| Abstract | For the purpose of bringing about the separation of bioparticles by means of dielectrophoresis, a field is considered which at any given point is constant in magnitude, and rotating at a fixed angular velocity. The field pattern causing this behaviour exhibits a two-dimensional variation in the xy plane, and moves in the x direction at a fixed velocity; at any instant, the field is invariant in the z direction. Because a rotating field is produced from linear motion of the field pattern, it is termed a 'rotlin field'. The way in which a rotlin field may be produced is explained. It is evident that spatial harmonics will be present, and that these might affect bioparticle behaviour. A bioparticle in such a field will experience both rotational and dielectrophoretic effects. A change in the angular velocity of the rotating field set up at each point by the rotlin field, and a change in the electrical conductivity of the immersion medium, can cause some particles to exhibit negative, while others exhibit positive, dielectrophoresis. The resulting difference in their movement can be used to bring about their separation. |

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.
