Nearly five years ago, we obtained, with the help of FAPESP, a high-resolution electrospray ionization mass spectrometer as part of a Thematic Project. On that occasion, Prof. José Fernando Perez, who was then the scientific director of FAPESP, suggested that we attempt to create a facility system such as those existing in more highly developed countries. On that basis, we created, within the USP Ribeirão Preto School of Pharmaceutical Sciences, a system of shared use, designated the Mass Spectrometry Center. Today, the equipment, at six years of age, is in operation seven days a week year round, and provides a large number of researchers throughout the state with access to high-resolution data. In recent years, it was possible to expand that access to include more than 29 federal universities, covering the entire country. This was only possible due to planning and to the training of a specialist dedicated exclusively to the mass spectrometry facility. In the current proposal, we intend to expand this center, with the purchase of imaging equipment that is as yet unavailable in the state of Sao Paulo: the maldi-tof-tof imaging system. As can be seen in the introduction of this proposal, the capacity of this equipment will bring advancements in various fields of research. We opted for a laser with greater power and resolution, in order to provide greater support to projects in the medical field, as well as for detection in the tissues of insects, thereby meeting the needs of biologists. The expectation of identifying secondary metabolites in plant tissues and the possible correlation with their effects might provide a qualitative leap in research conducted in the state. For the biochemists who are already using normal maldi, access to such equipment will allow them to “photograph” areas of study and propose a number of mechanisms of action. As can be seen, this is perhaps one of the most universal types of equipment, and we therefore elected to gather a group of researchers from various institutions to demonstrate that this machine is suited to use in different areas and applications.
