| Abstract | In this work, we create a gateless, depletion mode field effect transistor that operates as a molecular recognition based electronic sensor. The transistor consists of source and drain diffusions, a depletion-mode implant, and an insulating layer. The insulating layer is chemically modified by immobilized molecular receptors that enable miniaturized label-free molecular detection that is amenable to high-density array formats. Here, we describe the development of a microelectronic multi-sensor capable of reagent-free detection of a variety of biological macromolecules. Moreover, we study the effectiveness of the device for sensing macromolecules (such as proteins or DNA) quantitatively and in real time. Such capability can lead to the early detection of a variety of diseases and toxins including, but not limited to strains of cancer, influenza, and anthrax. The response of the sensor to buffer, proteins, and the antibody antigen-recognition event is also provided. |

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.
