| Abstract | In this paper we present the possibilities of cheap diagnostics based on optical fiber sensors and fluorescence lifetime measurements. Early diagnostics of pathological tissue changes, especially when it comes to lesions that are possibly cancerous is still undiscovered for commercial use. Methods used nowadays, which are focused on scanning large areas of the human body (MRI, CT) are sensitive, yet they cannot determine whether the tumor is benign or malignant. Optical methods based on fluorescence are seeing more and more use, and eventually they may become a standard when it comes to fast and non-invasive medical diagnostics. We present a fluorescence lifetime measurements of cancerous and healthy human tissue performed with the use of a very simple optical fiber sensor. Results obtained on a standard fluorescent dyes (fluorescein in NaOH solution) show, that this setup was capable of measuring decay times of the nanosecond region, which is enough for most of the endogenous fluorophores of human body. Results obtained for human tissue show a difference between fluorescence lifetimes of healthy and cancerous human tissue. This a preliminary experiment, just to determine both spatial and time resolution of our setup, our primary goal is to perform such an examination during standard surgical procedure. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
