This K99/R00 Mentored Research Career Development Award application is being submitted to the National Institute on Dental and Craniofacial Research (NIDCR). The candidate, Dr. Vuk Uskokovic, is a physical chemist and nanotechnologist who seeks to obtain additional training in the area of cell culture experimentation and other biological methods of analysis through this award. His aim is to develop research skills in the area of multifunctional and nanostructured biomaterials for reparation of hard tissues. The goals of this proposal would enhance Dr. Uskokovic's knowledge of fabrication of smart biomaterials for simultaneous time-controlled drug release and regeneration of diseased hard tissues. Proposed is the synthesis of calcium phosphate/polymer composite particles that encapsulate clinmadycin, a drug used in the treatment of osteomyelitis, as well as testing of the antimicrobial properties and osteinductive performance of the given material in vitro. The central hypothesis of the proposed study is that stoichiometry and the particle size of calcium phosphates can be used to tune the kinetics of the release of the encapsulated drug. Dr. Uskokovic will conduct his training and research activities under the guidance of an expert mentoring team that includes Drs. Tejal Desai, Grayson Marshall, Stefan Habelitz, Wu Li, and Peter Loomer. He will receive additional consulting from Drs. Mauro Ferrari, Antoni Tomsia, and Charles Hoover. Given that bioengineering and biomaterials research approaches to regeneration of oral and craniofacial tissues has been selected as one of the prioritized goals by the NIDCR (Objective I-5, Goal 1, NIDCR Strategic Plan 2009-2013), the goals of the current application will address highly actual oral, dental and craniofacial health problems. Training Dr. Uskokovic through this Pathway to Independence Award on top of his expertise in materials science and engineering and support by the UCSF Dental School, the most funded one by the NIH in the past 15 years, also complies with all three objectives of Goal 2 of the NIDCR Strategic Plan. Dr. Uskokovic will conduct a study which will involve: a) Synthesis of multifunctional therapeutic and osteoinductive calcium phosphate nanoparticles by means of co-precipitation from ultrasonically agitated emulsions; b) Drug release studies in bacterial and cell cultures. With respect to the proposed hypothesis, the central aim of this study is to derive fundamental correlations between the dissolution rate and drug delivery efficiency of calcium phosphate based carriers and their chemical composition and microstructure. This K99/R00 award is conceived to lead to an R01 grant, the writing of which will begin before the end of the award period.
