| Abstract | The demand for more compact devices has led to the growing demand for system-on-chip (SoC) devices. In this reported work a system has been designed that would target a specific protein by using antibodies for the capture and binding. By using the TSMC 0.35 μm bio-microelectro-mechanical systems (BioMEMS) technology, a SoC device that incorporates the sensor and readout circuit into one chip is achieved. The sensor system will be able to detect the quantity of the magnetic beads on the sensor surface. The gold layer from the BioMEMS process has high sensitivity for capturing and fixing the target antibodies on top of the sensor. The system consists of a front-end sensing coil inductor and signal processor. The coil is used as the source of magnetic fields for magnetising the magnetic beads. Using a multiplexer to switch the sensor cells is a way to obtain the signal and infer the amount of the magnetic beads on a specific sensing region. Finally, UV epoxy was used to package the bonding wire of the sensor chip to make sure that biological fluids can directly drop onto the chip without short circuiting the system. |

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.
