Laboratório

The Laboratory of Biomaterials and Biointerfaces (BBLab) is a center of excellence located in the Chemistry Department of the Fundamental Sciences Division of the Technological Institute of Aeronautics (ITA), in São José dos Campos - SP. This laboratory is composed of three auxiliary laboratories: the Multiuser Laboratory of Atomic and Molecular Spectroscopy (LEAM), the Laboratory of Molecular Biology (BIOMOL) and the Laboratory of Tissue Engineering and Bioprinting (LETBIP), the latter supported by ITAEx (Association of alumni of ITA). LEAM is dedicated to the characterization of materials and has state-of-the-art technology to perform atomic and molecular spectroscopic analyses. In this lab, researchers can investigate the microstructure and properties of biomaterials used in a variety of applications, from medical devices to tissue engineering materials. BIOMOL is a laboratory specialized in the preparation and investigation of biological samples. With advanced equipment, researchers can perform molecular and genetic analyzes to understand the composition and functioning of biomaterials at the cellular and molecular level. This allows the detailed study of biomaterial-biointerface interactions, as well as the identification of possible therapeutic applications. Finally, LETBIP is an innovative laboratory supported by ITAEx, dedicated to cell culture and bioprinting. Cell culture is essential to study the response of biological tissues to biomaterials, while bioprinting allows the creation of complex three-dimensional structures that can be used in tissue engineering. In this laboratory, researchers explore the biofabrication of artificial tissues and organs, with the aim of developing advanced solutions for regenerative medicine. BBLab, together with its auxiliary laboratories, plays a fundamental role in the research and development of biomaterials and biointerfaces at ITA. Its location in the Department of Chemistry at DCTA reflects the multidisciplinary approach to these studies, which involve knowledge in chemistry, biology and engineering. BBLab is a reference center in the area of biomaterials and biointerfaces, contributing to scientific and technological advances that impact health, regenerative medicine and other related areas. Through its pioneering research and cutting-edge infrastructure, the lab is at the forefront of science and continues to drive discovery and innovation in these fascinating and ever-evolving fields.

Management and Sharing of Use of Multi-user Equipment Plan FAPESP
(Fourier Transform Form Infrared Spectrophotometer)

Here we present the plan for managing and sharing the use of multi-user equipment related to a Fourier Transform Infrared Spectrophotometer (FTIR), acquired in the New Generation of Researchers Program (FAPESP Process nº 2022/03247-6), coordinated by Prof. João Henrique Lopes, from IEFQ/ITA) and in which he acts as Principal Investigator.

Description of Multiuser Equipment (EMU - ITA)

The infrared spectrometer is an analytical instrument that uses electromagnetic radiation in the infrared region to analyze samples.

Specification:

• Optical system with a Michelson type interferometer with an incidence angle of 30º, equipped with an ADA Advanced Dynamic Alignment system.
• Sealed and dissected compartment with electrolytic dehumidification system. A solid electrolyte membrane removes moisture from inside the interferometer and transfers this moisture to the outside environment in the form of water vapor allowing for stable analyses.
• Optical system consisting of a single beam.
• Germanium-coated KBr beam splitter.
• Ceramic infrared source stabilized by “Air Cooled” system.
• High sensitivity DLATGS (Deuterated Triglycine Sulfate Doped with L-Alanine) type detector equipped with temperature controller.
• Spectral range from 7800 cm-1 to 350 cm-1 (1280 - 28570 nm).
• Resolution of 0.25; 0.5; 1; two; 4; 8; 16 cm-1 for the mid- and far-infrared system and 2, 4, 8, 16 cm-1 for the near-infrared system.
• Signal-to-noise ratio greater than 60,000:1 for a 1-minute scan at 4 cm-1 resolution at 2200 cm-1 peak-to-peak.
• He-Ne laser.
• High speed scanning of 20 spectra/second is possible with OPTIONAL ITEMS.
• Moving Mirror Advanced Dynamic Alignment System (ADA) that monitors He-Ne laser conditions and compares to standard conditions and corrects automatically.
• Automatic accessory recognition.
• Allows conversion to near infrared measurements.
• Allows conversion to near infrared (FT-NIR) and far infrared (FAR) measurements by changing source, beam splitter and detector, easily performed by the user.
• The system can be made available on the network through the PC card and can be controlled from any point through the modem card and software.
• It has self-diagnostics at startup to check the optimal conditions of the electronic, optical and signal systems (IQ/OQ), laser verification.

Management and Sharing of Use of Multiuser Equipment Plan

The management of the EMU will be carried out by a Management Committee, which will be responsible for managing the use and operation of the equipment in the best possible way.

​

The responsibilities of the Steering Committee are:

  • Define procedures for guarding, operating and maintaining the EMU;

  • Manage the use and operation of the equipment;

  • Evaluate proposals for using the EMU by internal and external researchers at ITA

  • Guarantee the access of researchers from the Scientific Community to the EMU;

  • Establish strategies to guarantee resources for the maintenance of the EMU;

  • Gather the publications generated with the results obtained with the EMU.

 

The Users Committee, on the other hand, has the function of ensuring access and proper functioning of the equipment, and is composed of the researchers mentioned above.

 

The responsibilities of the Users Committee are:

  • Check records of equipment use and make suggestions to the Management Committee;

  • Continuously assess the condition of the equipment and identify the need for maintenance;

  • Discuss and present to the Management Committee the guidelines for schedules and use of equipment;

  • Submit an opinion with the documented statement of the intensity of use of the EMU, separating data from internal and external users;

  • Provide data related to publications generated with the results obtained by the EMU;

  • Hold half-yearly Committee meetings.

​

To use the EMU, interested parties must present proposals in one of the two calls that will take place during the year. Interested parties must submit a proposal according to the rules defined in the call.

 

Proposals will be judged by the Management Committee taking into account:

  1.  Scientific relevance of the study;

  2.  Priority for researchers and institutions in the state of São Paulo;

  3. Possibility of providing resources for the sustainability of the equipment (maintenance, insurance, etc.).

 

In addition, specific projects may be consulted/submitted at any time and their entry on the agenda will be the responsibility of the Coordinator and the Users Committee. Calls will be published on the IEFQ Chemistry Laboratory page.

Regulation on use and billing of services and use of EMU

The use of the EMU under the responsibility of the New Generation of Researchers Program (FAPESP nº 2022/03247-6) may occur by users internal or external to "BBLab". Internal users are characterized by individuals who develop research with the Project. These users have priority access to the EMU, under the scheduling and operation of the technical team. External users are individuals who do not have a research link with the laboratory, and in this case, the use of the equipment will be possible through the respective opening of calls for use, as well as availability of the equipment and technical team agenda.

Scheduling the Infrared Spectrometer (FTIR) in the LEAM

• The FTIR scheduling must be done prior to starting to use the equipment.
• In case of withdrawal, the agenda must be released immediately so that other users can use the schedule.
• If you need to use the equipment at times that have already been reserved, contact the user who made the reservation directly.
• The absence of an agenda for some equipment does not exempt the note in the respective blue observation notebooks.

​

New registrations on the agenda are authorized individually within a maximum period of 24 hours via the system. If you have difficulties scheduling, please contact us.
