| Abstract | Here we develop a novel immunosensor based on film bulk acoustic resonator (FBAR) to detect the biomarker of liver cancer. The alpha-fetoprotein (AFP), which is widely regarded as a serological marker for liver cancer in clinical diagnosis, is chosen as the target of the FBAR immunosensors. The surface of the FBAR was immobilized with monoclonal anti-AFP antibody as the specific bioprobe. The experimental results shows that the limit detectable AFP concentration of our proposed immunosensors is as low as 1 ng/ml, which is far less than that of quartz crystal microbalanc and comparable to that of enzyme-linked immunosorbent assay. Due to the compatibility of the fabrication of FBAR with CMOS process it can be mass produced, arrayed for analysis of multiple biochemical analyses simultaneously and integrated into a biochip, so that our proposed FBAR immunosensors can potentially be used for rapid multiple cancers diagnosis with low cost. |

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.
