| Abstract | The transport and deformability of erythrocyte (RBC) and leukocyte (WBC) play great roles in both microcirculation in vivo and blood cell diagnosis. This paper used the microfabricated chips to study the transport and deformation of blood cells in typical sized rectangular microchannels. The test microchannel chips were fabricated by standard photolithography, ICP etching, and anode bonding with silicon wafers and glass covers. Flow field was magnified by an upright microscopy and images were captured by a high speed CCD camera. With a special designed image processing software, the images were filtered, enhanced, and edge detected for different purposes. The experiment results showed that the move and distribution of WBC in microchannel were significantly influenced by flow velocity, hematocrit, and other factors. The RBC occupy the center of channel and deform themselves to pass the narrow section of channel, in contrast to leukocyte, which deformed slightly and blocked the narrow section frequently. The measured results depicted that the deformability of blood cells subjected to many factors. This will be helpful in the design of blood cell separation devices and Keywords- |

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.
