors, it’s something outstanding: “In SPIE there a specific division for students which promotes the generation of groups in cities around the world, who can organize activities about optical issues and bringing in international exhibitors. They emphasized much in create these organizations in each university. I knew one at the PUC (Pontificia Universidad Católica de Chile), and I find it very interesting because the students could be create some group here, with students of Physics”.
