The National Institute of Biomedical Imaging and Bioengineering (NIBIB) is authorized by the National Institute of Biomedical Imaging and Bioengineering Establishment Act H.R. 1795, which was signed into law by President William Clinton on December 29, 2000, as Public Law 106-580. It is one of 27 institutes and centers of the National Institutes of Health (NIH).
The NIBIB Off-Campus Research Program brings together the research communities of biomedical imaging, bioengineering, physical sciences, and life sciences to promote human health. The off-campus research program is divided into four parts:
Department of Applied Science and Technology (DAST): This department supports the development of innovative biomedical imaging technologies to transform NIBIB's understanding of biological and disease processes to improve diagnosis, image-guided therapies and human health;
Department of Discovery Science and Technology (DDST): This department supports the development of biomedical technologies (without preference for any disease or application) that are directly linked to human physiology and control biological functions to establish the next generation of human health interventions. The department also supports research to advance the design and deployment of future technology-driven interventions;
Department of Health Informatics Technology (DHIT): The focus of this department is to support the development of science and technology to process and evaluate complex biomedical information in order to develop solutions to real-world healthcare problems. This research builds on practical, patient-centered applications;
Department of Interdisciplinary Training (DIDT): Funding research training at all vocational levels.
The NIBIB Intramural Research Program plays a key role in fulfilling the Institute's mission by combining basic, translational, and clinical sciences. The program includes laboratories, departments, and core facilities, all located at the NIH main campus in Bethesda, Maryland. They are:
Laboratory of Cell Imaging and Macromolecular Biophysics (LCIMB): Specialized in the development and application of cutting-edge technologies based on engineering, mathematics and physical sciences to solve problems in biology and medicine. It collaborates with scientists on campus and proposes and develops theoretical and experimental methods that are important for the long-term needs of the NIH. Its unique expertise covers technologies of all sizes, from near-atomic resolution to complete organisms;
Laboratory of Polymer Assembly Kinetics (DMA): The Laboratory of Macromolecular Assembly Kinetics has developed biophysical methods to study protein interactions and the assembly of multi-protein complexes. The hallmark of multiprotein complexes is polyvalent interaction and cooperation. In the molecular mechanisms of cellular processes, these constitute ubiquitous mechanisms for information integration and transmission. Therefore, NIBIB focuses on developing methods for multi-component systems in which several different macromolecular components interact to allow for the binding and dissociation of different coexisting complexes in different states. NIBIB is interested in characterizing the number of assembly states, as well as their size, shape, and interaction energy. As a complement to crystallographic techniques, this solution interaction study can provide information on the assembly principles of structural polycrystalline multiprotein complexes;
Molecular Tracer and Imaging Core Facility: The PET Radiochemistry and Imaging Core Facility has developed new methods for combining radionuclides and fluorophores into molecules to study biologically important processes. All NIBIB projects support research initiated by the lead researcher. NIBIB seeks to collaborate with clinical and biological researchers who share the same goal with NIBIB to provide new imaging tools for clinical research and biological process research. NIBIB's research work is motivated by the desire to improve understanding of human biology and disease and to generate tools with clinical applications. Probes produced by NIBIB are suitable for many important biological processes, including inflammation, metabolism, proliferation, angiogenesis, metastasis, lymphogenesis, and apoptosis;
The NIBIB Biophotonics section develops probes and techniques for diffraction-limited and subdiffraction-limited fluorescence imaging of cells and tissues. The main focus is on the development of new and improved existing genetically encoded fluorescent proteins for use as markers and sensors. Methods and techniques include confocal , TIRF and wide field of view microscopy, single-molecule imaging, fluorescence spectroscopy, and protein engineering;
Immunoengineering Section: The Department of Immunoengineering uses a mechanism-based immunological approach to develop immunoactive biomaterials for regenerative medicine through a bottom-up approach. The immune system is a key mediator of tissue homeostasis and disease. After implantation of a biomaterial scaffold, the immune system response is activated and may have pathological side effects, including fibrosis or destructive inflammation. In addition, tissue growth and wound healing are regulated by the immune response. By understanding how people's immune systems interact with materials in the context of traumatic injury, combined with advances in biopolymers and cellular engineering, NIBIB will attempt to program immune responses to facilitate scaffold integration and tissue growth. This information is essential for the advancement of next-generation materials for non-integrated devices (i.e. pacemakers, drug delivery devices, cosmetic implants) as well as integrated medical devices (stents for tissue repair);
Mechanical Biology Section: The Mechanical Biology segment focuses on the development and use of advanced atomic force microscopy (AFM) techniques for cellular and tissue mechanics research. NIBIB combines and applies a variety of multidisciplinary knowledge to study the most pressing mechalogically biological problems, including high-spatiotemporal resolution AFM and confocal fluorescence microscopy, image analysis, and mathematical modeling.
The mechanobiology section attempts to understand several important biological processes by applying principles of physics and engineering, in particular: the molecular mechanical regulation of the actin cortex of melanoma cells; For deciphering the self-organizing solid tumor microenvironment in cancer biology; and the development and maturation of the anisotropic mechanical properties of the inner ear sensory and non-sensory epithelial tissue using novel non-contact AFM methods.
In addition, the lab has developed new AFM methods to study rapid multiparametric and multidimensional cellular and tissue processes and advanced state-of-the-art AFM imaging methods for high spatiotemporal and quantitative nanomechanical mapping;
Quantitative Medical Imaging Laboratory: Methods developed by quantitative medical imaging laboratories to obtain biomarkers from data obtained by non-invasive imaging techniques such as magnetic resonance imaging, MRI, which provide information about anatomy and physiology and provide new, accurate and reliable tools for evaluating various medical conditions;
Biomedical Engineering and Physical Sciences Commons (BEPS) across NIH: Biomedical Engineering and Physical Sciences (BEPS) shared resources support NIH's on-campus foundational and clinical scientists' applications in engineering, physics, imaging, measurement, and analysis. Located in the heart of the NIH's main campus, BEPS offers expertise in a wide range of technologies, from near-atomic resolution to intact organisms;
Advanced Imaging and Microscopy Commons (AIM) across NIH: Advanced Imaging and Microscopy Resources are shared resources across NIH for accommodating, operating, propagating, and improving non-commercial prototype optical imaging systems developed by NIH. AIM's facilities are available to the entire NIH on-campus research community.
