| Abstract | Magnetic particle imaging (MPI), as introduced by Gleich and Weizenecker, is based on utilizing the nonlinear magnetization response M for detection of superparamagnetic iron oxide nanoparticles (MNP). The excited M contains not only the fundamental excitation frequency ω0 but also its harmonics when applying an ac excitation magnetic field. To improve the detection sensitivity for the magnetization M of MNP and the imaging technique based on the detection of a second harmonic response, a 2D imaging system consisting of four magnetic fields, dc bias field Hdc, ac modulation field Hac, gradient field of Z-axis and gradient field of X-axis have been constructed. The advantage of the detection of a second harmonic response is that no large ac modulation field Hac is required. This study demonstrated a MNP detection method using a second harmonic of magnetic response. The position of the 10-microlitre MNP sample was clearly indicated in 2D imaging. |

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.
