| Abstract | Hydroxyapatite (HAP) is the constituent of calcium phosphate based bone cement and it is extensively used as a bone substitute and drug delivery vehicle in various biomedical applications. In the present study we investigated the release kinetics of ciprofloxacin loaded HAP and analyzed its ability to function as a targeted and sustained release drug carrier. Synthesis of HAP was carried out by combustion method using tartaric acid as a fuel and nitric acid as an oxidizer. Powder XRD and FTIR techniques were employed to characterize the phase purity of the drug carrier and to verify the chemical interaction between the drug and carrier. The synthesized powders were sieve separated to make two different drug carriers with different particle sizes and the surface topography of the pellets of the drug carrier was imaged by AFM. Surface area and porosity of the drug carrier was carried out using surface area analyzer. The in-vitro drug release kinetics was performed in simulated body fluid, at 37.3°C. The amount of ciprofloxacin released is measured using UV-visible spectroscopy following the characteristic λ $_{max}$ of 278 nm. The release saturates around 450 h which indicates that it can be used as a targeted and sustained release carrier for bone infections. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
