| Abstract | In order to determine the ability of THz spectroscopy to analyse the composition of biological tissue, a phantom containing combinations of water and lipids was developed. Initially, the absorption coefficient and refractive index of five pure commercially available lipids was measured between 0 and 3 THz. A suitable lipid for phantom manufacture was then chosen and a series of oil-water emulsions were made using surfactants. The lipid content ranged from 0% to 100%. THz spectra of the absorption coefficient and refractive index of these emulsions were measured. Using spectral decomposition techniques based on the Beer Lambert law, the percentage of oil and water in the emulsion was determined. The results show good qualitative agreement with the known compositions. The absolute oil and water content showed a systematic error of 10%. These initial results demonstrate that THz spectroscopy has the potential to determine the composition of biological tissues |

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.
